绑定到ComboBox时如何在xaml中排除某些枚举成员? [英] How to exclude some enum members in the xaml when bound to a ComboBox?

问题描述

我正在使用VS 2010，.Net 4.0和C#.在将枚举绑定到ComboBox控件时，我希望能够排除枚举的某些成员.我似乎记得在一段时间的帖子中看到过针对这种功能的解决方案 回来，但我找不到了.

I am using VS 2010, .Net 4.0 and C#.  I want to be able to exclude certain members of an enumeration when binding the enumeration to a ComboBox control.  I seem to remember seeing a solution to this type of feature in a posting awhile back, but I can no longer find it.

我有一个这样的枚举:

public enum MyEnum
{
   First,
   Second,
   Third,
   Fourth,
   Fifth
}

我想像这样将枚举绑定到ComboBox上:

I want to bind the enum to a ComboBox like this:

<ObjectDataProvider MethodName="GetValues" ObjectType="{x:Type sys:Enum}" x:Key="MyEnumSelection">
   <ObjectDataProvider.MethodParameters>
      <x:Type TypeName="common:MyEnum"/>
   </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>

<ComboBox IsSynchronizedWithCurrentItem="True"
SelectedValue="{Binding Path=MyEnumProperty}" 
ItemsSource="{Binding Source={StaticResource MyEnumSelection}}"/>

我似乎还记得，可以通过在ItemsSource绑定代码中添加一些xaml语法来从枚举中排除某些成员.我认为它看起来像这样:

I seem to remember it was possible to exclude certain members from the enum by adding some xaml syntax in the ItemsSource binding code.  I think it looked something like this:

<ComboBox IsSynchronizedWithCurrentItem="True"
SelectedValue="{Binding Path=MyEnumProperty}" 
ItemsSource="{Binding Source={StaticResource MyEnumSelection}, Exclude="Fifth"}"/>

有人知道这样做的正确语法吗?可以排除的内容是否有限制?

Does anybody know the correct syntax to do this? Are there limitations to what can be excluded?
