## Remarks
 ASP.NET uses the <xref:System.Web.Profile.ProfileBase> class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type `ProfileCommon`, which inherits from the <xref:System.Web.Profile.ProfileBase> class. Strongly typed accessors are added to the `ProfileCommon` class for each property defined in the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration section. The strongly typed accessors of the `ProfileCommon` class call the <xref:System.Web.Profile.ProfileBase.GetPropertyValue%2A> and <xref:System.Web.Profile.ProfileBase.SetPropertyValue%2A> methods of the <xref:System.Web.Profile.ProfileBase> base class to retrieve and set profile property values, respectively. An instance of the `ProfileCommon` class is set as the value of the <xref:System.Web.HttpContext.Profile%2A> property for the ASP.NET application.

 To create an instance of a user profile in an ASP.NET application, it is recommended that you use the <xref:System.Web.Profile.ProfileBase.Create%2A> method.

## Notes to Inheritors

You can create a custom profile implementation that inherits from the <xref:System.Web.Profile.ProfileBase> abstract class and defines properties for the user profile that are not specified in the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration element. You can specify a custom user-profile type in the web.config file with the `inherits` attribute of the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration element, as shown in the following example. The code for the `EmployeeProfile` class is included in the Example section of this topic.

:::code language="xml" source="~/snippets/csharp/VS_Snippets_WebNet/System.Web.Profile.HttpProfileBase/CS/config.xml":::

## Examples
 The following code example shows a Web.config file that specifies a user profile that contains a `ZipCode` property of type `string` and a `RecentSearchList` property of type <xref:System.Collections.Specialized.StringCollection>. The generated <xref:System.Web.HttpContext.Profile%2A> property of the current <xref:System.Web.HttpContext> will have strongly typed accessors for each of the specified properties.

```xml
<configuration>
  <system.web>
    <anonymousIdentification enabled="true" />

    <profile enabled="true" defaultProvider="SqlProvider" >
      <properties>
        <add name="ZipCode" allowAnonymous="true" />
        <add name="RecentSearchList"
          type="System.Collections.Specialized.StringCollection"
          serializeAs="Xml"
          allowAnonymous="true" />
      </properties>
    </profile>
  </system.web>
</configuration>
```

 The following example shows an ASP.NET page that reads and sets the `ZipCode` property specified for the user profile. Before attempting to run this code, set the provider to the default `AspNetSqlProvider` in the ASP.NET configuration settings for the Web site.

 :::code language="aspx-vb" source="~/snippets/visualbasic/VS_Snippets_WebNet/System.Web.Profile.HttpProfileBase/VB/defaultvb.aspx" id="Snippet1":::

 The following code example defines a class that inherits from the <xref:System.Web.Profile.ProfileBase> class to create a custom profile. The type of the custom profile is specified in the `inherits` attribute of the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration element in the Web.config file for an application.

## Remarks
 ASP.NET uses the <xref:System.Web.Profile.ProfileBase> class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type `ProfileCommon`, which inherits from the <xref:System.Web.Profile.ProfileBase> class. Strongly typed accessors are added to the `ProfileCommon` class for each property defined in the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration section. The strongly typed accessors of the `ProfileCommon` class call the <xref:System.Web.Profile.ProfileBase.GetPropertyValue%2A> and <xref:System.Web.Profile.ProfileBase.SetPropertyValue%2A> methods of the <xref:System.Web.Profile.ProfileBase> base class to retrieve and set profile property values, respectively. An instance of the `ProfileCommon` class is set as the value of the <xref:System.Web.HttpContext.Profile%2A> property for the ASP.NET application.

> [!NOTE]
>  The base class used to generate the class stored in the <xref:System.Web.HttpContext.Profile%2A> property can be overridden using the `inherits` attribute of the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) section of the configuration file. In this case you would specify a custom class that inherits from the <xref:System.Web.Profile.ProfileBase> base class.

 This constructor is not intended to be used from application code. To create an instance of a user profile, use the <xref:System.Web.Profile.ProfileBase.Create%2A> method.



## Examples
 The following Web.config file specifies a user profile that contains a `ZipCode` property of type `string` and a `RecentSearchList` property of type <xref:System.Collections.Specialized.StringCollection>. The generated <xref:System.Web.HttpContext.Profile%2A> property of the current <xref:System.Web.HttpContext> will have strongly typed accessors for each of the specified properties.

```xml
<configuration>
   <connectionStrings>
       <add name="SqlServices" connectionString="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
   </connectionStrings>

  <system.web>
   <anonymousIdentification enabled="true" />

   <profile defaultProvider="SqlProvider" >
     <providers>
       <add
         name="SqlProvider"
         connectionStringName="SqlServices"
         applicationName="ProfileBaseApplication"
         type="System.Web.Profile.SqlProfileProvider" />
     </providers>

     <properties>
       <add name="ZipCode" allowAnonymous="true" />
       <add name="RecentSearchList"
            type="System.Collections.Specialized.StringCollection"
            serializeAs="Xml"
            allowAnonymous="true" />
      </properties>
    </profile>
   </system.web>
</configuration>
```

 The following ASP.NET page reads and sets the `ZipCode` property specified for the user profile.

The <xref:System.Web.Profile.ProfileBase.GetProfileGroup%2A> property can be used to retrieve a group of properties by the group name. You can also access a profile property in a group by specifying the group name as a member of the `Profile` property available on each page. For example, the `ZipCode` profile property that is a member of the `Address` profile group could be accessed using `Profile.Address.ZipCode`.



## Examples
 The following Web.config file specifies a user profile that contains group of properties with a group name of `Address`. The grouped properties generated for the <xref:System.Web.HttpContext.Profile%2A> property of the current <xref:System.Web.HttpContext> will be preceded by the group name. For example, `Profile.Address.Street`.

```xml
<configuration>
  <connectionStrings>
    <add name="SqlServices" connectionString=
      "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
  </connectionStrings>

  <system.web>

          passwordFormat="Hashed"
          applicationName="MyApplication" />
      </providers>
    </membership>

    <profile defaultProvider="SqlProvider">
      <providers>
        <add
          name="SqlProvider"
          connectionStringName="SqlServices"
          applicationName="MyApplication"
          type="System.Web.Profile.SqlProfileProvider" />

      </providers>

      <properties>
        <add name="ZipCode" />
        <group name="Address">

          <add name="City" />
          <add name="State" />
          <add name="CountryOrRegion" />
        </group>
      </properties>
    </profile>
  </system.web>
</configuration>
```

 The following ASP.NET page reads and sets the grouped properties specified for the user profile.

## Remarks
 ASP.NET uses the <xref:System.Web.Profile.ProfileBase> class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type `ProfileCommon`, which inherits from the <xref:System.Web.Profile.ProfileBase> class. Strongly typed accessors are added to the `ProfileCommon` class for each property defined in the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration section. The strongly typed accessors of the `ProfileCommon` class call the <xref:System.Web.Profile.ProfileBase.GetPropertyValue%2A> method to retrieve untyped values from the <xref:System.Web.Profile.ProfileProvider> that the generated accessor then casts as the specified type and returns as the property value.

 You can use the <xref:System.Web.Profile.ProfileBase.GetPropertyValue%2A> method to retrieve property values of the user profile for your application by name. Returned values are untyped and must be cast as the specific object type when retrieved. For strongly typed access to profile property values, you can access the property by name as a member of the Profile property available on each page, for example, `Profile.CustomerAddress`.



## Examples
 The following code example shows an ASP.NET page that reads and sets the `ZipCode` property specified for the user profile. For an example of a Web.config file that specifies properties for the user profile, see the example provided for the <xref:System.Web.Profile.ProfileBase> class.

## Remarks
 The <xref:System.Web.Profile.ProfileBase.IsDirty%2A> property can be used by a profile provider during the <xref:System.Configuration.SettingsBase.Save%2A> method to determine whether properties that are made up of primitive types, strings, or <xref:System.DateTime> objects have been changed. Changed properties are then updated by the profile provider in the <xref:System.Configuration.SettingsBase.Save%2A> method. The <xref:System.Configuration.SettingsBase.Save%2A> method is automatically called at the end of page execution if the <xref:System.Web.Profile.ProfileManager.AutomaticSaveEnabled%2A> property is `true`

 A profile provider called in the <xref:System.Configuration.SettingsBase.Save%2A> method cannot explicitly determine whether a profile property with a custom class type or a complex type, such as a collection, has changed. You can use the <xref:System.Web.Profile.ProfileModule.ProfileAutoSaving> event to determine whether a custom object has been modified and to continue with the automatic save for modified objects or cancel the automatic save if no objects have been modified. The default behavior of the <xref:System.Web.Profile.ProfileBase> class is to set the <xref:System.Web.Profile.ProfileBase.IsDirty%2A> property to `true` for properties that are of a custom or complex type the first time the property is accessed.

## Remarks
 You can use this property to retrieve or set the property values of the user profile for your application by name. Returned values are typed as `object` and must be cast as the specific object type when retrieved. For strongly typed access to profile property values, you can access the property by name as a member of the `Profile` property available on each page, for example, `Profile.CustomerAddress`.



## Examples
 The following code example lists the names of the properties in the user profile by binding the <xref:System.Configuration.SettingsProperty.Name%2A> property from the static <xref:System.Web.Profile.ProfileBase.Properties%2A> collection of <xref:System.Configuration.SettingsProperty> objects to a <xref:System.Web.UI.WebControls.GridView> control. The selected property value is retrieved by name using the <xref:System.Web.Profile.ProfileBase.Item%2A> collection. For an example of a Web.config file that specifies properties for the user profile, see the example provided for the <xref:System.Web.Profile.ProfileBase> class.

## Remarks
 You can use this property to get information about the profile properties configured for an application, including property names and types. You can also reference the <xref:System.Web.Profile.ProfileProvider> of each property. A <xref:System.Web.Profile.ProfileProvider> manages storage and retrieval of property values to and from the data source.



## Examples
 The following code example lists the names of the properties in the user profile by binding the <xref:System.Configuration.SettingsProperty.Name%2A> property from the static <xref:System.Web.Profile.ProfileBase.Properties%2A> collection of <xref:System.Configuration.SettingsProperty> objects to a <xref:System.Web.UI.WebControls.GridView> control. The selected property value is retrieved by name using the <xref:System.Web.Profile.ProfileBase.Item%2A> collection. For an example of a Web.config file that specifies properties for the user profile, see the example provided for the <xref:System.Web.Profile.ProfileBase> class.

## Remarks
 The <xref:System.Web.Profile.ProfileBase.Save%2A> method writes modified profile property values to the data source. The profile provider can reduce the amount of activity at the data source by performing updates only when the <xref:System.Web.Profile.ProfileBase.IsDirty%2A> property is set to `true`. This is the case for the default <xref:System.Web.Profile.SqlProfileProvider>. After the <xref:System.Web.Profile.ProfileBase.Save%2A> method has saved the property values to the data source, <xref:System.Web.Profile.ProfileBase.IsDirty%2A> is set to `false`.

 You can use the <xref:System.Web.Profile.ProfileModule.ProfileAutoSaving> event to implement custom logic that determines whether a profile property with a custom type or a complex type has been modified and continue with the automatic save for modified objects or cancel the automatic save if no objects have been modified.

## Remarks
 ASP.NET uses the <xref:System.Web.Profile.ProfileBase> class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type `ProfileCommon`, which inherits from the <xref:System.Web.Profile.ProfileBase> class. Strongly typed accessors are added to the `ProfileCommon` class for each property defined in the [profile](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164644(v%3dvs.100)) configuration section. The strongly typed accessors of the `ProfileCommon` class call the <xref:System.Web.Profile.ProfileBase.SetPropertyValue%2A> method to pass property values to the <xref:System.Web.Profile.ProfileProvider> to be stored at the data source.

 You can use the <xref:System.Web.Profile.ProfileBase.SetPropertyValue%2A> method to assign property values in the user profile for your application by name. Values are untyped, and type checking will be done at run time, not compile time. For strongly typed access to profile property values, you can access the property by name as a member of the `Profile` property that is available on each page, for example, `Profile.CustomerAddress`.



## Examples
 The following code example shows an ASP.NET page that reads and sets the `ZipCode` property specified for the user profile. For an example of a Web.config file that specifies properties for the user profile, see the example provided for the <xref:System.Web.Profile.ProfileBase> class.

> [!IMPORTANT]
>  This example contains a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see [Script Exploits Overview](https://docs.microsoft.com/previous-versions/aspnet/w1sw53ds(v=vs.100)).

## Remarks
 The <xref:System.Web.Profile.ProfileBase.UserName%2A> property returns either the name of the authenticated user that the profile is associated with or the anonymous user identifier assigned to the profile if the <xref:System.Web.Profile.ProfileBase.IsAnonymous%2A> property is `true`.

 Anonymous access to the user profile is enabled using the [anonymousIdentification](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/91ka2e6a(v%3dvs.100)) configuration section and the allowAnonymous attribute of the [add](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ms164646(v%3dvs.100)) configuration element used to specify profile properties.
