UidPropertyAttribute 类


指示提供 X:uid 指令值的类的 CLR 属性。Indicates the CLR property of a class that provides the x:Uid Directive value.

public ref class UidPropertyAttribute sealed : Attribute
public sealed class UidPropertyAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=false)]
public sealed class UidPropertyAttribute : Attribute
type UidPropertyAttribute = class
    inherit Attribute
Public NotInheritable Class UidPropertyAttribute
Inherits Attribute


UidPropertyAttribute 是 XAML 语言特性,用于标识标记中的元素节点,以便能够对其进行唯一标识。The UidPropertyAttribute is a XAML language attribute that identifies element nodes in markup so that they can be uniquely identified. 尽管 x:Uid 的模型可能更常见,但 XAML 元素的唯一标识符的一种用法是用于本地化工具,因此,需要本地化的 XAML 语言组件可以生成伴随本地化源,并与原始 XAML 重新集成。Although the model for x:Uid is potentially more general, one usage of unique identifiers for XAML elements is for localization tools, so that XAML language components that need localization can generate a companion localization source and then re-integrated with the original XAML. 有关如何在 WPF 本地化中使用 x:Uid 的详细信息。For more information on how x:Uid is used in WPF localization. 请参阅WPF 全球化和本地化概述see WPF Globalization and Localization Overview.

在 .NET Framework 4 之前的 .NET Framework 版本中,此类存在于 WPF 特定的程序集 WindowsBase 中。In versions of the .NET Framework before .NET Framework 4, this class existed in the WPF-specific assembly WindowsBase. 在 .NET Framework 4 及更高版本中,UidPropertyAttribute 在 system.exception 程序集中。In .NET Framework 4 and later versions, UidPropertyAttribute 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.
