试着用

<ComboBox ItemsSource="{Binding Source={StaticResource ExampleEnumValues}}"
    SelectedValue="{Binding Path=ExampleProperty}" />

看到所有的东西，看到某些过于复杂的解决方案如何成为最琐碎问题的“标准(反)模式”是一件痛苦的事情:应该避免实现MarkupExtension的开销和复杂性，特别是使用属性修饰枚举值。简单地实现一个数据模型。

通常，向用户显示枚举值名称是一个坏主意。枚举不应该显示在UI中。它们是在编程上下文中使用的常量。值名称不用于显示。他们是为了称呼工程师，因此这些名字通常使用特殊的语义和词汇，就像科学词汇一样，不被公众所理解。不要犹豫，为显示的值创建一个专用的源。

当涉及到本地化时，问题变得更加明显。 这就是为什么所有贴出来的答案都是过度设计的。它们使一个非常简单的问题看起来像一个关键问题。 最平凡的解决方案就是最好的解决方案，这是事实。最初问题的主题绝对不是个例外。 我强烈建议不要使用任何提供的答案。尽管它们可能会起作用，但它们会给一个微不足道的问题增加不必要的复杂性。

请注意，您总是可以通过调用静态enum将枚举转换为其值或值名的列表。GetValues或Enum。GetNames，它们都返回一个IEnumerable，你可以直接分配给组合框。ItemsSource属性，例如通过数据绑定。

IEnumerable<ExampleEnum> values = Enum.GetValues<ExampleEnum>();
IEnumerable<string> names = Enum.GetNames<ExampleEnum>();

Usually, when defining an enumeration, you don't have UI in mind. Enumeration value names are not chosen based on UI design rules. Usually, UI labels and text in general are created by people with no developer or programmer background. They usually provide all the required translations to localize the application. There are many good reasons not to mix UI with the application. You would never design a class and name its properties with UI (e.g., DataGrid columns) in mind. You may want your column header to contain whitespaces etc. Same reason why exception messages are directed at developers and not users. You definitely don't want to decorate every property, every exception, enum or whatever data type or member with attributes in order to provide a display name that makes sense to the user in a particular UI context. You don't want to have UI design bleed into your code base and polute your classes. Application and its user interface - this are two different problems. Adding this abstract or virtual extra layer of separation allows e.g., to add enum values that should not be displayed. Or more general, modify code without having to break or modify the UI.

您应该使用一个简单的IValueConverter或一个专门的类来提供这些显示值作为绑定源，而不是使用属性和实现额外的逻辑负载来提取它们的值(使用反射)。 坚持最常见的模式，并为ComboBox项目实现一个数据模型，其中类具有枚举类型的属性作为成员，这有助于您识别ComboBox。SelectedItem(如果你需要枚举值):

ExampleEnum.cs

// Define enumeration without minding any UI elements and context
public enum ExampleEnum 
{ 
    FooBar = 0, 
    BarFoo 
}

ExampleClass.cs

// Define readable enum display values in the UI context.
// Display names can come from a localizable resource.
public class BindingSource : INotifyPropertyChanged
{
    public BindingSource()
    {
        ItemModels = new List<ItemModel> 
        {
            new ItemModel { Label = "Foo Bar Display", Value = ExampleEnum.FooBar },
            new ItemModel { Label = "Bar Foo Display", Value = ExampleEnum.BarFoo }
        }
    }

    public List<ItemModel> ItemModels { get; }

    private ItemModel selectedItemModel;
    public ItemModel SelectedItemModel { get => selectedItemModel; => set and notify; }
}

ItemModel.cs

public class ItemModel
{   
    public string Label { get; set; }
    public ExampleEnum Value { get; set; }
}

MainWindow.xaml

<Window>
  <Window.DataContext>
    <BindingSource />
  </Window.DataContext>

  <ComboBox ItemsSource="{Binding ItemModels}"
            DisplayMemberName="DisplayValue"
            SelectedItem="{Binding SelectedItemModel}" />
</Window>

使用ObjectDataProvider:

<ObjectDataProvider x:Key="enumValues"
   MethodName="GetValues" ObjectType="{x:Type System:Enum}">
      <ObjectDataProvider.MethodParameters>
           <x:Type TypeName="local:ExampleEnum"/>
      </ObjectDataProvider.MethodParameters>
 </ObjectDataProvider>

然后绑定到静态资源:

ItemsSource="{Binding Source={StaticResource enumValues}}"

您可以创建自定义标记扩展。

用法示例:

enum Status
{
    [Description("Available.")]
    Available,
    [Description("Not here right now.")]
    Away,
    [Description("I don't have time right now.")]
    Busy
}

在你的XAML顶部:

    xmlns:my="clr-namespace:namespace_to_enumeration_extension_class

然后……

<ComboBox 
    ItemsSource="{Binding Source={my:Enumeration {x:Type my:Status}}}" 
    DisplayMemberPath="Description" 
    SelectedValue="{Binding CurrentStatus}"  
    SelectedValuePath="Value"  /> 

而实施……

public class EnumerationExtension : MarkupExtension
  {
    private Type _enumType;


    public EnumerationExtension(Type enumType)
    {
      if (enumType == null)
        throw new ArgumentNullException("enumType");

      EnumType = enumType;
    }

    public Type EnumType
    {
      get { return _enumType; }
      private set
      {
        if (_enumType == value)
          return;

        var enumType = Nullable.GetUnderlyingType(value) ?? value;

        if (enumType.IsEnum == false)
          throw new ArgumentException("Type must be an Enum.");

        _enumType = value;
      }
    }

    public override object ProvideValue(IServiceProvider serviceProvider) // or IXamlServiceProvider for UWP and WinUI
    {
      var enumValues = Enum.GetValues(EnumType);

      return (
        from object enumValue in enumValues
        select new EnumerationMember{
          Value = enumValue,
          Description = GetDescription(enumValue)
        }).ToArray();
    }

    private string GetDescription(object enumValue)
    {
      var descriptionAttribute = EnumType
        .GetField(enumValue.ToString())
        .GetCustomAttributes(typeof (DescriptionAttribute), false)
        .FirstOrDefault() as DescriptionAttribute;


      return descriptionAttribute != null
        ? descriptionAttribute.Description
        : enumValue.ToString();
    }

    public class EnumerationMember
    {
      public string Description { get; set; }
      public object Value { get; set; }
    }
  }

你可以这样考虑:

define a style for textblock, or any other control you want to use to display your enum: <Style x:Key="enumStyle" TargetType="{x:Type TextBlock}"> <Setter Property="Text" Value="&lt;NULL&gt;"/> <Style.Triggers> <Trigger Property="Tag"> <Trigger.Value> <proj:YourEnum>Value1<proj:YourEnum> </Trigger.Value> <Setter Property="Text" Value="{DynamicResource yourFriendlyValue1}"/> </Trigger> <!-- add more triggers here to reflect your enum --> </Style.Triggers> </Style> define your style for ComboBoxItem <Style TargetType="{x:Type ComboBoxItem}"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <TextBlock Tag="{Binding}" Style="{StaticResource enumStyle}"/> </DataTemplate> </Setter.Value> </Setter> </Style> add a combobox and load it with your enum values: <ComboBox SelectedValue="{Binding Path=your property goes here}" SelectedValuePath="Content"> <ComboBox.Items> <ComboBoxItem> <proj:YourEnum>Value1</proj:YourEnum> </ComboBoxItem> </ComboBox.Items> </ComboBox>

如果枚举很大，当然可以在代码中执行相同的操作，从而节省大量输入。 我喜欢这种方法，因为它使本地化变得容易——你定义一次所有的模板，然后，你只更新你的字符串资源文件。

试着用

<ComboBox ItemsSource="{Binding Source={StaticResource ExampleEnumValues}}"
    SelectedValue="{Binding Path=ExampleProperty}" />
