WPF ComboBox Binding Enum

什么都不说，先看代码

枚举：

namespace WpfAppTest
{
    public enum Week
    {
        Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
    }
}

页面：

<Window x:Class="WpfAppTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:local="clr-namespace:WpfAppTest"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.Resources>
            <ObjectDataProvider x:Key="NameWeek" MethodName="GetNames" ObjectType="{x:Type sys:Enum}">
                <ObjectDataProvider.MethodParameters>
                    <x:Type TypeName="local:Week"/>
                </ObjectDataProvider.MethodParameters>
            </ObjectDataProvider>
            <ObjectDataProvider x:Key="ValueWeek" MethodName="GetValues" ObjectType="{x:Type sys:Enum}">
                <ObjectDataProvider.MethodParameters>
                    <x:Type TypeName="local:Week"/>
                </ObjectDataProvider.MethodParameters>
            </ObjectDataProvider>
        </Grid.Resources>
        <ComboBox SelectedValue="{Binding SelectedWeek}" ItemsSource="{Binding Source={StaticResource NameWeek}}" HorizontalAlignment="Left" Height="50" Margin="38,40,0,0" VerticalAlignment="Top" Width="150"/>
        <ComboBox SelectedValue="{Binding SelectedWeek}" ItemsSource="{Binding Source={StaticResource ValueWeek}}" HorizontalAlignment="Left" Height="50" Margin="288,40,0,0" VerticalAlignment="Top" Width="150"/>
    </Grid>
</Window>

后台：

using System.Windows;

namespace WpfAppTest
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DataContext = this;
        }

        public Week SelectedWeek
        {
            get { return (Week)GetValue(SelectedWeekProperty); }
            set { SetValue(SelectedWeekProperty, value); }
        }
        public static readonly DependencyProperty SelectedWeekProperty =
            DependencyProperty.Register("SelectedWeek", typeof(Week), typeof(MainWindow), new PropertyMetadata(default(Week)));
    }
}

之前看网上的例子都是用GetNames反射的，但绑了SelectedValue却只能从界面到后台，后来看了Enum的代码才明白要用GetValues

System.Enum:

public static string[] GetNames(Type enumType);
public static Array GetValues(Type enumType);
