备注
LocalizationExtenderProvider 可以用一组属性和方法来扩展 IRootDesigner，这些属性和方法为 .NET Framework 本地化结构提供支持。有关使用资源的更多信息，请参见本地化。
本地化支持结构使设计器能够利用资源文件来初始化组件属性，这些资源文件可在运行时进行交换，从而支持各种语言、区域性特定的样式和动态配置功能。您可以使用此类的方法来使设计器和代码生成序列化程序从资源加载，并生成使用本地化功能的初始化代码。
Visual Studio 附带的默认序列化程序已经能够对组件和控件进行本地化，但它们仅在找到对 .NET Framework 本地化结构的支持时才进行本地化。若要检测是否存在本地化支持，序列化系统必须在根设计器组件上找到名为“Localizable”的公共 Boolean 属性。如果序列化程序找到此属性，它将搜索名为“Language”的 CultureInfo 类型的属性，以确定当前的资源配置。默认序列化程序使用这些属性来确定是否应对组件中的所有可本地化资源进行本地化，如果应该进行本地化，则还确定应以何种 CultureInfo 格式保存资源信息。
示例
下面的代码示例将一个 LocalizationExtenderProvider 添加到了一个组件中。
' Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = New LocalizationExtenderProvider(Me.component_.Site, Me.component_)
// Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = new LocalizationExtenderProvider(this.component.Site, this.component);
// Adds a LocalizationExtenderProvider that provides localization
// support properties to the specified component.
extender = new LocalizationExtenderProvider(
this.component.get_Site(), this.component);
下面的代码示例包含一个示例组件设计器。这个设计器使用 LocalizationExtenderProvider 为组件添加本地化支持属性。
