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);
}
