当按下默认键时显示按钮按下效果

Question

当我按下我的默认键（输入）时，我希望我的按钮具有按下并释放的效果（模拟鼠标按下）。

我试图这样做

private void OnKeyDownHandler(object sender, KeyEventArgs e) 
     { 
      if (e.Key == Key.Enter) 
      { 
       VisualStateManager.GoToState(btnLogin, "Pressed", true); 
       System.Threading.Thread.Sleep(300); 
       VisualStateManager.GoToState(btnLogin, "Normal", true); 
       btnLogin_Click(sender, e); 

      } 
     } 

无法得到它的工作。
