在按钮点击事件中清除许多Inkcanvases中选择的Inkcanvas的笔划 [英] Clear the strokes of the seleted Inkcanvas among many Inkcanvases ,on button click event

问题描述

我在GUI上有10个墨迹。我想通过选择任何方法（最好是鼠标右键）来清除心室Inkcanvas的笔画。之后，当用户点击按钮时，应该删除墨迹中的笔画。在这个程序中，Inkcanvases是通过使用单独的类创建的，并使用stackpanel添加它们。可以告诉我选择墨迹的最佳方法。

  public   partial   class  MainWindow：Window 
 {
 
  public  InkCanvas [] mcanvas; 
 
 Class1 mycanvas1 =  new  Class1（  A）; 
 Class1 mycanvas2 =  new  Class1（  AA ）; 
 ............................... 
 Class1 mycanvas10 =  new  Class1（  AHA）; 
 
  public  MainWindow（）
 {
 InitializeComponent（）; 
 
 Stkm.Children.Add（mycanvas1）; 
 Stkm.Children.Add（mycanvas2）; 
 .............................. 
 Stkm.Children.Add（mycanvas10）; 
 
 mycanvas1.Name = mycanvas1.name; 
 mycanvas2.Name = mycanvas2.name; 
 ............................... 
 mycanvas10.Name = mycanvas10.name; 
 InkCanvas [] myCanvas = {mycanvas1，mycanvas2，mycanvas3，mycanvas4，mycanvas5，mycanvas6，mycanvas7，mycanvas8，mycanvas9，mycanvas10}; 
 mcanvas = myCanvas; 
 
} 
 
  public   void  Button_Click_1（< span class =code-keyword> object  sender，RoutedEventArgs e）
 {
 
 
} 
 
 
}
