WPF TextBlock 双击命令

TextBlock使用EventTrigger触发命令，只能使用MouseLeftButtonDown或者MouseLeftButtonUp触发，要实现鼠标双击触发命令，可以使用InputBinding,具体代码如下

<TextBlock>
    <TextBlock.InputBinding>
            <MouseBinding MouseAction="LeftDoubleClick" 
                                  Command="{Binding DoubleClickCommand}"
                                  CommandParameter="{Binding }"/>
     </TextBlock.InputBinding>
</TextBlock>
