如何捕获方向键

在窗体中添加如下的重写方法来处理按键的信息:

/*键盘事件*/        protected override bool ProcessDialogKey(Keys keyData)        {            switch (keyData)            {                case Keys.Tab: MessageBox.Show(keyData.ToString());                    break;                case Keys.Left: MessageBox.Show(keyData.ToString());                    break;                case Keys.Right: MessageBox.Show(keyData.ToString());                    break;            }            if (keyData == Keys.Up || keyData == Keys.Down || keyData == Keys.Left || keyData == Keys.Right)                return false;            else                return base.ProcessDialogKey(keyData);        }
