找不到枚举类型在WPF静态引用 [英] Unable to find enum type for static reference in WPF

问题描述

我试图枚举绑定到WPF中的单选按钮（通过<一个启发href="http://stackoverflow.com/questions/397556/wpf-how-to-bind-radiobuttons-to-an-enum/2908885#2908885">this回答），但我很难找到的枚举类型转换器参数：

I'm trying to bind an enum to a radio button in WPF (Inspired by this answer), but I have trouble finding the enum type for the converter parameter:

枚举以下面的方式定义

namespace Application.Models
{
    public class Enums
    {
        public enum MySelections { one, two ,three };

        public MySelections CurrentSelection;

        ...

    }
}

我想现在要绑定的复选框，这样的（数据上下文被认为是正确的，值转换器实现的：）

I am trying to bind now the checkbox like this (The data context is assumed to be correct and the value converter implemented:)

<Window x:Class="Application.MainWindow"
        ....
        xnlns:models="clr-namespace:Application.Models" >

...
<RadioButton Content="One"
             IsChecked="{Binding Path=CurrentSelection, Converter={StaticResource EnumToBooleanConverter}, ConverterParameter={x:Static models:Enums.MySelections.one}}" />
...

问题在于 {X：静态模式：Enums.MySelections.one} 它不断地引发错误的类型型号：枚举。 MySelections 找不到。

The problem lies with {x:Static models:Enums.MySelections.one} which constantly throws the error that the type models:Enums.MySelections could not be found.

我如何才能找到我的枚举类型？

How can I find my enum type?

推荐答案

您可以将您的类之外声明它：

You could declare it outside of your class:

namespace Application.Models
{
    public enum MySelections { one, two, three };

    public  class Enums
    {
        public MySelections CurrentSelection;

和那么这XAML将工作：

And then this xaml will work:

.... ConverterParameter={x:Static models:MySelections.one}

---

借助 X：静态 标记有固定的语法：

---

The x:Static markup has the fixed syntax:

{X：静态   preFIX：typeName.staticMemberName}

{x:Static prefix:typeName.staticMemberName}
