    <summary>Provides information about a specific culture (called a *locale* for unmanaged code development). The information includes the names for the culture, the writing system, the calendar used, the sort order of strings, and formatting for dates and numbers.</summary>

      ## Remarks

The <xref:System.Globalization.CultureInfo> class provides information associated with a specific culture, such as language, sublanguage, country/region, calendar, and conventions. This class also provides access to culture-specific instances of the <xref:System.Globalization.DateTimeFormatInfo>, <xref:System.Globalization.NumberFormatInfo>, <xref:System.Globalization.CompareInfo>, and <xref:System.Globalization.TextInfo> objects. These objects contain the information required for culture-specific operations, such as casing, formatting dates and numbers, and comparing strings. The <xref:System.Globalization.CultureInfo> class is used either directly or indirectly by classes that format, parse, or manipulate culture-specific data, such as <xref:System.String>, <xref:System.DateTime>, <xref:System.DateTimeOffset>, and the numeric types.

## Culture names and identifiers

The <xref:System.Globalization.CultureInfo> class specifies a unique name for each culture, based on RFC 4646. The name is a combination of an ISO 639 two-letter or three-letter lowercase culture code associated with a language and an ISO 3166 two-letter uppercase subculture code associated with a country or region. In addition, for apps that are running under Windows 10 or later, culture names that correspond to valid BCP-47 language tags are supported.

> [!NOTE]
> When a culture name is passed to a class constructor or a method such as <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> or <xref:System.Globalization.CultureInfo>, its case is not significant.

The format for the culture name based on RFC 4646 is *`languagecode2`*-*`country/regioncode2`*, where *`languagecode2`* is the two-letter language code and *`country/regioncode2`* is the two-letter subculture code. Examples include `ja-JP` for Japanese (Japan) and `en-US` for English (United States). In cases where a two-letter language code is not available, a three-letter code as defined in ISO 639-3 is used.

Some culture names also specify an ISO 15924 script. For example, Cyrl specifies the Cyrillic script and Latn specifies the Latin script. A culture name that includes a script uses the pattern *`languagecode2`*-*`scripttag`*-*`country/regioncode2`*. An example of this type of culture name is `uz-Cyrl-UZ` for Uzbek (Cyrillic, Uzbekistan). On Windows operating systems before Windows Vista, a culture name that includes a script uses the pattern *`languagecode2`*-*`country/regioncode2`*-*`scripttag`*, for example, `uz-UZ-Cyrl` for Uzbek (Cyrillic, Uzbekistan).

A neutral culture is specified by only the two-letter, lowercase language code. For example, `fr` specifies the neutral culture for French, and `de` specifies the neutral culture for German.

> [!NOTE]
> There are two culture names that contradict this rule. The cultures Chinese (Simplified), named `zh-Hans`, and Chinese (Traditional), named `zh-Hant`, are neutral cultures. The culture names represent the current standard and should be used unless you have a reason for using the older names `zh-CHS` and `zh-CHT`.

A culture identifier is a standard international numeric abbreviation and has the components necessary to uniquely identify one of the installed cultures. Your application can use predefined culture identifiers or define custom identifiers.

Certain predefined culture names and identifiers are used by this and other classes in the <xref:System.Globalization?displayProperty=fullName> namespace. For detailed culture information for Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47).

The culture names and identifiers represent only a subset of cultures that can be found on a particular computer. Windows versions or service packs can change the available cultures. Applications can add custom cultures using the <xref:System.Globalization.CultureAndRegionInfoBuilder> class. Users can add their own custom cultures using the [Microsoft Locale Builder](https://www.microsoft.com/download/details.aspx?id=41158) tool. Microsoft Locale Builder is written in managed code using the `CultureAndRegionInfoBuilder` class.

Several distinct names are closely associated with a culture, notably the names associated with the following class members:

- <xref:System.Globalization.CultureInfo.ToString*?displayProperty=nameWithType>
- <xref:System.Globalization.CultureInfo.Name?displayProperty=nameWithType>
- <xref:System.Globalization.CompareInfo.Name?displayProperty=nameWithType>

## Invariant, neutral, and specific cultures

The cultures are generally grouped into three sets: invariant cultures, neutral cultures, and specific cultures.

An invariant culture is culture-insensitive. Your application specifies the invariant culture by name using an empty string ("") or by its identifier. <xref:System.Globalization.CultureInfo.InvariantCulture> defines an instance of the invariant culture. It is associated with the English language but not with any country/region. It is used in almost any method in the `Globalization` namespace that requires a culture.

A neutral culture is a culture that is associated with a language but not with a country/region. A specific culture is a culture that is associated with a language and a country/region. For example, `fr` is the neutral name for the French culture, and `fr-FR` is the name of the specific French (France) culture. Note that Chinese (Simplified) and Chinese (Traditional) are also considered neutral cultures.

Creating an instance of a <xref:System.Globalization.CompareInfo> class for a neutral culture is not recommended because the data it contains is arbitrary. To display and sort data, specify both the language and region. Additionally, the <xref:System.Globalization.CompareInfo.Name> property of a <xref:System.Globalization.CompareInfo> object created for a neutral culture returns only the country and does not include the region.

The defined cultures have a hierarchy in which the parent of a specific culture is a neutral culture and the parent of a neutral culture is the invariant culture. The <xref:System.Globalization.CultureInfo.Parent> property contains the neutral culture associated with a specific culture. Custom cultures should define the <xref:System.Globalization.CultureInfo.Parent> property in conformance with this pattern.

If the resources for a specific culture are not available in the operating system, the resources for the associated neutral culture are used. If the resources for the neutral culture are not available, the resources embedded in the main assembly are used. For more information on the resource fallback process, see [Packaging and Deploying Resources](/dotnet/framework/resources/packaging-and-deploying-resources-in-desktop-apps).

The list of locales in the Windows API is slightly different from the list of cultures supported by .NET. If interoperability with Windows is required, for example, through the p/invoke mechanism, the application should use a specific culture that's defined for the operating system. Use of the specific culture ensures consistency with the equivalent Windows locale, which is identified with a locale identifier that is the same as <xref:System.Globalization.CultureInfo.LCID>.

A <xref:System.Globalization.DateTimeFormatInfo> or a <xref:System.Globalization.NumberFormatInfo> can be created only for the invariant culture or for specific cultures, not for neutral cultures.

If <xref:System.Globalization.DateTimeFormatInfo.Calendar?displayProperty=nameWithType> is the <xref:System.Globalization.TaiwanCalendar> but the <xref:System.Threading.Thread.CurrentCulture?displayProperty=nameWithType> is not set to `zh-TW`, then <xref:System.Globalization.DateTimeFormatInfo.NativeCalendarName?displayProperty=nameWithType>, <xref:System.Globalization.DateTimeFormatInfo.GetEraName*?displayProperty=nameWithType>, and <xref:System.Globalization.DateTimeFormatInfo.GetAbbreviatedEraName*?displayProperty=nameWithType> return an empty string ("").

## Custom cultures

On Windows, you can create custom locales. For more information, see [Custom locales](/windows/win32/intl/custom-locales).

## CultureInfo and cultural data

.NET derives its cultural data from two different sources, depending on the OS:

- On Unix platforms or Windows 10 and later versions, cultural data is provided by the [International Components for Unicode (ICU) Library](https://icu.unicode.org/). The specific version of the ICU Library depends on the individual operating system.
- On Windows 8.1 and earlier versions, cultural data is provided by the Windows operating system.

Because of this, a culture available on a particular .NET implementation, platform, or version may not be available on a different .NET implementation, platform, or version.

Some `CultureInfo` objects differ depending on the underlying platform. In particular, `zh-CN`, or Chinese (Simplified, China) and `zh-TW`, or Chinese (Traditional, Taiwan), are available cultures on Windows systems, but they are aliased cultures on Unix systems. "zh-CN" is an alias for the "zh-Hans-CN" culture, and "zh-TW" is an alias for the "zh-Hant-TW" culture. Aliased cultures are not returned by calls to the <xref:System.Globalization.CultureInfo.GetCultures*> method and may have different property values, including different <xref:System.Globalization.CultureInfo.Parent> cultures, than their Windows counterparts. For the `zh-CN` and `zh-TW` cultures, these differences include the following:

- On Windows systems, the parent culture of the "zh-CN" culture is "zh-Hans", and the parent culture of the "zh-TW" culture is "zh-Hant". The parent culture of both these cultures is "zh". On Unix systems, the parents of both cultures are "zh". This means that, if you don't provide culture-specific resources for the "zh-CN" or "zh-TW" cultures but do provide a resources for the neutral "zh-Hans" or "zh-Hant" culture, your application will load the resources for the neutral culture on Windows but not on Unix. On Unix systems, you must explicitly set the thread's <xref:System.Globalization.CultureInfo.CurrentUICulture> to either "zh-Hans" or "zh-Hant".

- On Windows systems, calling <xref:System.Globalization.CultureInfo.Equals*?displayProperty=nameWithType> on an instance that represents the "zh-CN" culture and passing it a "zh-Hans-CN" instance returns `true`. On Unix systems, the method call returns `false`. This behavior also applies to calling <xref:System.Globalization.CultureInfo.Equals*> on a "zh-TW" <xref:System.Globalization.CultureInfo> instance and passing it a "zh-Hant-Tw" instance.

## Dynamic culture data

Except for the invariant culture, culture data is dynamic. This is true even for the predefined cultures. For example, countries or regions adopt new currencies, change their spellings of words, or change their preferred calendar, and culture definitions change to track this. Custom cultures are subject to change without notice, and any specific culture might be overridden by a custom replacement culture. Also, as discussed below, an individual user can override cultural preferences. Applications should always obtain culture data at runtime.

> [!CAUTION]
> When saving data, your application should use the invariant culture, a binary format, or a specific culture-independent format. Data saved according to the current values associated with a particular culture, other than the invariant culture, might become unreadable or might change in meaning if that culture changes.

## The current culture and current UI culture

Every thread in a .NET application has a current culture and a current UI culture. The current culture determines the formatting conventions for dates, times, numbers, and currency values, the sort order of text, casing conventions, and the ways in which strings are compared. The current UI culture is used to retrieve culture-specific resources at runtime.

> [!NOTE]
> For information on how the current and current UI culture is determined on a per-thread basis, see the [Culture and threads](#culture-and-threads) section. For information on how the current and current UI culture is determined on threads performing task-based asynchronous operations, see the [Culture and task-based asynchronous operations](#culture-and-task-based-asynchronous-operations) section.

For more detailed information on the current culture, see the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property. For more detailed information on the current UI culture, see the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property topic.

### Retrieve the current and current UI cultures

You can get a <xref:System.Globalization.CultureInfo> object that represents the current culture in either of two ways:

- By retrieving the value of the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property.
- By retrieving the value of the [Thread.CurrentThread.CurrentCulture](xref:System.Threading.Thread.CurrentCulture) property.

The following example retrieves both property values, compares them to show that they are equal, and displays the name of the current culture.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/Current1.cs" id="Snippet1":::

You can get a <xref:System.Globalization.CultureInfo> object that represents the current UI culture in either of two ways:

- By retrieving the value of the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property.

- By retrieving the value of the [Thread.CurrentThread.CurrentUICulture](xref:System.Threading.Thread.CurrentUICulture) property.

The following example retrieves both property values, compares them to show that they are equal, and displays the name of the current UI culture.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/CurrentUI1.cs" id="Snippet2":::

### Set the current and current UI cultures

To change the culture and UI culture of a thread, do the following:

1. Instantiate a <xref:System.Globalization.CultureInfo> object that represents that culture by calling a <xref:System.Globalization.CultureInfo> class constructor and passing it the name of the culture. The <xref:System.Globalization.CultureInfo.%23ctor(System.String)> constructor instantiates a <xref:System.Globalization.CultureInfo> object that reflects user overrides if the new culture is the same as the current Windows culture. The <xref:System.Globalization.CultureInfo.%23ctor(System.String,System.Boolean)> constructor allows you to specify whether the newly instantiated <xref:System.Globalization.CultureInfo> object reflects user overrides if the new culture is the same as the current Windows culture.

2. Assign the <xref:System.Globalization.CultureInfo> object to the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> or <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property.

The following example retrieves the current culture. If it is anything other than the French (France) culture, it changes the current culture to French (France). Otherwise, it changes the current culture to French (Luxembourg).

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/Change1.cs" id="Snippet3":::

The following example retrieves the current culture. If it is anything other the Slovenian (Slovenia) culture, it changes the current culture to Slovenian (Slovenia). Otherwise, it changes the current culture to Croatian (Croatia).

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/ChangeUI1.cs" id="Snippet4":::

## Get all cultures

You can retrieve an array of specific categories of cultures or of all the cultures available on the local computer by calling the <xref:System.Globalization.CultureInfo.GetCultures*> method. For example, you can retrieve custom cultures, specific cultures, or neutral cultures either alone or in combination.

The following example calls the <xref:System.Globalization.CultureInfo.GetCultures*> method twice, first with the <xref:System.Globalization.CultureTypes?displayProperty=nameWithType> enumeration member to retrieve all custom cultures, and then with the <xref:System.Globalization.CultureTypes?displayProperty=nameWithType> enumeration member to retrieve all replacement cultures.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/GetCultures1.cs" id="Snippet5":::

## Culture and threads

When a new application thread is started, its current culture and current UI culture are defined by the current system culture, and not by the current thread culture. The following example illustrates the difference. It sets the current culture and current UI culture of an application thread to the French (France) culture (fr-FR). If the current culture is already fr-FR, the example sets it to the English (United States) culture (en-US). It displays three random numbers as currency values and then creates a new thread, which, in turn, displays three more random numbers as currency values. But as the output from the example shows, the currency values displayed by the new thread do not reflect the formatting conventions of the French (France) culture, unlike the output from the main application thread.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/defaultthread1.cs" id="Snippet1":::

You can set the culture and UI culture of all threads in an application domain by assigning a <xref:System.Globalization.CultureInfo> object that represents that culture to the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> and <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> properties. The following example uses these properties to ensure that all threads in the default application domain share the same culture.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/setthreads1.cs" id="Snippet3":::

When you assign values to the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> and <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> properties, the culture and UI culture of the threads in the application domain also change if they have not explicitly been assigned a culture. However, these threads reflect the new culture settings only while they execute in the current application domain. If these threads execute in another application domain, their culture becomes the default culture defined for that application domain. As a result, we recommend that you always set the culture of the main application thread, and not rely on the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> and <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> properties to change it.

## Culture and task-based asynchronous operations

The [task-based asynchronous programming pattern](/dotnet/standard/parallel-programming/task-based-asynchronous-programming) uses <xref:System.Threading.Tasks.Task> and <xref:System.Threading.Tasks.Task`1> objects to asynchronously execute delegates on thread pool threads. The specific thread on which a particular task runs is not known in advance, but is determined only at runtime.

Culture is part of an asynchronous operation's context. In other words, asynchronous operations by default inherit the values of the <xref:System.Globalization.CultureInfo.CurrentCulture> and <xref:System.Globalization.CultureInfo.CurrentUICulture> properties of the thread from which they are launched. If the current culture or current UI culture differs from the system culture, the current culture crosses thread boundaries and becomes the current culture of the thread pool thread that is executing an asynchronous operation.

The following example provides a simple illustration. The example defines a <xref:System.Func`1> delegate, `formatDelegate`, that returns some numbers formatted as currency values. The example changes the current system culture to either French (France) or, if French (France) is already the current culture, English (United States). It then:

- Invokes the delegate directly so that it runs synchronously on the main app thread.
- Creates a task that executes the delegate asynchronously on a thread pool thread.
- Creates a task that executes the delegate synchronously on the main app thread by calling the <xref:System.Threading.Tasks.Task.RunSynchronously*?displayProperty=nameWithType> method.

As the output from the example shows, when the current culture is changed to French (France), the current culture of the thread from which tasks are invoked asynchronously becomes the current culture for that asynchronous operation.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/Overview/asyncculture1.cs" id="Snippet1":::

## CultureInfo object serialization

When a <xref:System.Globalization.CultureInfo> object is serialized, all that is actually stored is <xref:System.Globalization.CultureInfo.Name> and <xref:System.Globalization.CultureInfo.UseUserOverride*>. It is successfully deserialized only in an environment where that <xref:System.Globalization.CultureInfo.Name> has the same meaning. The following three examples show why this is not always the case:

- If the <xref:System.Globalization.CultureInfo.CultureTypes> property value is <xref:System.Globalization.CultureTypes.InstalledWin32Cultures?displayProperty=nameWithType>, and if that culture was first introduced in a particular version of the Windows operating system, it is not possible to deserialize it on an earlier version of Windows. For example, if a culture was introduced in Windows 10, it cannot be deserialized on Windows 8.

- If the <xref:System.Globalization.CultureInfo.CultureTypes> value is <xref:System.Globalization.CultureTypes.UserCustomCulture?displayProperty=nameWithType>, and the computer on which it is deserialized does not have this user custom culture installed, it is not possible to deserialize it.

- If the <xref:System.Globalization.CultureInfo.CultureTypes> value is <xref:System.Globalization.CultureTypes.ReplacementCultures?displayProperty=nameWithType>, and the computer on which it is deserialized does not have this replacement culture, it deserializes to the same name, but not all of the same characteristics. For example, if `en-US` is a replacement culture on computer A, but not on computer B, and if a <xref:System.Globalization.CultureInfo> object referring to this culture is serialized on computer A and deserialized on computer B, then none of the custom characteristics of the culture are transmitted. The culture deserializes successfully, but with a different meaning.

## Control Panel overrides

The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. In general, your applications should honor these user overrides.

If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars>, the results of the methods and the values of the properties are undefined.

## Alternate sort orders

Some cultures support more than one sort order. For example:

- The Spanish (Spain) culture has two sort orders: the default international sort order, and the traditional sort order. When you instantiate a <xref:System.Globalization.CultureInfo> object with the `es-ES` culture name, the international sort order is used. When you instantiate a <xref:System.Globalization.CultureInfo> object with the `es-ES-tradnl` culture name, the traditional sort order is used.
- The `zh-CN` (Chinese (Simplified, PRC)) culture supports two sort orders:  by pronunciation (the default) and by stroke count. When you instantiate a <xref:System.Globalization.CultureInfo> object with the `zh-CN` culture name, the default sort order is used. When you instantiate a <xref:System.Globalization.CultureInfo> object with a local identifier of 0x00020804, strings are sorted by stroke count.

The following table lists the cultures that support alternate sort orders and the identifiers for the default and alternate sort orders.

| Culture name | Culture                 | Default sort name and identifier | Alternate sort name and identifier    |
|--------------|-------------------------|----------------------------------|---------------------------------------|

| zh-SG        | Chinese (Singapore)     | Pronunciation: 0x00001004        | Stroke Count: 0x00021004              |
| zh-MO        | Chinese (Macao SAR)     | Pronunciation: 0x00001404        | Stroke Count: 0x00021404              |
| ja-JP        | Japanese (Japan)        | Default: 0x00000411              | Unicode: 0x00010411                   |
| ko-KR        | Korean (Korea)          | Default: 0x00000412              | Korean Xwansung - Unicode: 0x00010412 |
| de-DE        | German (Germany)        | Dictionary: 0x00000407           | Phone Book Sort DIN: 0x00010407       |
| hu-HU        | Hungarian (Hungary)     | Default: 0x0000040e              | Technical Sort: 0x0001040e            |
| ka-GE        | Georgian (Georgia)      | Traditional: 0x00000437          | Modern Sort: 0x00010437               |

## Example

The following example shows how to create a <xref:System.Globalization.CultureInfo> object for Spanish (Spain) with the international sort and another <xref:System.Globalization.CultureInfo> object with the traditional sort.

## Remarks

Predefined culture identifiers for cultures available on Windows system are listed in the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47).

 In most cases, the `culture` parameter is mapped to the corresponding National Language Support (NLS) locale identifier. The value of the `culture` parameter becomes the value of the <xref:System.Globalization.CultureInfo.LCID> property of the new <xref:System.Globalization.CultureInfo>.

 We recommend that you call the locale name constructor <xref:System.Globalization.CultureInfo.%23ctor*?displayProperty=nameWithType>, because locale names are preferable to LCIDs. For custom locales, a locale name is required.

 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. If the specified culture identifier matches the culture identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> that uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo> (for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>) the results of the methods and the values of the properties are undefined.

 If the specified culture identifier does not match the identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> that uses the default values for the specified culture.

 The <xref:System.Globalization.CultureInfo.UseUserOverride> property is always set to `true`.

 For example, suppose that Arabic (Saudi Arabia) is the current Windows culture and the user has changed the calendar from Hijri to Gregorian.

- With `CultureInfo("0x0401")` (culture name ar-SA), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.GregorianCalendar> (which is the user setting) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.
- With `CultureInfo("0x041E")` (culture name th-TH), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.

> [!NOTE]
> For backwards compatibility, a culture constructed using a `culture` parameter of 0x0004 or 0x7c04 has a <xref:System.Globalization.CultureInfo.Name> property of `zh-CHS` or `zh-CHT`, respectively. You should instead prefer to construct the culture using the current standard culture names of `zh-Hans` or `zh-Hant`, unless you have a reason for using the older names.

> [!NOTE]
> LCIDs are being deprecated, and implementers are strongly encouraged to use newer versions of APIs that support BCP 47 locale names instead. Each LCID can be represented by a BCP 47 locale name, but the reverse is not true. The LCID range is restricted and unable to uniquely identify all the possible combinations of language and region.

## Remarks

For a list of predefined culture names on Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag.

 If `name` is <xref:System.String.Empty?displayProperty=nameWithType>, the constructor creates an instance of the invariant culture; this is equivalent to retrieving the value of the <xref:System.Globalization.CultureInfo.InvariantCulture> property.

 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. If the culture identifier associated with `name` matches the culture identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> object that uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 If the culture identifier associated with `name` does not match the culture identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> object that uses the default values for the specified culture.

 The <xref:System.Globalization.CultureInfo.UseUserOverride> property is always set to `true`.

 For example, suppose that Arabic (Saudi Arabia) is the current culture of Windows and the user changed the calendar from Hijri to Gregorian:

- With `CultureInfo("ar-SA")`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.GregorianCalendar> (which is the user setting) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.
- With `CultureInfo("th-TH")`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.

The <xref:System.Globalization.CultureInfo.LCID> property of the new <xref:System.Globalization.CultureInfo> is set to the culture identifier associated with the specified name.

## Examples
 The following example retrieves the current culture. If it is anything other than the French (France) culture, it calls the <xref:System.Globalization.CultureInfo.%23ctor(System.String)> constructor to instantiate a <xref:System.Globalization.CultureInfo> object that represents the French (France) culture and makes it the current culture. Otherwise, it instantiates a <xref:System.Globalization.CultureInfo> object that represents the French (Luxembourg) culture and makes it the current culture.

## Remarks

Predefined culture identifiers available on Windows systems are listed in the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47).

 In most cases, the `culture` parameter is mapped to the corresponding National Language Support (NLS) locale identifier. The value of the `culture` parameter becomes the value of the <xref:System.Globalization.CultureInfo.LCID> property of the new <xref:System.Globalization.CultureInfo>.

 We recommend that you call the locale name constructor <xref:System.Globalization.CultureInfo.%23ctor*?displayProperty=nameWithType>, because locale names are preferable to LCIDs. For custom locales, a locale name is required.

 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 Applications should typically not disallow user overrides. Disallowing overrides does not itself guarantee data stability. For more information, see the blog entry [Culture data shouldn't be considered stable (except for Invariant)](/archive/blogs/shawnste/culture-data-shouldnt-be-considered-stable-except-for-invariant).

 If the <xref:System.Globalization.CultureInfo.UseUserOverride> property is set to `true` and the specified culture identifier matches the identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> that uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 Otherwise, this constructor creates a <xref:System.Globalization.CultureInfo> that uses the default values for the specified culture.

 The value of the `useUserOverride` parameter becomes the value of the <xref:System.Globalization.CultureInfo.UseUserOverride> property.

For example, suppose that Arabic (Saudi Arabia) is the current culture of Windows and the user has changed the calendar from Hijri to Gregorian.

- With `CultureInfo("0x0401", true)` (culture name ar-SA), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.GregorianCalendar> (which is the user setting) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.
- With `CultureInfo("0x0401", false)` (culture name ar-SA), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.HijriCalendar> (which is the default calendar for ar-SA) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `false`.
- With `CultureInfo("0x041E", true)` (culture name th-TH), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.
- With `CultureInfo("0x041E", false)` (culture name th-TH), <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `false`.

> [!NOTE]
> For backwards compatibility, a culture constructed using a `culture` parameter of 0x0004 or 0x7c04 will have a <xref:System.Globalization.CultureInfo.Name> property of zh-CHS or zh-CHT, respectively. You should instead prefer to construct the culture using the current standard culture names of `zh-Hans` or zh-Hant, unless you have a reason for using the older names.

> [!NOTE]
> LCIDs are being deprecated, and implementers are strongly encouraged to use newer versions of APIs that support BCP 47 locale names instead. Each LCID can be represented by a BCP 47 locale name, but the reverse is not true. The LCID range is restricted and unable to uniquely identify all the possible combinations of language and region.

## Remarks

For a list of predefined culture names, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag.

If `name` is <xref:System.String.Empty?displayProperty=nameWithType>, the constructor creates an instance of the invariant culture; this is equivalent to retrieving the value of the <xref:System.Globalization.CultureInfo.InvariantCulture> property.

 The user might choose to override some of the values associated with the current Windows culture through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 Applications should typically not disallow user overrides. Disallowing overrides does not itself guarantee data stability. For more information, see the blog entry [Culture data shouldn't be considered stable (except for Invariant)](/archive/blogs/shawnste/culture-data-shouldnt-be-considered-stable-except-for-invariant).

 If the <xref:System.Globalization.CultureInfo.UseUserOverride> property is set to `true` and the culture identifier associated with the specified culture name matches the culture identifier of the current Windows culture, this constructor creates a <xref:System.Globalization.CultureInfo> that uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 Otherwise, this constructor creates a <xref:System.Globalization.CultureInfo> that uses the default values for the specified culture.

 The value of the `useUserOverride` parameter becomes the value of the <xref:System.Globalization.CultureInfo.UseUserOverride> property.

 For example, suppose that Arabic (Saudi Arabia) is the current culture of Windows and the user changed the calendar from Hijri to Gregorian.

- With `CultureInfo("ar-SA", true)`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.GregorianCalendar> (which is the user setting) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.

- With `CultureInfo("ar-SA", false)`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.HijriCalendar> (which is the default calendar for ar-SA) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `false`.

- With `CultureInfo("th-TH", true)`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `true`.

- With `CultureInfo("th-TH", false)`, <xref:System.Globalization.CultureInfo.Calendar*> is set to <xref:System.Globalization.ThaiBuddhistCalendar> (which is the default calendar for th-TH) and <xref:System.Globalization.CultureInfo.UseUserOverride*> is set to `false`.

 The <xref:System.Globalization.CultureInfo.LCID> property of the new <xref:System.Globalization.CultureInfo> is set to the culture identifier associated with the specified name.

## Remarks
 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 Therefore, if <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true`, the value of this property might be different from the default calendar used by the culture.

 Your application changes the calendar used by the current <xref:System.Globalization.CultureInfo> by setting the <xref:System.Globalization.DateTimeFormatInfo.Calendar> property of <xref:System.Globalization.CultureInfo.DateTimeFormat*>, which is an instance of the <xref:System.Globalization.DateTimeFormatInfo> class. The new calendar must be one of the calendars listed in <xref:System.Globalization.CultureInfo.OptionalCalendars*>. <xref:System.Globalization.CultureInfo.DateTimeFormat*> also includes other properties that customize the date and time formatting associated with that <xref:System.Globalization.DateTimeFormatInfo.Calendar*>.

## Remarks

Information, such as the default culture and format patterns, is cached the first time it's requested. That information can change, for example, when the user modifies the regional and language options portion of Control Panel. However, the <xref:System.Globalization.CultureInfo> class does not automatically detect changes in the system settings.

 The <xref:System.Globalization.CultureInfo.ClearCachedData*> method clears the cache of <xref:System.Globalization.CultureInfo> objects created by <xref:System.Globalization.CultureInfo.GetCultureInfo*> and refreshes the information in the <xref:System.Globalization.CultureInfo.CurrentCulture*>, <xref:System.Globalization.CultureInfo.CurrentUICulture*>, and <xref:System.Globalization.RegionInfo.CurrentRegion*> properties, based on the current system settings.

 The <xref:System.Globalization.CultureInfo.ClearCachedData*> method does not refresh the information in the <xref:System.Threading.Thread.CurrentCulture?displayProperty=nameWithType> property for existing threads. However, future threads will have any new <xref:System.Globalization.CultureInfo> property values.

## Remarks
 The clone is writable even if the original <xref:System.Globalization.CultureInfo> is read-only. Therefore, the properties of the clone can be modified.

 A shallow copy of an object is a copy of the object only. If the object contains references to other objects, the shallow copy does not create copies of the referred objects. It refers to the original objects instead. In contrast, a deep copy of an object creates a copy of the object and a copy of everything directly or indirectly referenced by that object.

 The <xref:System.Globalization.CultureInfo.Clone*> method creates an enhanced shallow copy. The objects returned by the <xref:System.Globalization.CultureInfo.NumberFormat*>, <xref:System.Globalization.CultureInfo.DateTimeFormat*>, <xref:System.Globalization.CultureInfo.TextInfo*>, and <xref:System.Globalization.CultureInfo.Calendar*> properties are also copied. Consequently, the cloned <xref:System.Globalization.CultureInfo> object can modify its copied properties without affecting the original <xref:System.Globalization.CultureInfo> object.

## Examples
 The following code example shows that CultureInfo.Clone also clones the <xref:System.Globalization.DateTimeFormatInfo> and <xref:System.Globalization.NumberFormatInfo> instances associated with the <xref:System.Globalization.CultureInfo>.

## Remarks
 The <xref:System.Globalization.CultureInfo.CompareInfo> property returns a <xref:System.Globalization.CompareInfo> object that provides culture-specific information used in culture-sensitive sorting and string comparison operations.

 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

## Examples
 The following code example shows how to create a <xref:System.Globalization.CultureInfo> for Spanish (Spain) with the international sort and another <xref:System.Globalization.CultureInfo> with the traditional sort.

## Remarks
 The <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> method wraps a call to the <xref:System.Globalization.CultureInfo.%23ctor(System.String)> constructor.

> [!NOTE]
> For a list of predefined culture names on Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag.

 Cultures are grouped into three sets: the invariant culture, the neutral cultures, and the specific cultures. For more information, see the description of the <xref:System.Globalization.CultureInfo> class.

 If the culture identifier of the specific culture returned by this method matches the culture identifier of the current Windows culture, this method creates a <xref:System.Globalization.CultureInfo> object that uses the Windows culture overrides. The overrides include user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> object returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property and the <xref:System.Globalization.NumberFormatInfo> object returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. To instantiate a <xref:System.Globalization.CultureInfo> object that with default culture settings rather than user overrides, call the <xref:System.Globalization.CultureInfo.%23ctor(System.String,System.Boolean)> constructor with a value of `false` for the `useUserOverride` argument.

 Although the <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> method name includes the term "Specific", remember that culture data can change between versions, or due to custom cultures, or because of user overrides. Use the invariant culture or binary or fixed forms for saving data.

## Examples
 The following example retrieves an array of <xref:System.Globalization.CultureInfo> objects that represent neutral cultures from the <xref:System.Globalization.CultureInfo.GetCultures*> method and sorts the array. When it iterates the elements in the array, it passes the name of each neutral culture to the <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> method and displays the name of the specific culture returned by the method.

> [!NOTE]
> The example uses the `zh-CHS` and `zh-CHT` culture names. However, applications that target Windows Vista and later should use `zh-Hans` instead of `zh-CHS` and `zh-Hant` instead of zh-CHT. `zh-Hans` and `zh-Hant` represent the current standard and should be used unless you have a reason for using the older names.
>
> Note also that the results of the example may differ on an installation of Taiwanese Windows, where the input of a Chinese (Traditional) neutral culture (zh, zh-CHT, or zh-Hant) will return zh-TW.

The <xref:System.Globalization.CultureInfo> object that's returned by the <xref:System.Globalization.CultureInfo.CurrentCulture> property and its associated objects determines the default format for dates, times, numbers, and currency values, the sorting order of text, casing conventions, and string comparisons.

The current culture is a property of the executing thread. When you set this property to a <xref:System.Globalization.CultureInfo> object that represents a new culture, the value of the `Thread.CurrentThread.CurrentCulture` property also changes. However, we recommend that you always use the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property to retrieve and set the current culture.

The `CultureInfo` object that this property returns is read-only. That means you can't mutate the existing object, for example, by changing the `DateTimeFormat`. To change the date-time format or some other aspect of the current culture, create a new `CultureInfo` object and assign it to the property.

## How a thread's culture is determined

When a thread is started, its culture is initially determined as follows:

- By retrieving the culture that is specified by the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property in the application domain in which the thread is executing, if the property value is not `null`.

- If the thread is a thread pool thread that is executing a task-based asynchronous operation, its culture is determined by the culture of the calling thread. The following example changes the current culture to Portuguese (Brazil) and launches six tasks, each of which displays its thread ID, its task ID, and its current culture. Each of the tasks (and the threads) has inherited the culture of the calling thread.

  :::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentCulture/Async1.cs" id="Snippet14":::
  :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentCulture/Async1.vb" id="Snippet14":::

  For more information, see [Culture and task-based asynchronous operations](xref:System.Globalization.CultureInfo#culture-and-task-based-asynchronous-operations).

- By calling the `GetUserDefaultLocaleName` function on Windows or the `uloc_getDefault` function from [ICU](https://icu-project.org/), which currently calls the POSIX `setlocale` function with category `LC_MESSAGES`, on Unix-like systems.

Note that if you set a specific culture that is different from the system-installed culture or the user's preferred culture, and your application starts multiple threads, the current culture of those threads will be the culture that is returned by the `GetUserDefaultLocaleName` function, unless you assign a culture to the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property in the application domain in which the thread is executing.

For more information about how the culture of a thread is determined, see the "Culture and threads" section in the <xref:System.Globalization.CultureInfo> reference page.

## Get the current culture

The <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property is a per-thread setting; that is, each thread can have its own culture. You get the culture of the current thread by retrieving the value of the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property, as the following example illustrates.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentCulture/Get1.cs" id="Snippet5":::
:::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentCulture/Get1.vb" id="Snippet5":::

## Set the CurrentCulture property explicitly

To change the culture that's used by an existing thread, you set the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property to the new culture. The following example changes the current thread culture to Dutch (Netherlands).

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentCulture/changeculture11.cs" id="Snippet11":::

> [!NOTE]
> Changing the culture by using the <xref:System.Globalization.CultureInfo.CurrentCulture?displayProperty=nameWithType> property requires a <xref:System.Security.Permissions.SecurityPermission> permission with the <xref:System.Security.Permissions.SecurityPermissionFlag.ControlThread> value set. Manipulating threads is dangerous because of the security state associated with threads. Therefore, this permission should be given only to trustworthy code, and then only as necessary. You cannot change thread culture in semi-trusted code.

You can explicitly change the current thread culture to either a specific culture (such as French (Canada)) or a neutral culture (such as French). When a <xref:System.Globalization.CultureInfo> object represents a neutral culture, the values of <xref:System.Globalization.CultureInfo> properties such as <xref:System.Globalization.CultureInfo.Calendar>, <xref:System.Globalization.CultureInfo.CompareInfo*>, <xref:System.Globalization.CultureInfo.DateTimeFormat>, <xref:System.Globalization.CultureInfo.NumberFormat>, and <xref:System.Globalization.CultureInfo.TextInfo> reflect the specific culture that is associated with the neutral culture. For example, the dominant culture for the English neutral culture is English (United States); the dominant culture for the German culture is German (Germany). The following example illustrates the difference in formatting when the current culture is set to a specific culture, French (Canada), and a neutral culture, French.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentCulture/specific12.cs" id="Snippet12":::
:::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentCulture/specific12.vb" id="Snippet12":::

## The current culture and user overrides

Windows allows users to override the standard property values of the <xref:System.Globalization.CultureInfo> object and its associated objects by using **Regional and Language Options** in Control Panel. The <xref:System.Globalization.CultureInfo> object returned by the <xref:System.Globalization.CultureInfo.CurrentCulture> property reflects these user overrides in the following cases:

- If the current thread culture is set implicitly by the Windows `GetUserDefaultLocaleName` function.
- If the current thread culture defined by the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property corresponds to the current Windows system culture.
- If the current thread culture is set explicitly to a culture returned by the <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> method, and that culture corresponds to the current Windows system culture.
- If the current thread culture is set explicitly to a culture instantiated by the <xref:System.Globalization.CultureInfo.%23ctor(System.String)> constructor, and that culture corresponds to the current Windows system culture.

In some cases, particularly for server applications, setting the current culture to a <xref:System.Globalization.CultureInfo> object that reflects user overrides may be undesirable. Instead, you can set the current culture to a <xref:System.Globalization.CultureInfo> object that does not reflect user overrides in the following ways:

- By calling the <xref:System.Globalization.CultureInfo.%23ctor(System.String,System.Boolean)> constructor with a value of `false` for the `useUserOverride` argument.
- By calling the <xref:System.Globalization.CultureInfo.GetCultureInfo*> method, which returns a cached, read-only <xref:System.Globalization.CultureInfo> object.

The <xref:System.Globalization.CultureInfo.CurrentUICulture> property is a per-thread property. That is, each thread has its own current UI culture. This property is equivalent to retrieving or setting the <xref:System.Globalization.CultureInfo> object assigned to the `System.Threading.Thread.CurrentThread.CurrentUICulture` property. When a thread is started, its UI culture is initially determined as follows:

- By retrieving the culture that is specified by the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property in the application domain in which the thread is executing, if the property value is not `null`.

- If the thread is a thread-pool thread that's executing a task-based asynchronous operation, its UI culture is determined by the UI culture of the calling thread. The following example changes the current UI culture to Portuguese (Brazil) and launches six tasks, each of which displays its thread ID, its task ID, and its current UI culture. Each of the tasks (and the threads) has inherited the UI culture of the calling thread.

  :::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentUICulture/Async1.cs" id="Snippet14":::
  :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentUICulture/Async1.vb" id="Snippet14":::

  For more information, see [Culture and task-based asynchronous operations](xref:System.Globalization.CultureInfo#culture-and-task-based-asynchronous-operations).

- By calling the Windows `GetUserDefaultUILanguage` function.

To change the user interface culture used by a thread, set the <xref:System.Threading.Thread.CurrentUICulture?displayProperty=nameWithType> property to the new culture. If you explicitly change a thread's UI culture in this way, that change persists if the thread crosses application domain boundaries.

> [!NOTE]
> If you set the property value to a <xref:System.Globalization.CultureInfo> object that represents a new culture, the value of the `Thread.CurrentThread.CurrentCulture` property also changes.

## Get the current UI culture

The <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property is a per-thread setting; that is, each thread can have its own UI culture. You get the UI culture of the current thread by retrieving the value of the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property, as the following example illustrates.

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentUICulture/Get1.cs" id="Snippet5":::
:::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentUICulture/Get1.vb" id="Snippet5":::

You can also retrieve the value of the current thread's UI culture from the <xref:System.Threading.Thread.CurrentUICulture?displayProperty=nameWithType> property.

## Explicitly set the current UI culture

You can change the current UI culture by assigning a <xref:System.Globalization.CultureInfo> object that represents the new culture to the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property. The current UI culture can be set to either a specific culture (such as en-US or de-DE) or to a neutral culture (such as en or de). The following example sets the current UI culture to fr-FR or French (France).

:::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/CurrentUICulture/currentuiculture1.cs" id="Snippet1":::
:::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/CurrentUICulture/currentuiculture1.vb" id="Snippet1":::

In a multithreaded application, you can explicitly set the UI culture of any thread by assigning a <xref:System.Globalization.CultureInfo> object that represents that culture to the thread's <xref:System.Threading.Thread.CurrentUICulture?displayProperty=nameWithType> property. If the thread whose culture you want to set is the current thread, you can assign the new culture to the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property. When the UI culture of a thread is set explicitly, that thread retains the same culture even if it crosses application domain boundaries and executes code in another application domain.

## Implicitly set the current UI culture

When a thread, including the main application thread, is first created, by default its current UI culture is set as follows:

- By using the culture defined by the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property for the current application domain if the property value is not `null`.
- By using the system's default culture. On systems that use the Windows operating system, the common language runtime calls the Windows `GetUserDefaultUILanguage` function to set the current  UI culture. `GetUserDefaultUILanguage` returns the default UI culture set by the user. If the user has not set a default UI language, it returns the culture originally installed on the system.

If the thread crosses application boundaries and executes code in another application domain, its culture is determined in the same way as that of a newly created thread.

Note that if you set a specific UI culture that is different from the system-installed UI culture or the user's preferred UI culture, and your application starts multiple threads, the current UI culture of those threads will be the culture returned by the `GetUserDefaultUILanguage` function, unless you assign a culture to the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property in the application domain in which the thread is executing.

## Security considerations

Changing the culture of the current thread requires a <xref:System.Security.Permissions.SecurityPermission> permission with the <xref:System.Security.Permissions.SecurityPermissionFlag.ControlThread> value set.

> [!CAUTION]
> Manipulating threads is dangerous because of the security state associated with threads. Therefore, this permission should be given only to trustworthy code, and then only as necessary. You cannot change thread culture in semi-trusted code.

You might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 The value of the <xref:System.Globalization.CultureInfo.DateTimeFormat> property and the <xref:System.Globalization.CultureInfo.NumberFormat> property is not calculated until your application accesses the property. If the user can change the current culture to a new culture while the application is running and then the application accesses the <xref:System.Globalization.CultureInfo.DateTimeFormat*> or <xref:System.Globalization.CultureInfo.NumberFormat> property, the application retrieves the defaults for the new culture instead of the overrides for the original culture. To preserve the overrides for the original current culture, the application should access the <xref:System.Globalization.CultureInfo.DateTimeFormat*> and <xref:System.Globalization.CultureInfo.NumberFormat*> properties before changing the current culture.

## Remarks

The <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property enables an application to define the default culture of all threads.

> [!IMPORTANT]
> If you have not explicitly set the culture of any existing threads, setting the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property also changes the culture of these threads. You should always explicitly set the culture of your main application thread, and not rely on the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property to define the culture of the main application thread.

 Unless it is set explicitly, the value of the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> property is `null`, and the culture of threads that have not been assigned an explicit culture is defined by the default Windows system culture.

 For more information about cultures and threads, see the "Culture and threads" section in the <xref:System.Globalization.CultureInfo> reference page.

## Examples
 The following example illustrates the default behavior of .NET in defining the current culture of a new thread. At startup, the example sets the current culture and the current UI culture to French (France) on all systems except those on which the default system culture is already French (France). If the default system culture is already French (France), the code sets the current culture and the current UI culture to English (United States). It then calls the `DisplayRandomNumbers` routine, which generates three random numbers and displays them as currency values. Next, it creates a new thread, which also executes the `DisplayRandomNumbers` routine.

 :::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/DefaultThreadCurrentCulture/defaultculture1.cs" id="Snippet1":::
 :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/DefaultThreadCurrentCulture/defaultculture1.vb" id="Snippet1":::

 As the output from the example shows, when the example is run on a computer whose system culture is English (United States), the main thread displays its currency values using the formatting conventions of the French (France) culture. However, because the worker thread's culture is derived from the current Windows system culture rather than the application's current culture, the work thread displays its currency values using the formatting conventions of the English (United States) culture.

 The following example uses the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture> and <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> properties  to define the current culture and current UI culture of a new application thread. At startup, the example sets the current culture and the current UI culture to French (France) on all systems except those on which the default system culture is already French (France). If the default system culture is already French (France), it sets the current culture and the current UI culture to English (United States). It then calls the `DisplayRandomNumbers` routine, which generates three random numbers and displays them as currency values. Next, it creates a new thread, which also executes the `DisplayRandomNumbers` routine.

 :::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/DefaultThreadCurrentCulture/defaultculture2.cs" id="Snippet2":::
 :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/DefaultThreadCurrentCulture/defaultculture2.vb" id="Snippet2":::

 As the output from the example shows, when the example is run on a computer whose system culture is English (United States), both the main thread and the worker thread display their currency values using the formatting conventions of the French (France) culture.

## Remarks

The <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property lets you define the default UI culture of all threads.

> [!IMPORTANT]
> If you have not explicitly set the UI culture of any existing threads, setting the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property also changes the culture of these threads. You should always explicitly set the culture of your main application thread, and not rely on the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property to define the culture of the main application thread.

 Unless it is set explicitly, the value of the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture> property is `null`, and the current culture of all threads that have not been assigned an explicit culture is defined by the default Windows system culture.

 For more information about cultures and threads, see the "Culture and threads" section of <xref:System.Globalization.CultureInfo>.

## Examples
 The following example illustrates the default behavior of .NET in defining the current culture of a new thread. It uses English and Russian language resources. The following text file named GreetingStrings.txt contains the English language resources:

```txt
greeting =Hello again!
newGreeting=Hello!
```

 It is compiled to a binary .resources file named GreetingStrings.resources by using the [Resource File Generator](/dotnet/framework/tools/resgen-exe-resource-file-generator) with the following command.

```console
resgen greetingstrings.txt
```

 The following text file named GreetingStrings.ru-RU.txt contains the Russian language resources:

```txt
greeting=Еще раз привет!
newGreeting=Привет!
```

 It is compiled to a binary .resources file named GreetingStrings.ru-RU.resources by using the [Resource File Generator](/dotnet/framework/tools/resgen-exe-resource-file-generator) with the following command.

```console
resgen greetingstrings.ru-RU.txt
```

 The application code, which is shown below, resides in a file named Example1.vb or Example1.cs. It is compiled to an executable by using the following command for the Visual Basic compiler:

```console
vbc Example1.vb /resource:GreetingStrings.resources
```

 For the C# compiler, the command is similar:

```console
csc /resource:GreetingStrings.resources Example1.cs
```

 This creates an assembly that includes the example's executable code along with the resources for its fallback culture. You can also use the [Assembly Linker](/dotnet/framework/tools/al-exe-assembly-linker) to create the resource file for the Russian (Russia) culture with the following command:

```console
>al /embed:greetingstrings.ru-RU.resources /c:ru-RU /template:example1.exe /out:ru-RU\Example1.resources.dll
```

 At startup, the example sets the current culture and the current UI culture to Russian (Russia) on all systems except those on which the default system culture is already Russian (Russia). If the default system culture is already Russian (Russia), the code sets the current culture and the current UI culture to English (United States). It then calls the `ShowGreeting` routine, which displays a simple string the first time it is called and a slightly different string on subsequent method calls. Next, it creates a new thread, which also executes the `ShowGreeting` routine.

 :::code language="csharp" source="~/snippets/csharp/System.Globalization/CultureInfo/DefaultThreadCurrentUICulture/example1.cs" id="Snippet1":::
 :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/DefaultThreadCurrentUICulture/example1.vb" id="Snippet1":::

 As the output from the example shows, when the example is run on a computer whose system culture is English (United States), the main thread displays its initial string in Russian. However, because the worker thread's culture is derived from the current Windows system culture rather than the application's current culture, the worker thread displays its string in English.

 The following example uses the <xref:System.Globalization.CultureInfo.DefaultThreadCurrentCulture*> and <xref:System.Globalization.CultureInfo.DefaultThreadCurrentUICulture*> properties  to define the current culture and current UI culture of a new application thread.

 The example uses the same resources files as the previous example. The commands to compile and to embed the localized Russian language resources into a satellite assembly are also identical, except that the name of the executable assembly changes.

 At startup, the example sets the current culture and the current UI culture to Russian (Russia) on all systems except those on which the default system culture is already Russian (Russia). If the default system culture is already Russian (Russia), it sets the current culture and the current UI culture to English (United States). It then calls the `ShowGreeting` routine, which displays a simple string the first time it is called and a slightly different string on subsequent method calls. Next, it creates a new thread, which also executes the `ShowGreeting` routine.

 :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/DefaultThreadCurrentUICulture/example2.vb" id="Snippet2":::

 As the output from the example shows, when the example is run on a computer whose system culture is English (United States), both the main thread and the worker thread display their strings in the Russian language.

## Remarks
 This property represents the localized name of the <xref:System.Globalization.CultureInfo> object.

 Culture names may vary due to scripting or formatting conventions. You should use the returned name for display, and not attempt to parse it.

 If a custom culture is created by means of the <xref:System.Globalization.CultureAndRegionInfoBuilder> class, the <xref:System.Globalization.CultureInfo.DisplayName> property is initialized to the value of the <xref:System.Globalization.CultureInfo.NativeName> property.



## Examples
 The following code example displays several properties of the neutral cultures.

> [!NOTE]
> The example displays the `zh-CHS` and `zh-CHT` cultures with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of `zh-CHS` and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.

        <summary>Gets an alternate user interface culture suitable for console applications when the default graphic user interface culture is unsuitable.</summary>

        <remarks>
          <format type="text/markdown"><![CDATA[

## Remarks
 Languages such as Arabic, Hebrew, Urdu, and Syriac are based on bidirectional text. Windows applications, which have a graphical user interface, support bidirectional languages. However, console applications, which employ the text user interface of the operating system console, do not provide bidirectional support. Therefore, if you localize a console application to Arabic or Hebrew, your application displays unreadable text on the console screen.

 The user interface culture specifies the resources an application needs to support user input and output, and by default is the same as the operating system culture. For example, the <xref:System.Globalization.CultureInfo.CurrentUICulture?displayProperty=nameWithType> property returns an Arabic culture for an Arabic operating system. Use the <xref:System.Globalization.CultureInfo.GetConsoleFallbackUICulture*> method to retrieve a culture suitable for a console application user interface. After your application retrieves the fallback user interface culture, it should assign the culture to the current user interface culture of the current thread. For more information, see the "Explicitly Setting the Current UI Culture" section of the <xref:System.Globalization.CultureInfo.CurrentUICulture> property.

 The following are predefined cultures that have a different fallback user-interface culture name from the predefined culture name.

Your application can use <xref:System.Globalization.CultureAndRegionInfoBuilder> to create a replacement for a culture, and that culture can have a console fallback culture of your choosing.

## Examples
 The following code example displays the fallback user interface culture associated with a culture object.

## Remarks
 We recommend that you use the string overload of this method (<xref:System.Globalization.CultureInfo.GetCultureInfo(System.String)>), because locale names should be used instead of LCIDs. For custom locales, the locale name is required.

 If `culture` is the locale identifier of the current culture, the returned <xref:System.Globalization.CultureInfo> object does not reflect any user overrides.

> [!NOTE]
> LCIDs are being deprecated, and implementers are strongly encouraged to use newer versions of APIs that support BCP 47 locale names instead. Each LCID can be represented by a BCP 47 locale name, but the reverse is not true. The LCID range is restricted and unable to uniquely identify all the possible combinations of language and region.

## Remarks

For a list of predefined culture names on Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag.

 The <xref:System.Globalization.CultureInfo.GetCultureInfo*> method retrieves a cached, read-only <xref:System.Globalization.CultureInfo> object. It offers better performance than a corresponding call to the <xref:System.Globalization.CultureInfo.%23ctor(System.String)?displayProperty=nameWithType> constructor.

 If `name` is the name of the current culture, the returned <xref:System.Globalization.CultureInfo> object does not reflect any user overrides. This makes the method suitable for server applications or tools that do not have a real user account on the system and that need to load multiple cultures efficiently.

 If `name` is <xref:System.String.Empty?displayProperty=nameWithType>, the method returns the invariant culture. This is equivalent to retrieving the value of the <xref:System.Globalization.CultureInfo.InvariantCulture> property.

## Remarks

By default, when trying to create any culture and the underlying platform (Windows NLS or ICU) does not carry specific data for this culture, the platform will try constructing a culture with data from other cultures or some constant values.

Setting `predefinedOnly` to `true` will ensure a culture is created only if the platform has real data for that culture.

## Remarks
 For a list of predefined culture names on Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag.

 The <xref:System.Globalization.CultureInfo.GetCultureInfo*> method obtains a cached, read-only <xref:System.Globalization.CultureInfo> object. It offers better performance than a corresponding call to a <xref:System.Globalization.CultureInfo.%23ctor*> constructor. The method is used to create a culture similar to that specified by the `name` parameter, but with different sorting and casing rules.

 If `name` or `altName` is the name of the current culture, the returned objects do not reflect any user overrides. If `name` is <xref:System.String.Empty?displayProperty=nameWithType>, the method returns the invariant culture. This is equivalent to retrieving the value of the <xref:System.Globalization.CultureInfo.InvariantCulture> property. If `altName` is <xref:System.String.Empty?displayProperty=nameWithType>, the method uses the writing system and comparison rules specified by the invariant culture.

## Remarks

> [!NOTE]
> This method and the <xref:System.Globalization.CultureInfo.IetfLanguageTag> property are deprecated. Instead of using these APIs, we recommend using the <xref:System.Globalization.CultureInfo.%23ctor*> constructors, <xref:System.Globalization.CultureInfo.GetCultureInfo*?displayProperty=nameWithType>, and the <xref:System.Globalization.CultureInfo.Name> property. IETF tags and names are identical.

 The RFC 4646 standard that is maintained by the Internet Engineering Task Force (IETF) defines an IETF language tag, which provides a uniform means of identifying a language. The format of an IETF language tag is the same as the culture name returned by the <xref:System.Globalization.CultureInfo.Name> property, but does not identify a culture uniquely. Different cultures share the same IETF language tag if those cultures have identical linguistic characteristics. The linguistic characteristics of a culture are contained in the <xref:System.Globalization.TextInfo> object associated with a <xref:System.Globalization.CultureInfo> object.

 An IETF language tag consists of a mandatory language identifier, an optional script identifier, and an optional region identifier.

 Your applications should use the retrieved culture to control language-specific tasks, such as managing a spelling or grammar checker. Applications should not use the retrieved culture to control culture-specific tasks, such as sorting text or formatting times and dates.

 For more information, see [RFC 4646 - "Tags for Identifying Languages](https://datatracker.ietf.org/doc/html/rfc4646).

## Remarks
 The <xref:System.Globalization.CultureInfo.GetCultures*> method is most commonly called with the `types` parameter set to the following values:

- <xref:System.Globalization.CultureTypes.SpecificCultures>, which returns all specific cultures.

- <xref:System.Globalization.CultureTypes.NeutralCultures>, which returns all neutral cultures and the invariant culture.

- <xref:System.Globalization.CultureTypes.AllCultures>, which returns all neutral and specific cultures, cultures installed in the Windows system, and custom cultures created by the user.

- <xref:System.Globalization.CultureTypes.UserCustomCulture>, which returns all custom cultures, such as those registered by the <xref:System.Globalization.CultureAndRegionInfoBuilder> class. In versions of Windows before Windows 10, the <xref:System.Globalization.CultureTypes.UserCustomCulture> value applies to all user-defined custom cultures. Starting with Windows 10, it applies to system cultures that lack complete cultural data and that do not have a unique local identifier, as indicated by the <xref:System.Globalization.CultureInfo.LCID> property value. As a result, code such as the following will return different results when run on Windows 10 and on an earlier version of Windows.

     :::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/DisplayName/getcultures3.vb" id="Snippet2":::

## Examples
 The following code example displays several properties of the neutral cultures.

> [!NOTE]
> The example displays the `zh-CHS` and `zh-CHT` cultures with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of `zh-CHS` and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.

## Remarks
 <xref:System.Globalization.CultureInfo.GetFormat*> implements <xref:System.IFormatProvider.GetFormat*?displayProperty=nameWithType>.

 `NumberFormatInfo` provides the culture-specific numeric format used in conjunction with the Format methods in the base data types. `DateTimeFormatInfo` controls how the date and time values are formatted for a specific culture.

## Remarks

> [!NOTE]
> This property (and the <xref:System.Globalization.CultureInfo.GetCultureInfoByIetfLanguageTag*> method) is deprecated. Instead, you should use the <xref:System.Globalization.CultureInfo.Name?displayProperty=nameWithType> property. IETF tags and names are identical.

 The RFC 4646 standard that is maintained by the Internet Engineering Task Force (IETF) defines an IETF language tag, which provides a uniform means of identifying a language. The format of an IETF language tag is similar to the culture name returned by the <xref:System.Globalization.CultureInfo.Name> property, but does not identify a culture uniquely. That is, different cultures share the same IETF language tag if those cultures have identical linguistic characteristics. The linguistic characteristics of a culture are contained in the <xref:System.Globalization.TextInfo> object associated with a <xref:System.Globalization.CultureInfo> object.

 An IETF language tag consists of a mandatory language identifier, an optional script identifier, and an optional region identifier.

 For more information, see [RFC 4646, "Tags for Identifying Languages](https://datatracker.ietf.org/doc/html/rfc4646). For a list of subtags, see [The IANA Language Subtag Registry](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry).

        <value>The object that is culture-independent (invariant).</value>
        <remarks>
          <format type="text/markdown"><![CDATA[

The invariant culture is culture-insensitive; it's associated with the English language but not with any country/region. You specify the invariant culture by name by using an empty string ("") in the call to a <xref:System.Globalization.CultureInfo> instantiation method. This property, <xref:System.Globalization.CultureInfo.InvariantCulture?displayProperty=nameWithType>, also retrieves an instance of the invariant culture. It can be used in almost any method in the <xref:System.Globalization> namespace that requires a culture. The objects returned by properties such as <xref:System.Globalization.CultureInfo.CompareInfo>, <xref:System.Globalization.CultureInfo.DateTimeFormat>, and <xref:System.Globalization.CultureInfo.NumberFormat> also reflect the string comparison and formatting conventions of the invariant culture.

Unlike culture-sensitive data, which is subject to change by user customization or by updates to .NET or the operating system, invariant culture data is stable over time and across installed cultures and cannot be customized by users. This makes the invariant culture particularly useful for operations that require culture-independent results, such as formatting and parsing operations that persist formatted data, or sorting and ordering operations that require that data be displayed in a fixed order regardless of culture.

## String operations

You can use the invariant culture for culture-sensitive string operations that are not affected by the conventions of the current culture and that are consistent across cultures. For example, you may want sorted data to appear in a fixed order or apply a standard set of casing conventions to strings regardless of the current culture. To do this, you pass the <xref:System.Globalization.CultureInfo.InvariantCulture> object to a method that has a <xref:System.Globalization.CultureInfo> parameter, such as <xref:System.String.Compare(System.String,System.String,System.Boolean,System.Globalization.CultureInfo)> and <xref:System.String.ToUpper(System.Globalization.CultureInfo)>.

## Persisting data

The <xref:System.Globalization.CultureInfo.InvariantCulture> property can be used to persist data in a culture-independent format. This provides a known format that does not change and that can be used to serialize and deserialize data across cultures. After the data is deserialized, it can be formatted appropriately based on the cultural conventions of the current user.

For example, if you choose to persist date and time data in string form, you can pass the <xref:System.Globalization.CultureInfo.InvariantCulture> object to the <xref:System.DateTime.ToString(System.String,System.IFormatProvider)?displayProperty=nameWithType> or <xref:System.DateTimeOffset.ToString(System.IFormatProvider)?displayProperty=nameWithType> method to create the string, and you can pass the <xref:System.Globalization.CultureInfo.InvariantCulture> object to the <xref:System.DateTime.Parse(System.String,System.IFormatProvider)?displayProperty=nameWithType> or <xref:System.DateTimeOffset.Parse(System.String,System.IFormatProvider,System.Globalization.DateTimeStyles)?displayProperty=nameWithType> method to convert the string back to a date and time value. This technique ensures that the underlying date and time values do not change when the data is read or written by users from different cultures.

The following example uses the invariant culture to persist a <xref:System.DateTime> value as a string. It then parses the string and displays its value by using the formatting conventions of the French (France) and German (Germany) cultures.

:::code language="vb" source="~/snippets/visualbasic/System.Globalization/CultureInfo/InvariantCulture/persist1.vb" id="Snippet1":::

## Security decisions

If you are making a security decision (such as whether to allow access to a system resource) based on the result of a string comparison or a case change, you should not use the invariant culture. Instead, you should perform a case-sensitive or case-insensitive ordinal comparison by calling a method that includes a <xref:System.StringComparison> parameter and supplying either <xref:System.StringComparison.Ordinal?displayProperty=nameWithType> or <xref:System.StringComparison.OrdinalIgnoreCase?displayProperty=nameWithType> as an argument. Code that performs culture-sensitive string operations can cause security vulnerabilities if the current culture is changed or if the culture on the computer that is running the code differs from the culture that is used to test the code. In contrast, an ordinal comparison depends solely on the binary value of the compared characters.

## Remarks
 A neutral culture is a culture that is associated with a language but not with a country or region. It differs from a specific culture, which is a culture that is associated with both a language and a country or region. For example, fr is the name for the neutral French culture, while fr-FR is the name for the French culture in France.

 If this property returns `false`, the culture is either a specific culture or the invariant culture.



## Examples
 The following code example determines which cultures using the Chinese language are neutral cultures.

> [!NOTE]
> The example displays the older `zh-CHS` and `zh-CHT` culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of `zh-CHS` and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.

 If the <xref:System.Globalization.CultureInfo> is read-only, the <xref:System.Globalization.CultureInfo.DateTimeFormat*> and <xref:System.Globalization.CultureInfo.NumberFormat*> instances are also read-only.



## Examples
 The following code example shows that <xref:System.Globalization.CultureInfo.IsReadOnly*> also helps protect the <xref:System.Globalization.DateTimeFormatInfo> and <xref:System.Globalization.NumberFormatInfo> instances associated with the <xref:System.Globalization.CultureInfo>.

 The input locale identifier was formerly called the keyboard layout. An input locale identifier is a broader concept than a keyboard layout since it can also indicate a speech-to-text converter, an Input Method Editor (IME), or any other form of input.

## Remarks
 In most cases, the culture identifier is mapped to the corresponding NLS locale identifier.

 In versions of Windows prior to Windows 10, the locale identifier `LOCALE_CUSTOM_UNSPECIFIED` (0x1000, or 4096) is assigned to custom cultures created by the user. Starting with Windows 10, it is assigned to any culture that does not have a unique locale identifier and does not have complete system-provided data. As a result, code that iterates cultures and retrieves those with an <xref:System.Globalization.CultureInfo.LCID*> value of `LOCALE_CUSTOM_UNSPECIFIED` returns a larger subset of <xref:System.Globalization.CultureInfo> objects if run under Windows 10.

> [!NOTE]
> LCIDs are being deprecated, and implementers are strongly encouraged to use newer versions of APIs that support BCP 47 locale names instead. Each LCID can be represented by a BCP 47 locale name, but the reverse is not true. The LCID range is restricted and unable to uniquely identify all the possible combinations of language and region.

## Examples
 The following code example shows how to create a <xref:System.Globalization.CultureInfo> for Spanish (Spain) with the international sort order and another <xref:System.Globalization.CultureInfo> with the traditional sort order.

## Remarks

For a list of predefined culture names and identifiers that the <xref:System.Globalization.CultureInfo.Name> property can return on Windows systems, see the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47). In addition, starting with Windows 10, `name` can be any valid BCP-47 language tag. Note that culture names are subject to change, and that they also can reflect the names of custom cultures.

 The <xref:System.Globalization.CultureInfo.Name?displayProperty=nameWithType> property follows the naming standards provided in the <xref:System.Globalization.CultureInfo> class topic. It returns the short form of the culture name that excludes any indication of an alternate sort order. For example, if you instantiate a <xref:System.Globalization.CultureInfo> object by using the string "de-DE_phoneb" to reflect an alternate sort order, the <xref:System.Globalization.CultureInfo.Name> property returns "de-DE".

 To get the full name of the culture, you should use the <xref:System.Globalization.CultureInfo.DisplayName*>, <xref:System.Globalization.CultureInfo.EnglishName*>, or <xref:System.Globalization.CultureInfo.NativeName> property.



## Examples
 The following code example displays several properties of the neutral cultures.

> [!NOTE]
> The example displays the older `zh-CHS` and `zh-CHT` culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of `zh-CHS` and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.

You might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 The values of the <xref:System.Globalization.CultureInfo.DateTimeFormat> property and the <xref:System.Globalization.CultureInfo.NumberFormat> property are not calculated until the user accesses the property. If the user uses the Control Panel to change the current culture to a new culture while the application is running and then accesses the <xref:System.Globalization.CultureInfo.DateTimeFormat*> or <xref:System.Globalization.CultureInfo.NumberFormat> property, the application retrieves the defaults for the new culture. not the overrides for the original culture. To preserve the overrides for the original current culture, the application should access the <xref:System.Globalization.CultureInfo.DateTimeFormat*> and <xref:System.Globalization.CultureInfo.NumberFormat*> properties before changing the current culture.

## Remarks
 Your application changes the calendar used by the current <xref:System.Globalization.CultureInfo> by setting the <xref:System.Globalization.DateTimeFormatInfo.Calendar> property of <xref:System.Globalization.CultureInfo.DateTimeFormat*>, which is an instance of the <xref:System.Globalization.DateTimeFormatInfo> class. The new calendar must be one of the calendars listed in <xref:System.Globalization.CultureInfo.OptionalCalendars*>. <xref:System.Globalization.CultureInfo.DateTimeFormat*> also includes other properties that customize the date and time formatting associated with that <xref:System.Globalization.DateTimeFormatInfo.Calendar*>.

## Examples
 The following code example demonstrates how to determine the <xref:System.Globalization.GregorianCalendar> versions supported by the culture.

## Remarks
 The cultures have a hierarchy in which the parent of a specific culture is a neutral culture, the parent of a neutral culture is the <xref:System.Globalization.CultureInfo.InvariantCulture*>, and the parent of the <xref:System.Globalization.CultureInfo.InvariantCulture*> is the invariant culture itself. The parent culture encompasses only the set of information that is common among its children.

 If the resources for the specific culture are not available in the system, the resources for the neutral culture are used. If the resources for the neutral culture are not available, the resources embedded in the main assembly are used. For more information on the resource fallback process, see [Packaging and Deploying Resources](/dotnet/framework/resources/packaging-and-deploying-resources-in-desktop-apps).

## Examples
 The following code example determines the parent culture of each specific culture using the Chinese language.

> [!NOTE]
> The example displays the older `zh-CHS` and `zh-CHT` culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of `zh-CHS` and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.

 The following code example displays several properties of the neutral cultures.

> [!NOTE]
> The `zh-Hans` and `zh-Hant` names represent the current standard for Chinese cultures. Older applications might reference the legacy `zh-CHS` and `zh-CHT` culture names, but these should be replaced with `zh-Hans` and `zh-Hant` respectively in modern applications.

## Remarks
 This method overrides <xref:System.Object.ToString*?displayProperty=nameWithType>. It returns a normalized version of the culture name that is passed to the <xref:System.Globalization.CultureInfo.%23ctor(System.String)> or <xref:System.Globalization.CultureInfo.%23ctor(System.String,System.Boolean)> constructor or to the <xref:System.Globalization.CultureInfo.CreateSpecificCulture*> or <xref:System.Globalization.CultureInfo.GetCultureInfo(System.String)> method. It normalizes the result string by converting characters in *languagecode2* to lowercase and converting characters in *country/regioncode2* to uppercase if necessary.

 Predefined culture names on Windows systems are listed in the **Language tag** column in the [list of language/region names supported by Windows](https://learn.microsoft.com/openspecs/windows_protocols/ms-lcid/a9eac961-e77d-41a6-90a5-ce1a8b0cdb9c). Culture names follow the standard defined by [BCP 47](https://tools.ietf.org/html/bcp47).

          <format type="text/markdown"><![CDATA[

## Remarks
 For example, the two-letter abbreviation for English is "en". The <xref:System.Globalization.CultureInfo.TwoLetterISOLanguageName> property value for the invariant culture is "iv".

> [!NOTE]
> When communicating between processes or persisting data it is usually better to use the full <xref:System.Globalization.CultureInfo.Name*?displayProperty=nameWithType>. Using just the language can lose context and data.

 If ISO 639-1 does not define a two-letter language code for a particular culture, the <xref:System.Globalization.CultureInfo.TwoLetterISOLanguageName> property returns a string that consists of three or more letters. For more information, see the example.



## Examples
 The following example lists the cultures whose <xref:System.Globalization.CultureInfo.TwoLetterISOLanguageName> property does not consist of a two-letter language code.

## Remarks
 The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture.

 If <xref:System.Globalization.CultureInfo.UseUserOverride*> is `true` and the specified culture matches the current culture of Windows, the <xref:System.Globalization.CultureInfo> uses those overrides, including user settings for the properties of the <xref:System.Globalization.DateTimeFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat> property, and the properties of the <xref:System.Globalization.NumberFormatInfo> instance returned by the <xref:System.Globalization.CultureInfo.NumberFormat> property. If the user settings are incompatible with the culture associated with the <xref:System.Globalization.CultureInfo>, for example, if the selected calendar is not one of the <xref:System.Globalization.CultureInfo.OptionalCalendars*>, the results of the methods and the values of the properties are undefined.

 This property is set when the <xref:System.Globalization.CultureInfo> is created.
