突然想起来flash有碰撞反弹飘动as控制的效果，所以想起来用c#也来做一个桌面飘动碰撞反弹无标题栏窗体。有点像中了恶意病毒广告效果。
主要代码如下（使用了一timer控件和一Button(为了我自己控制)，窗体的BorderStyle设置为None）：
复制代码 代码如下:
int ScreenWidth = SystemInformation.PrimaryMonitorMaximizedWindowSize.Width;
int ScreenHeight = SystemInformation.PrimaryMonitorMaximizedWindowSize.Height;
private int speedX = 4;
private int speedY = 3;
private bool canMove = true;
int myswitch = 1;//为了我可以控制停止所以添加的飘与停的切换开关
private void timer1_Tick(object sender, EventArgs e)
{
if (canMove)
{
this.DesktopLocation = new Point(this.DesktopLocation.X + speedX, this.DesktopLocation.Y + speedY);
if (this.DesktopLocation.X + this.Width >= ScreenWidth || this.DesktopLocation.X < 0)
{
speedX = -speedX;
}
if (this.DesktopLocation.Y + this.Height >= ScreenHeight || this.DesktopLocation.Y < 0)
{
speedY = -speedY;
}
}
}
private void button1_Click(object sender, EventArgs e)
{
myswitch *= -1;
if (myswitch == -1)
{
canMove = false;
//button1.Text = "飘动";
}
else
{
canMove = true;
//button1.Text = "停止";
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void Form1_DoubleClick(object sender, EventArgs e)
{
Application.Exit();
}
暂写这么多，有时间把它再增强下更像恶意广告。~
