C# WPF层事件分离

我有一个最高的层叫做“画布”，用于显示图片。然后，我尝试使用event menuCanvas_触地到名为“menuCanvas”的最低层，该层显示我的工作区菜单。但是，当我触摸图片时，它会转到menuCanvas_触地。它应该位于menuCanvas层

<Canvas x:Name="menuCanvas"  
     TouchDown="menuCanvas_TouchDown" TouchUp="menuCanvas_TouchUp" 
    TouchMove="menuCanvas_TouchMove" TouchLeave="menuCanvas_TouchLeave" 
    TouchEnter="menuCanvas_TouchEnter"                 
    VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  
    Background="Transparent"
    IsManipulationEnabled="True">


    <Canvas x:Name="drawCanvas"  
     TouchDown="drawCanvas_TouchDown" TouchUp="drawCanvas_TouchUp" 
    TouchMove="drawCanvas_TouchMove" TouchLeave="drawCanvas_TouchLeave" 
    TouchEnter="drawCanvas_TouchEnter"                 
    VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  
    Background="Transparent"
    IsManipulationEnabled="True">
            <Canvas x:Name="canvas"></Canvas>
            </Canvas>
    </Canvas>

你试过使用e.OriginalSource吗？您可以检查事件的来源

if(e.OriginalSource == menuCanvas)
{
    //Your code
}

你能发布

drawCanvas\u触地

，

drawCanvas\u触地

等的代码吗。

if(e.OriginalSource == menuCanvas)
{
    //Your code
}
