enum Direction
{
Up,Right,Down,Left
}
public partial class Form1 : Form
{
Direction dir;
private void getDirection()
{
int x = button1.Location.X;
int y = button1.Location.Y;
switch (dir)
{
case Direction.Up:
button1.Location = new System.Drawing.Point(x, y - 10);
break;
case Direction.Down:
button1.Location = new System.Drawing.Point(x + 10, y);
break;
case Direction.Right:
button1.Location = new System.Drawing.Point(x, y + 10);
break;
case Direction.Left:
button1.Location = new System.Drawing.Point(x - 10, y);
break;
default:
break;
}
string s = e.KeyChar.ToString();
MessageBox.Show("按下的键为："+s+"","提示");
}
private void Form1_Load(object sender, EventArgs e)
{
private void getDirection();
}

//用按钮button1的KeyDown事件
private void btnHelp_KeyDown(object sender, KeyEventArgs e)
{
int x = button1.Location.X;
int y = button1.Location.Y;
switch (e.KeyCode)
{
case Keys.W:
