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

你可以通过在Window Loaded事件处理程序中放置以下代码来做到这一点，例如:

yourComboBox.ItemsSource = Enum.GetValues(typeof(EffectStyle)).Cast<EffectStyle>();

如果你需要在XAML中绑定它，你需要使用ObjectDataProvider创建可用的对象作为绑定源:

<Window x:Class="YourNamespace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:System="clr-namespace:System;assembly=mscorlib"
        xmlns:StyleAlias="clr-namespace:Motion.VideoEffects">
    <Window.Resources>
        <ObjectDataProvider x:Key="dataFromEnum" MethodName="GetValues"
                            ObjectType="{x:Type System:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="StyleAlias:EffectStyle"/>
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
    </Window.Resources>
    <Grid>
        <ComboBox ItemsSource="{Binding Source={StaticResource dataFromEnum}}"
                  SelectedItem="{Binding Path=CurrentEffectStyle}" />
    </Grid>
</Window>

请注意下面的代码:

xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:StyleAlias="clr-namespace:Motion.VideoEffects"

指导如何映射可以在MSDN上读取的命名空间和程序集。

<Window.Resources>
        <ObjectDataProvider x:Key="DiaryTypeEnum"
       MethodName="GetValues" ObjectType="{x:Type System:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="z:Enums+DiaryType"/>
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
</Window.Resources>
...
<ComboBox ItemsSource="{Binding Source={StaticResource DiaryTypeEnum}}" SelectedItem="{x:Static z:Enums+DiaryType.Defect}" />

其中z它的xmlns:z="clr-namespace:ProjName。助手”

我的Enum变成静态类

  public static class Enums
    {
        public enum DiaryType
        {
            State,
            Defect,
            Service,
            Other
        }
        public enum OtherEnumOrMethods
        {
           //TODO
        }
    }

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。

public class EnumItemsConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (!value.GetType().IsEnum)
            return false;

        var enumName = value.GetType();
        var obj = Enum.Parse(enumName, value.ToString());

        return System.Convert.ToInt32(obj);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return Enum.ToObject(targetType, System.Convert.ToInt32(value));
    }
}

如果您直接绑定到枚举对象模型属性，您应该使用这种Enum值转换器扩展Rogers和Greg的回答。

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
