private void button1_Click(object sender, System.Windows.RoutedEventArgs e) 
{ 
Application.Current.Shutdown(); 
} 

當我點擊按鈕，應用程序關閉。這就是我想要的。 但是當我點擊其中一個擴展器時，應用程序也會關閉。如何避免這種情況？當用戶點擊三個箭頭中的一個時，我不希望應用程序關閉。

嘗試檢查點擊來源（如點擊事件冒泡直到有人明確處理它們）。而且由於按鈕是擴展的父，它會過於接收其click事件（你的意思是把擴展外按鈕？）：

private void button1_Click(object sender, System.Windows.RoutedEventArgs e) 
{ 
    if (e.Source == this.button1) 
    { 
    Application.Current.Shutdown(); 
    } 
}
