方法1
实现方法参考代码：
private void Form1_Load(object sender, EventArgs e)
{
this.KeyPreview = true;
}
protected override bool ProcessDialogKey(Keys keyData)
{
if (keyData == Keys.Left || keyData == Keys.Right || keyData == Keys.Up || keyData == Keys.Down)
{
switch (keyData)
{
case Keys.Left:
KeyLeftPress();
break;
case Keys.Right:
KeyRightPress();
break;
case Keys.Up:
KeyUpPress();
break;
case Keys.Down:
KeyDownPress();
break;
}
}
return base.ProcessDialogKey(keyData);
}
public void KeyLeftPress()
{
}
public void KeyRightPress()
{
}
private void KeyUpPress()
{
}
private void KeyDownPress()
{
}
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
this.Text = e.KeyChar.ToString();
}
