XmlnsDefinitionAttribute 类

定义

指定 XAML 命名空间与 CLR 命名空间之间按程序集进行的映射,然后 XAML 对象编写器或 XAML 架构上下文将其用于类型解析。Specifies a mapping on a per-assembly basis between a XAML namespace and a CLR namespace, which is then used for type resolution by a XAML object writer or XAML schema context.

属性

注解

将一个或多个 XmlnsDefinitionAttribute 特性应用于程序集,以便为 XAML 使用标识程序集内的类型。Apply one or more XmlnsDefinitionAttribute attributes to assemblies in order to identify the types within the assembly for XAML usage.

若要查找返回到 XAML 文件中的对象元素用法或对象引用的适当类型,XAML 处理器会搜索每个引用的程序集以查找 @no__t 的应用程序。To find the appropriate types that back object element usages or object references in a XAML file, a XAML processor searches each referenced assembly for XmlnsDefinitionAttribute applications. 通常,XAML 架构上下文会提供此信息。Generally the XAML schema context supplies this information.

在 XAML 文件中,如果对象元素或属性元素的 xmlns 特性与 XmlnsDefinitionAttribute 中的 @no__t 匹配,则 XAML 处理器将使用存储在 @no__t 中的 ClrNamespace 和 @no__t,以针对程序集中的类型进行类型解析。In a XAML file, if the xmlns attribute for an object element or property element matches the XmlNamespace in the XmlnsDefinitionAttribute, the XAML processor uses the ClrNamespace and AssemblyName stored in the XmlnsDefinitionAttribute for type resolution against types in the assembly.

在 .NET Framework 的以前版本中,此类存在于 WPF 特定的程序集 WindowsBase 中。In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. .NET Framework 4.NET Framework 4 中,XmlnsDefinitionAttribute 位于 system.exception 程序集中。In .NET Framework 4.NET Framework 4, XmlnsDefinitionAttribute is in the System.Xaml assembly. 有关详细信息,请参阅 Types Migrated from WPF to System.XamlFor more information, see Types Migrated from WPF to System.Xaml.
