如何使用

定向键盘移动该面板？
我将在控件上注册KeyUp事件，并按如下方式处理：

    private void lblMove_KeyUp(object server, KeyEventArgs e)
    {
          Point location = button1.Location;
          switch(e.KeyCode)
          {
            case Keys.Up: 
                location.Y = location.Y -1;
                break;
            case Keys.Down:
                location.Y = location.Y + 1;
                break;
            case Keys.Right:
                location.X = location.X + 1;
                break;
            case Keys.Left:
                location.X = location.X - 1;
                break;
          }

          button1.Location = location;
    }

尝试使用OnKeyDown事件
    private void lblMove_KeyUp(object server, KeyEventArgs e)
    {
          Point location = button1.Location;
          switch(e.KeyCode)
          {
            case Keys.Up: 
                location.Y = location.Y -1;
                break;
            case Keys.Down:
                location.Y = location.Y + 1;
                break;
            case Keys.Right:
                location.X = location.X + 1;
                break;
            case Keys.Left:
                location.X = location.X - 1;
                break;
          }

          button1.Location = location;
    }
