我喜欢汤姆。maruska的答案，但我需要支持我的模板在运行时可能遇到的任何枚举类型。为此，我必须使用绑定来指定标记扩展的类型。我从尼古拉的回答中得到了答案。anykienko提出了一个非常灵活的标记扩展，它可以在我能想到的任何情况下工作。它是这样消耗的:

<ComboBox SelectedValue="{Binding MyEnumProperty}" 
          SelectedValuePath="Value"
          ItemsSource="{local:EnumToObjectArray SourceEnum={Binding MyEnumProperty}}" 
          DisplayMemberPath="DisplayName" />

上面引用的混合标记扩展的源代码:

class EnumToObjectArray : MarkupExtension
{
    public BindingBase SourceEnum { get; set; }

    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        IProvideValueTarget target = serviceProvider.GetService(typeof(IProvideValueTarget)) as IProvideValueTarget;
        DependencyObject targetObject;
        DependencyProperty targetProperty;

        if (target != null && target.TargetObject is DependencyObject && target.TargetProperty is DependencyProperty)
        {
            targetObject = (DependencyObject)target.TargetObject;
            targetProperty = (DependencyProperty)target.TargetProperty;
        }
        else
        {
            return this;
        }

        BindingOperations.SetBinding(targetObject, EnumToObjectArray.SourceEnumBindingSinkProperty, SourceEnum);

        var type = targetObject.GetValue(SourceEnumBindingSinkProperty).GetType();

        if (type.BaseType != typeof(System.Enum)) return this;

        return Enum.GetValues(type)
            .Cast<Enum>()
            .Select(e => new { Value=e, Name = e.ToString(), DisplayName = Description(e) });
    }

    private static DependencyProperty SourceEnumBindingSinkProperty = DependencyProperty.RegisterAttached("SourceEnumBindingSink", typeof(Enum)
                       , typeof(EnumToObjectArray), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.Inherits));

    /// <summary>
    /// Extension method which returns the string specified in the Description attribute, if any.  Oherwise, name is returned.
    /// </summary>
    /// <param name="value">The enum value.</param>
    /// <returns></returns>
    public static string Description(Enum value)
    {
        var attrs = value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), false);
        if (attrs.Any())
            return (attrs.First() as DescriptionAttribute).Description;

        //Fallback
        return value.ToString().Replace("_", " ");
    }
}

上面所有的帖子都忽略了一个简单的技巧。可以从SelectedValue的绑定中找到如何自动地填充ItemsSource，以便您的XAML标记是正确的。

<Controls:EnumComboBox SelectedValue="{Binding Fool}"/>

例如，在ViewModel中

public enum FoolEnum
    {
        AAA, BBB, CCC, DDD

    };


    FoolEnum _Fool;
    public FoolEnum Fool
    {
        get { return _Fool; }
        set { ValidateRaiseAndSetIfChanged(ref _Fool, value); }
    }

ValidateRaiseAndSetIfChanged是我的INPC钩子。你的可能不同。

EnumComboBox的实现如下所示，但首先我需要一个小助手来获取我的枚举字符串和值

    public static List<Tuple<object, string, int>> EnumToList(Type t)
    {
        return Enum
            .GetValues(t)
            .Cast<object>()
            .Select(x=>Tuple.Create(x, x.ToString(), (int)x))
            .ToList();
    }

和主类(注意，我使用ReactiveUI通过WhenAny钩子属性更改)

using ReactiveUI;
using ReactiveUI.Utils;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reactive.Linq;
using System.Windows;
using System.Windows.Documents;

namespace My.Controls
{
    public class EnumComboBox : System.Windows.Controls.ComboBox
    {
        static EnumComboBox()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(EnumComboBox), new FrameworkPropertyMetadata(typeof(EnumComboBox)));
        }

        protected override void OnInitialized( EventArgs e )
        {
            base.OnInitialized(e);

            this.WhenAnyValue(p => p.SelectedValue)
                .Where(p => p != null)
                .Select(o => o.GetType())
                .Where(t => t.IsEnum)
                .DistinctUntilChanged()
                .ObserveOn(RxApp.MainThreadScheduler)
                .Subscribe(FillItems);
        }

        private void FillItems(Type enumType)
        {
            List<KeyValuePair<object, string>> values = new List<KeyValuePair<object,string>>();

            foreach (var idx in EnumUtils.EnumToList(enumType))
            {
                values.Add(new KeyValuePair<object, string>(idx.Item1, idx.Item2));
            }

            this.ItemsSource = values.Select(o=>o.Key.ToString()).ToList();

            UpdateLayout();
            this.ItemsSource = values;
            this.DisplayMemberPath = "Value";
            this.SelectedValuePath = "Key";

        }
    }
}

您还需要在Generic中正确设置样式。XAML或者你的盒子不会渲染任何东西，你会抓狂的。

<Style TargetType="{x:Type local:EnumComboBox}" BasedOn="{StaticResource {x:Type ComboBox}}">
</Style>

就是这样。这显然可以扩展到支持i18n，但会使帖子更长。

这个问题有很多很好的答案，我谦卑地提出我的答案。我发现我的比较简单，也比较优雅。它只需要一个值转换器。

给定一个枚举…

public enum ImageFormat
{
    [Description("Windows Bitmap")]
    BMP,
    [Description("Graphics Interchange Format")]
    GIF,
    [Description("Joint Photographic Experts Group Format")]
    JPG,
    [Description("Portable Network Graphics Format")]
    PNG,
    [Description("Tagged Image Format")]
    TIFF,
    [Description("Windows Media Photo Format")]
    WDP
}

还有价值转换器……

public class ImageFormatValueConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value is ImageFormat format)
        {
            return GetString(format);
        }

        return null;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value is string s)
        {
            return Enum.Parse(typeof(ImageFormat), s.Substring(0, s.IndexOf(':')));
        }
        return null;
    }

    public string[] Strings => GetStrings();

    public static string GetString(ImageFormat format)
    {
        return format.ToString() + ": " + GetDescription(format);
    }

    public static string GetDescription(ImageFormat format)
    {
        return format.GetType().GetMember(format.ToString())[0].GetCustomAttribute<DescriptionAttribute>().Description;

    }
    public static string[] GetStrings()
    {
        List<string> list = new List<string>();
        foreach (ImageFormat format in Enum.GetValues(typeof(ImageFormat)))
        {
            list.Add(GetString(format));
        }

        return list.ToArray();
    }
}

资源……

    <local:ImageFormatValueConverter x:Key="ImageFormatValueConverter"/>

XAML份...

    <ComboBox Grid.Row="9" ItemsSource="{Binding Source={StaticResource ImageFormatValueConverter}, Path=Strings}"
              SelectedItem="{Binding Format, Converter={StaticResource ImageFormatValueConverter}}"/>

视图模型……

    private ImageFormat _imageFormat = ImageFormat.JPG;
    public ImageFormat Format
    {
        get => _imageFormat;
        set
        {
            if (_imageFormat != value)
            {
                _imageFormat = value;
                OnPropertyChanged();
            }
        }
    }

产生的组合框……

我不建议这样做，但希望这能启发一个好的解决方案。

假设枚举是Foo。然后你可以这样做。

public class FooViewModel : ViewModel
{
    private int _fooValue;

    public int FooValue
    {
        get => _fooValue;
        set
        {
            _fooValue = value;
            OnPropertyChange();
            OnPropertyChange(nameof(Foo));
            OnPropertyChange(nameof(FooName));
        }
    }
    public Foo Foo 
    { 
        get => (Foo)FooValue; 
        set 
        { 
            _fooValue = (int)value;
            OnPropertyChange();
            OnPropertyChange(nameof(FooValue));
            OnPropertyChange(nameof(FooName));
        } 
    }
    public string FooName { get => Enum.GetName(typeof(Foo), Foo); }

    public FooViewModel(Foo foo)
    {
        Foo = foo;
    }
}

然后打开Window。Load方法，你可以将所有枚举加载到ObservableCollection<FooViewModel>中，你可以将它设置为组合框的DataContext。

我添加了我的评论(遗憾的是在VB中，但是这个概念可以很容易地复制到c#中)，因为我只是引用了这一点，并且不喜欢任何答案，因为它们太复杂了。没必要这么困难。

所以我想到了一个更简单的方法。将枚举数绑定到字典。将该字典绑定到组合框。

我的下拉列表框:

<ComboBox x:Name="cmbRole" VerticalAlignment="Stretch" IsEditable="False" Padding="2" 
    Margin="0" FontSize="11" HorizontalAlignment="Stretch" TabIndex="104" 
    SelectedValuePath="Key" DisplayMemberPath="Value" />

我的后台代码。希望这能帮助到其他人。

Dim tDict As New Dictionary(Of Integer, String)
Dim types = [Enum].GetValues(GetType(Helper.Enumerators.AllowedType))
For Each x As Helper.Enumerators.AllowedType In types
    Dim z = x.ToString()
    Dim y = CInt(x)
    tDict.Add(y, z)
Next

cmbRole.ClearValue(ItemsControl.ItemsSourceProperty)
cmbRole.ItemsSource = tDict

我使用MarkupExtension的另一种解决方案。

I made class which provides items source: public class EnumToItemsSource : MarkupExtension { private readonly Type _type; public EnumToItemsSource(Type type) { _type = type; } public override object ProvideValue(IServiceProvider serviceProvider) { return Enum.GetValues(_type) .Cast<object>() .Select(e => new { Value = (int)e, DisplayName = e.ToString() }); } } That's almost all... Now use it in XAML: <ComboBox DisplayMemberPath="DisplayName" ItemsSource="{persons:EnumToItemsSource {x:Type enums:States}}" SelectedValue="{Binding Path=WhereEverYouWant}" SelectedValuePath="Value" /> Change 'enums:States' to your enum
