WPF 绑定枚举值

前台Xaml

  <ComboBox x:Name="cmboxStretch"  Width="" Height="" HorizontalAlignment="Left" Margin="5 0 0 0"
                             SelectedItem="{Binding Path=Stretch}"
                             VerticalContentAlignment="Center">
            </ComboBox>

  <Viewbox Stretch="{Binding SelectedValue,ElementName=cmboxStretch}" Grid.Row="" x:Name="viewBox">
  </Viewbox>

后台代码

 cmboxStretch.ItemsSource= System.Enum.GetValues(typeof(Stretch));

选择Combox就能看到ViewBox属性值Stretch在变化了。
