    <summary>Exposes instance methods for creating, moving, and enumerating through directories and subdirectories. This class cannot be inherited.</summary>
    <remarks>
      <format type="text/markdown"><![CDATA[

## Remarks
 Use the <xref:System.IO.DirectoryInfo> class for typical operations such as copying, moving, renaming, creating, and deleting directories.

 If you are going to reuse an object several times, consider using the instance method of <xref:System.IO.DirectoryInfo> instead of the corresponding static methods of the <xref:System.IO.Directory> class, because a security check will not always be necessary.

> [!NOTE]
>  In members that accept a path as an input string, that path must be well-formed or an exception is raised. For example, if a path is fully qualified but begins with a space, the path is not trimmed in methods of the class. Therefore, the path is malformed and an exception is raised. Similarly, a path or a combination of paths cannot be fully qualified twice. For example, "c:\temp c:\windows" also raises an exception in most cases. Ensure that your paths are well-formed when using methods that accept a path string.

 In members that accept a path, the path can refer to a file or just a directory. The specified path can also refer to a relative path or a Universal Naming Convention (UNC) path for a server and share name. For example, all the following are acceptable paths:

-   "c:\\\MyDir\\\MyFile.txt" in C#, or "c:\MyDir\MyFile.txt" in Visual Basic.

-   "c:\\\MyDir" in C#, or "c:\MyDir" in Visual Basic.

-   "MyDir\\\MySubdir" in C#, or "MyDir\MySubDir" in Visual Basic.

-   "\\\\\\\MyServer\\\MyShare" in C#, or "\\\MyServer\MyShare" in Visual Basic.

 By default, full read/write access to new directories is granted to all users.

 For a list of common I/O tasks, see [Common I/O Tasks](/dotnet/standard/io/common-i-o-tasks).

## Remarks
 This constructor does not check if a directory exists. This constructor is a placeholder for a string that is used to access the disk in subsequent operations.

 The `path` parameter can be a file name, including a file on a Universal Naming Convention (UNC) share.

> [!CAUTION]
>  When you compile a set of characters with a particular cultural setting and retrieve those same characters with a different cultural setting, the characters might not be interpretable, and could cause an exception to be thrown.

## Examples
 The following example uses this constructor to create the specified directory and subdirectory, and demonstrates that a directory that contains subdirectories cannot be deleted.

## Remarks

 If the directory already exists, this method does nothing.

 If the directory did not exist before calling this method, then any cached attribute information about the directory will be flushed if the creation is successful.

 For a list of common I/O tasks, see [Common I/O Tasks](/dotnet/standard/io/common-i-o-tasks).

## Examples
 The following example checks whether a specified directory exists, creates the directory if it does not exist, and deletes the directory.

## Remarks
 Use this method overload to create a directory with access control, so there is no chance the directory can be accessed before security is applied.

 If the directory already exists, this method does nothing.

 For a list of common I/O tasks, see [Common I/O Tasks](/dotnet/standard/io/common-i-o-tasks).

> [!IMPORTANT]
> This method was ported to .NET Core 3.1 as an extension method of the `FileSystemAclExtensions` class as part of the `System.Security.AccessControl` assembly: <xref:System.IO.FileSystemAclExtensions.Create(System.IO.DirectoryInfo,System.Security.AccessControl.DirectorySecurity)>.

## Examples

The following code example creates a new directory inside the user's temporary folder with the specified directory security attributes:

```csharp
using System.IO;
using System.Security.AccessControl;
using System.Security.Principal;
namespace ConsoleApp
{
    class Program
    {
        static void Main()
        {
            DirectorySecurity security = new DirectorySecurity();
            SecurityIdentifier identity = new SecurityIdentifier(WellKnownSidType.BuiltinUsersSid, null);
            FileSystemAccessRule accessRule = new FileSystemAccessRule(identity, FileSystemRights.FullControl, AccessControlType.Allow);
            security.AddAccessRule(accessRule);
            string path = Path.Combine(Path.GetTempPath(), "directoryToCreate");
            DirectoryInfo dirInfo = new DirectoryInfo(path);
            dirInfo.Create(security);
        }
    }
}

 Any and all directories specified in `path` are created, unless some part of `path` is invalid. The `path` parameter specifies a directory path, not a file path. If the subdirectory already exists, this method does nothing.

 For a list of common I/O tasks, see [Common I/O Tasks](/dotnet/standard/io/common-i-o-tasks).


## Examples
 The following example demonstrates creating a subdirectory. In this example, the created directories are removed once created. Therefore, to test this sample, comment out the delete lines in the code.

## Remarks
 If the `DirectoryInfo` has no files or subdirectories, this method deletes the `DirectoryInfo` even if `recursive` is `false`. Attempting to delete a `DirectoryInfo` that is not empty when `recursive` is `false` throws an <xref:System.IO.IOException>.

## Remarks
 The <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A> and <xref:System.IO.DirectoryInfo.GetDirectories%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A>, you can start enumerating the collection of <xref:System.IO.DirectoryInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetDirectories%2A>, you must wait for the whole array of <xref:System.IO.DirectoryInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A> can be more efficient.

 This method pre-populates the values of the following <xref:System.IO.DirectoryInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

 The returned collection is not cached; each call to the <xref:System.Collections.Generic.IEnumerable%601.GetEnumerator%2A> method on  the collection will start a new enumeration.


## Examples
 The following example enumerates the subdirectories under the C:\Program Files directory and uses a LINQ query to return the names of all directories that were created before 2009 by checking the value of the <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A> property.

 If you only need the names of the subdirectories, use the static <xref:System.IO.Directory> class for better performance. For an example, see the <xref:System.IO.Directory.EnumerateDirectories%28System.String%29> method.

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 The <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A> and <xref:System.IO.DirectoryInfo.GetDirectories%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A>, you can start enumerating the collection of <xref:System.IO.DirectoryInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetDirectories%2A>, you must wait for the whole array of <xref:System.IO.DirectoryInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateDirectories%2A> can be more efficient.

 This method pre-populates the values of the following <xref:System.IO.DirectoryInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

 The returned collection is not cached; each call to the <xref:System.Collections.Generic.IEnumerable%601.GetEnumerator%2A> method on  the collection will start a new enumeration.

 The returned collection is not cached; each call to the <xref:System.Collections.Generic.IEnumerable%601.GetEnumerator%2A> method on the collection will start a new enumeration.


## Examples
 The following example enumerates the files under a specified directory and uses a LINQ query to return the names of all files that were created before 2009 by checking the value of the <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A> property.

 If you only need the names of the files, use the static <xref:System.IO.Directory> class for better performance. For an example, see the <xref:System.IO.Directory.EnumerateFiles%28System.String%29?displayProperty=nameWithType> method.

 [!code-vb[System.IO.DirectoryInfo.EnumFiles#1](~/samples/snippets/visualbasic/VS_Snippets_CLR_System/system.io.directoryinfo.enumfiles/vb/module1.vb#1)]

 The following example shows how to enumerate files in a directory by using different search options. The example assumes a directory that has files named log1.txt, log2.txt, test1.txt, test2.txt, test3.txt, and a subdirectory that has a file named SubFile.txt.

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 The <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> and <xref:System.IO.DirectoryInfo.GetFiles%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateFiles%2A>, you can start enumerating the collection of <xref:System.IO.FileInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetFiles%2A>, you must wait for the whole array of <xref:System.IO.FileInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> can be more efficient.

 This method pre-populates the values of the following <xref:System.IO.FileInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

-   <xref:System.IO.FileInfo.Length%2A>

 The returned collection is not cached; each call to the <xref:System.Collections.Generic.IEnumerable%601.GetEnumerator%2A> method on the collection will start a new enumeration.


## Examples
 The following example shows how to enumerate files in a directory by using different search options. The example assumes a directory that has files named log1.txt, log2.txt, test1.txt, test2.txt, test3.txt, and a subdirectory that has a file named SubFile.txt.

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 The <xref:System.IO.DirectoryInfo.EnumerateFileSystemInfos%2A> and <xref:System.IO.DirectoryInfo.GetFileSystemInfos%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateFileSystemInfos%2A>, you can start enumerating the collection of <xref:System.IO.FileSystemInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetFileSystemInfos%2A>, you must wait for the whole array of <xref:System.IO.FileSystemInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFileSystemInfos%2A> can be more efficient.

 This method pre-populates the values of the following <xref:System.IO.FileSystemInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

 The returned collection is not cached; each call to the <xref:System.Collections.Generic.IEnumerable%601.GetEnumerator%2A> method on the collection will start a new enumeration.

## Remarks
 The <xref:System.IO.DirectoryInfo.Exists%2A> property returns `false` if any error occurs while trying to determine if the specified file exists. This can occur in situations that raise exceptions such as passing a file name with invalid characters or too many characters, a failing or missing disk, or if the caller does not have permission to read the file.


## Examples
 The following example demonstrates a use of the `Exists` property in the context of copying a source directory to a target directory.

## Remarks
 Calling this method overload is equivalent to calling the <xref:System.IO.Directory.GetAccessControl%2A> method overload and specifying the access control sections <xref:System.Security.AccessControl.AccessControlSections.Access?displayProperty=nameWithType> &#124; <xref:System.Security.AccessControl.AccessControlSections.Owner?displayProperty=nameWithType> &#124; <xref:System.Security.AccessControl.AccessControlSections.Group?displayProperty=nameWithType> (<xref:System.Security.AccessControl.AccessControlSections.Access?displayProperty=nameWithType> `Or` <xref:System.Security.AccessControl.AccessControlSections.Owner?displayProperty=nameWithType> `Or` <xref:System.Security.AccessControl.AccessControlSections.Group?displayProperty=nameWithType> in Visual Basic).

 Use the <xref:System.IO.DirectoryInfo.GetAccessControl%2A> method to retrieve the access control list (ACL) entries for the current file.

 An ACL describes individuals and/or groups who have, or do not have, rights to specific actions on the given file or directory. For more information, see [How to: Add or Remove Access Control List Entries](/dotnet/standard/io/how-to-add-or-remove-access-control-list-entries).

## Examples
 The following example uses the <xref:System.IO.DirectoryInfo.GetAccessControl%2A> and <xref:System.IO.DirectoryInfo.SetAccessControl%2A> methods to add and then remove an access control list (ACL) entry from a directory.

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 This method pre-populates the values of the following <xref:System.IO.DirectoryInfo> properties:

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 If there are no subdirectories, or no subdirectories match the `searchPattern` parameter, this method returns an empty array.

 This method pre-populates the values of the following <xref:System.IO.DirectoryInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>


## Examples
 The following example lists all of the directories and files that begin with the letter "c" in "c:\\".

## Remarks
 The <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> and <xref:System.IO.DirectoryInfo.GetFiles%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateFiles%2A>, you can start enumerating the collection of <xref:System.IO.FileInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetFiles%2A>, you must wait for the whole array of <xref:System.IO.FileInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> can be more efficient.

 If there are no files in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 The order of the returned file names is not guaranteed; use the <xref:System.Array.Sort%2A> method if a specific sort order is required.

 This method pre-populates the values of the following <xref:System.IO.FileInfo> properties:

 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 The <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> and <xref:System.IO.DirectoryInfo.GetFiles%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateFiles%2A>, you can start enumerating the collection of <xref:System.IO.FileInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetFiles%2A>, you must wait for the whole array of <xref:System.IO.FileInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> can be more efficient.

 If there are no files in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 The following wildcard specifiers are permitted in the `searchPattern` parameter.

|Wildcard character|Description|
|------------------------|-----------------|
|*|Zero or more characters.|
|?|Exactly zero or one character.|

 The order of the returned file names is not guaranteed; use the <xref:System.Array.Sort%2A> method if a specific sort order is required.

 Wildcards are permitted. For example, the `searchPattern` string "*.txt" searches for all file names having an extension of "txt". The `searchPattern` string "s\*" searches for all file names beginning with the letter "s". If there are no files, or no files that match the `searchPattern` string in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

> [!NOTE]
>  When using the asterisk wildcard character in a `searchPattern` (for example, "*.txt"), the matching behavior varies depending on the length of the specified file extension. A `searchPattern` with a file extension of exactly three characters returns files with an extension of three or more characters, where the first three characters match the file extension specified in the `searchPattern`. A `searchPattern` with a file extension of one, two, or more than three characters returns only files with extensions of exactly that length that match the file extension specified in the `searchPattern`. When using the question mark wildcard character, this method returns only files that match the specified file extension. For example, given two files in a directory, "file1.txt" and "file1.txtother", a search pattern of "file?.txt" returns only the first file, while a search pattern of "file\*.txt" returns both files.

> [!NOTE]
>  Because this method checks against file names with both the 8.3 file name format and the long file name format, a search pattern similar to "*1\*.txt" may return unexpected file names. For example, using a search pattern of "\*1\*.txt" will return "longfilename.txt" because the equivalent 8.3 file name format would be "longf~1.txt".

 This method pre-populates the values of the following <xref:System.IO.FileInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> can be more efficient.

 If there are no files in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 The following wildcard specifiers are permitted in the `searchPattern` parameter.

|Wildcard character|Description|
|------------------------|-----------------|
|*|Zero or more characters.|
|?|Exactly zero or one character.|

 The order of the returned file names is not guaranteed; use the <xref:System.Array.Sort%2A> method if a specific sort order is required.

 Wildcards are permitted. For example, the `searchPattern` string "*.txt" searches for all file names having an extension of "txt". The `searchPattern` string "s\*" searches for all file names beginning with the letter "s". If there are no files, or no files that match the `searchPattern` string in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

> [!NOTE]
>  When using the asterisk wildcard character in a `searchPattern` (for example, "*.txt"), the matching behavior varies depending on the length of the specified file extension. A `searchPattern` with a file extension of exactly three characters returns files with an extension of three or more characters, where the first three characters match the file extension specified in the `searchPattern`. A `searchPattern` with a file extension of one, two, or more than three characters returns only files with extensions of exactly that length that match the file extension specified in the `searchPattern`. When using the question mark wildcard character, this method returns only files that match the specified file extension. For example, given two files in a directory, "file1.txt" and "file1.txtother", a search pattern of "file?.txt" returns only the first file, while a search pattern of "file\*.txt" returns both files.

> [!NOTE]
>  Because this method checks against file names with both the 8.3 file name format and the long file name format, a search pattern similar to "*1\*.txt" may return unexpected file names. For example, using a search pattern of "\*1\*.txt" will return "longfilename.txt" because the equivalent 8.3 file name format would be "longf~1.txt".

 This method pre-populates the values of the following <xref:System.IO.FileInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

## Remarks
 The <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> and <xref:System.IO.DirectoryInfo.GetFiles%2A> methods differ as follows:

-   When you use <xref:System.IO.DirectoryInfo.EnumerateFiles%2A>, you can start enumerating the collection of <xref:System.IO.FileInfo> objects before the whole collection is returned.

-   When you use <xref:System.IO.DirectoryInfo.GetFiles%2A>, you must wait for the whole array of <xref:System.IO.FileInfo> objects to be returned before you can access the array.

 Therefore, when you are working with many files and directories, <xref:System.IO.DirectoryInfo.EnumerateFiles%2A> can be more efficient.

 If there are no files in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard character|Description|
|------------------------|-----------------|
|\* (asterisk)|Zero or more characters.|
|? (question mark)|Exactly zero or one character.|

 The order of the returned file names is not guaranteed; use the <xref:System.Array.Sort%2A> method if a specific sort order is required.

 Wildcards are permitted. For example, the `searchPattern` string "*.txt" searches for all file names having an extension of "txt". The `searchPattern` string "s\*" searches for all file names beginning with the letter "s". If there are no files, or no files that match the `searchPattern` string in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

> [!NOTE]
>  When using the asterisk wildcard character in a `searchPattern` (for example, "*.txt"), the matching behavior varies depending on the length of the specified file extension. A `searchPattern` with a file extension of exactly three characters returns files with an extension of three or more characters, where the first three characters match the file extension specified in the `searchPattern`. A `searchPattern` with a file extension of one, two, or more than three characters returns only files with extensions of exactly that length that match the file extension specified in the `searchPattern`. When using the question mark wildcard character, this method returns only files that match the specified file extension. For example, given two files in a directory, "file1.txt" and "file1.txtother", a search pattern of "file?.txt" returns only the first file, while a search pattern of "file\*.txt" returns both files.

 The following list shows the behavior of different lengths for the `searchPattern` parameter:

-   "*.abc" returns files having an extension of.abc,.abcd,.abcde,.abcdef, and so on.

-   "*.abcd" returns only files having an extension of.abcd.

-   "*.abcde" returns only files having an extension of.abcde.

-   "*.abcdef" returns only files having an extension of.abcdef.

> [!NOTE]
>  Because this method checks against file names with both the 8.3 file name format and the long file name format, a search pattern similar to "*1\*.txt" may return unexpected file names. For example, using a search pattern of "\*1\*.txt" will return "longfilename.txt" because the equivalent 8.3 file name format would be "longf~1.txt".

 This method pre-populates the values of the following <xref:System.IO.FileInfo> properties:

1.  <xref:System.IO.FileSystemInfo.Attributes%2A>

2.  <xref:System.IO.FileSystemInfo.CreationTime%2A>

7.  <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>

8.  <xref:System.IO.FileInfo.Length%2A>


## Examples
 The following example shows how to get a list of files from a directory by using different search options. The example assumes a directory that has files named log1.txt, log2.txt, test1.txt, test2.txt, test3.txt, and a subdirectory that has a file named SubFile.txt.

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 This method is not recursive.

 For subdirectories, the <xref:System.IO.FileSystemInfo> objects returned by this method can be cast to the derived class <xref:System.IO.DirectoryInfo>. Use the <xref:System.IO.FileAttributes> value returned by the <xref:System.IO.FileSystemInfo.Attributes%2A?displayProperty=nameWithType> property to determine whether the <xref:System.IO.FileSystemInfo> represents a file or a directory.

 Wild cards are permitted. For example, the `searchPattern` string "\*t" searches for all directory names in `path` ending with the letter "t". The `searchPattern` string "s\*" searches for all directory names in `path` beginning with the letter "s".

 The string ".." can only be used in `searchPattern` if it is specified as a part of a valid directory name, such as in the directory name "a..b". It cannot be used to move up the directory hierarchy. If there are no files or directories, or no files or directories that match the `searchPattern` string in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 This method pre-populates the values of the following <xref:System.IO.FileSystemInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTime%2A>

-   <xref:System.IO.FileSystemInfo.LastWriteTimeUtc%2A>


## Examples

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 This method is not recursive.

 For subdirectories, the <xref:System.IO.FileSystemInfo> objects returned by this method can be cast to the derived class <xref:System.IO.DirectoryInfo>. Use the <xref:System.IO.FileAttributes> value returned by the <xref:System.IO.FileSystemInfo.Attributes%2A?displayProperty=nameWithType> property to determine whether the <xref:System.IO.FileSystemInfo> represents a file or a directory.

 Wild cards are permitted. For example, the `searchPattern` string "\*t" searches for all directory names in `path` ending with the letter "t". The `searchPattern` string "s\*" searches for all directory names in `path` beginning with the letter "s".

 The string ".." can only be used in `searchPattern` if it is specified as a part of a valid directory name, such as in the directory name "a..b". It cannot be used to move up the directory hierarchy. If there are no files or directories, or no files or directories that match the `searchPattern` string in the <xref:System.IO.DirectoryInfo>, this method returns an empty array.

 This method pre-populates the values of the following <xref:System.IO.FileSystemInfo> properties:

-   <xref:System.IO.FileSystemInfo.Attributes%2A>

-   <xref:System.IO.FileSystemInfo.CreationTime%2A>

-   <xref:System.IO.FileSystemInfo.CreationTimeUtc%2A>

-   <xref:System.IO.FileSystemInfo.LastAccessTime%2A>

## Remarks
 `searchPattern` can be a combination of literal and wildcard characters, but it doesn't support regular expressions. The following wildcard specifiers are permitted in `searchPattern`.

|Wildcard specifier|Matches|
|------------------------|-------------|
|\* (asterisk)|Zero or more characters in that position.|
|? (question mark)|Zero or one character in that position.|

 Characters other than the wildcard are literal characters. For example, the string "\*t" searches for all names in  ending with the letter "t". ". The `searchPattern` string "s\*" searches for all names in `path` beginning with the letter "s".

 For subdirectories, the <xref:System.IO.FileSystemInfo> objects returned by this method can be cast to the derived class <xref:System.IO.DirectoryInfo>. Use the <xref:System.IO.FileAttributes> value returned by the <xref:System.IO.FileSystemInfo.Attributes%2A?displayProperty=nameWithType> property to determine whether the <xref:System.IO.FileSystemInfo> represents a file or a directory.

 This method pre-populates the values of the following <xref:System.IO.FileSystemInfo> properties:

## Remarks
 This method throws an <xref:System.IO.IOException> if, for example, you try to move c:\mydir to c:\public, and c:\public already exists. You must specify "c:\\\public\\\mydir" as the `destDirName` parameter, or specify a new directory name such as "c:\\\newdir".

 This method permits moving a directory to a read-only directory. The read/write attribute of neither directory is affected.

## Remarks
 This <xref:System.IO.DirectoryInfo.Name%2A> property returns only the name of the directory, such as "Bin". To get the full path, such as "c:\public\Bin", use the <xref:System.IO.FileSystemInfo.FullName%2A> property.

 The <xref:System.IO.DirectoryInfo.Name%2A> property of a <xref:System.IO.DirectoryInfo> requires no permission (beyond the read permission to the directory necessary to construct the <xref:System.IO.DirectoryInfo.Exists%2A>) but can give out the directory name. If it is necessary to hand out a <xref:System.IO.DirectoryInfo> to a protected directory with a cryptographically secure name, create a dummy directory for the untrusted code's use.

 For a list of common I/O tasks, see [Common I/O Tasks](/dotnet/standard/io/common-i-o-tasks).

 The following example displays the name of the current `DirectoryInfo` instance only.

## Remarks

> [!IMPORTANT]
> In .NET Framework, `Parent` returns a relative path.
> In .NET Core, `Parent` returns a fully qualified path.

To ensure consistent behavior across versions and to make your intent explicit, retrieve the value of one of the following properties on the <xref:System.IO.DirectoryInfo> instance returned by `Parent`.
- <xref:System.IO.DirectoryInfo.Name>, which returns the simple name of the directory (such as `bin`).
- <xref:System.IO.DirectoryInfo.FullName>, which returns the absolute path of the directory.

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

## Remarks
 An access control list (ACL) describes individuals and/or groups who have, or do not have, rights to specific actions on the given file or directory. For more information, see [How to: Add or Remove Access Control List Entries](/dotnet/standard/io/how-to-add-or-remove-access-control-list-entries).

 The <xref:System.IO.DirectoryInfo.SetAccessControl%2A> method applies ACL entries to a file that represents the noninherited ACL list.

> [!CAUTION]
>  The ACL specified for `directorySecurity` replaces the existing ACL for the directory. To add permissions for a new user, use the <xref:System.IO.DirectoryInfo.GetAccessControl%2A> method to obtain the existing ACL, and modify it.

 The <xref:System.IO.DirectoryInfo.SetAccessControl%2A> method persists only <xref:System.Security.AccessControl.DirectorySecurity> objects that have been modified after object creation.  If a <xref:System.Security.AccessControl.DirectorySecurity> object has not been modified, it will not be persisted to a file.  Therefore, it is not possible to retrieve a <xref:System.Security.AccessControl.DirectorySecurity> object from one file and reapply the same object to another file.

 To copy ACL information from one file to another:

1.  Use the <xref:System.IO.DirectoryInfo.GetAccessControl%2A> method to retrieve the <xref:System.Security.AccessControl.DirectorySecurity> object from the source file.

2.  Create a new <xref:System.Security.AccessControl.DirectorySecurity> object for the destination file.

3.  Use the <xref:System.Security.AccessControl.ObjectSecurity.GetSecurityDescriptorBinaryForm%2A> or <xref:System.Security.AccessControl.ObjectSecurity.GetSecurityDescriptorSddlForm%2A> method of the source <xref:System.Security.AccessControl.DirectorySecurity> object to retrieve the ACL information.

4.  Use the <xref:System.Security.AccessControl.ObjectSecurity.SetSecurityDescriptorBinaryForm%2A> or <xref:System.Security.AccessControl.ObjectSecurity.SetSecurityDescriptorSddlForm%2A> method to copy the information retrieved in step 3 to the destination <xref:System.Security.AccessControl.DirectorySecurity> object.

5.  Set the destination <xref:System.Security.AccessControl.DirectorySecurity> object to the destination file using the <xref:System.IO.DirectoryInfo.SetAccessControl%2A> method.


## Examples
 The following example uses the <xref:System.IO.DirectoryInfo.GetAccessControl%2A> and <xref:System.IO.DirectoryInfo.SetAccessControl%2A> methods to add and then remove an access control list (ACL) entry from a directory.

> - <xref:System.IO.DirectoryInfo.FullName>, to get the fully qualified path of the directory.
