c#窗体捕捉方向键

本文主要是介绍c#窗体捕捉方向键，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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();}

方法2

参考代码

private void Form1_KeyDown(object sender, KeyEventArgs e)
{if (e.KeyCode == Keys.Left)this.Left -= 100;if (e.KeyCode == Keys.Right)this.Left += 100;if (e.KeyCode == Keys.Up)this.Left -= 10;if (e.KeyCode == Keys.Down)this.Left += 10;}
