绑定到嵌套静态类中的属性 [英] Bind to property in a nested static class

问题描述

我的结构如下:

public static class Constants {
  public static class Foo {
    public static string Bar {
      get {
        //Constants.Foo.Bar == "FooBar"
        return "FooBar";
      }
    }
  }
}

我想将此绑定到用户控件中的按钮上.

I want to bind this to a button in a usercontrol.

<Button Content="{Binding Source={x:Static ns:Constants.Foo.Bar}}" />

(其中ns指向定义常量"的程序集和名称空间).
这导致两个错误:

(where ns points to the assembly and namespace where "Constants" is defined).
This results in two errors:

• 找不到类型'Constants.Foo'.请注意，类型名称区分大小写."
• 未找到类型'ns:Constants.Foo'."

• "Cannot find the type 'Constants.Foo'. Note that type names are case sensitive."
• "Type 'ns:Constants.Foo' was not found."

我也尝试过:

<Button Content="{Binding Source={x:Static ns:Constants+Foo.Bar}}" />

这会导致一个错误:

• 未找到类型'ns:Constants + Foo'."

• "Type 'ns:Constants+Foo' was not found."

是否可以绑定到静态类中的静态类中的静态属性?如果是，怎么办?

Is is possible to bind to a static property in a static class in a static class? If yes, how?

推荐答案

这对我有用

 <Button Content="{Binding Source={x:Static local:Constants+Foo.Bar}}" />

本地为

 xmlns:local="clr-namespace:WpfTestApp1"
