无法在WPF中找到静态引用的枚举类型 [英] Unable to find enum type for static reference in WPF

问题描述

我试图将一个枚举绑定到WPF中的单选按钮（灵感来自这个答案），但是我找不到转换器参数的枚举类型：

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:

枚举在以下方式

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

        public MySelections CurrentSelection;

        ...

    }
}

$ b $我试图绑定这样的复选框（数据上下文被认为是正确的，并实现了价值转换器）。

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：Static型号：Enums.MySelections.one} 不断抛出错误，类型型号：Enums.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.

如何找到我的枚举类型？

How can I find my enum type?

推荐答案

您可以将其声明为你的课程：

You could declare it outside of your class:

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

    public  class Enums
    {
        public MySelections CurrentSelection;

然后这个xaml将工作：

And then this xaml will work:

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

---

x：static 标记具有固定的语法：

---

The x:Static markup has the fixed syntax:

{x：静态
前缀：typeName.staticMemberName}

{x:Static prefix:typeName.staticMemberName}
