無法將類型'MouseEventHandler'隱式轉換爲'RoutedEventHandler

Question

我試圖繼承方法button1_click，並且我得到了上面的消息，如何解決該問題？

namespace visualinheritance 
{ 
    public partial class usercontrolcommon : UserControl 
    { 
     public usercontrolcommon() 
     { 
      InitializeComponent(); 
     } 

     public void button1_Click(object sender, RoutedEventArgs e) 
     { 
      MessageBox.Show("usercontrolcommon"); 
     } 
    } 
} 

namespace visualinheritance 
{ 
    public partial class usercontrol1 : usercontrolcommon 
    { 
     public usercontrol1() 
     { 
      InitializeComponent(); 
      this.button1.Click += new MouseEventHandler(button1_Click); 

     } 

    } 
}

按鈕點擊事件不是鼠標事件。只需將處理程序更改爲button1.Click += button1_Click;即可運行
