代码如下：
void MainFormKeyDown(object sender, KeyEventArgs e)
{
int intDev = 10;
switch(e.KeyCode)
{
case Keys.Left:
Image1.Left -= intDev;
break;
case Keys.Right:
Image1.Left += intDev;
break;
case Keys.Up:
Image1.Top -= intDev;
break;
case Keys.Down:
Image1.Top += intDev;
break;
default:
break;
}
}
刚做了个简单的：
在Form窗体上添加一个PictureBox1控件
添加Form窗体的KeyDown消息响应函数
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
switch (e.KeyCode)
{
case Keys.Up:
pictureBox1.Top -=5;
break;
case Keys.Down:
pictureBox1.Top += 5;
break;
case Keys.Right:
pictureBox1.Left += 5;
break;
case Keys.Left:
pictureBox1.Left -= 5;
break;
default:
break;
}
}
}
}
使用keyDown事件，
if(e.keycode==keys.Left)
{
//如果按下左键，图片的坐标就左移5个像素
pictureBox.Location=new point (pictureBox.Location.X-5,pictureBox.Location.Y);
}
窗体的坐标原点是在窗体的最左上角，往右X轴加，往下Y轴加
首先要实现Form的onKeyDown的事件。
然后在里面这样写:
int dx=10;//以10像素为单位偏移
switch(KeyEvent.KeyCode)
{
case KeyCode.UP:
pictureBox1.Top-=dx;
break;
case KeyCode.Down:
pictureBox1.Top+=dx;
break;
case KeyCode.Left:
pictureBox1.Left-=dx;
break;
case KeyCode.Right:
pictureBox1.Left+=dx;
break;
}
//大致是这个思路。没调试，将就看吧
刚做了个简易的，截图发不了，被度娘吞了，有问题可以hi我
