WPF TextBlock 雙擊命令

TextBlock使用EventTrigger觸發命令，只能使用MouseLeftButtonDown或者MouseLeftButtonUp觸發，要實現鼠標雙擊觸發命令，可以使用InputBinding,具體代碼如下

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