C#模拟MSN窗体抖动

窗体抖动是件很有意思的事情，就让我们看看一起来看看它的原理吧。 
其实是生成随机数，然后改变Form的左上角的坐标。
我用的是循环来弄得，其实可以用timer来控制.

 我把抖动分成了两种抖动:
1。 生成随机数，改变窗体左上角坐标，然后立即把窗体的坐上角坐标还原，继续循环。
2。 生成随机数，改变窗体左上角坐标，循环完毕之后，然后立即把窗体的坐上角坐标还原。

核心代码如下：

//第一种抖动
        private void button1_Click(object sender, EventArgs e)
        {
            int recordx = this.Left;            //保存原来窗体的左上角的x坐标
            int recordy = this.Top;             //保存原来窗体的左上角的y坐标

            Random random = new Random();      

            for (int i = 0; i < 100; i++)
            {
                int x = random.Next(rand);
                int y = random.Next(rand);
                if (x % 2 == 0)
                {
                    this.Left = this.Left + x;
                }
                else
                {
                    this.Left = this.Left - x;
                }
                if (y % 2 == 0)
                {
                    this.Top = this.Top + y;
                }
                else
                {
                    this.Top = this.Top - y;
                }

                this.Left = recordx;            //还原原始窗体的左上角的x坐标
                this.Top = recordy;             //还原原始窗体的左上角的y坐标
            }
           
        }

        //第二种抖动
        private void button2_Click(object sender, EventArgs e)
        {
            int recordx = this.Left;
            int recordy = this.Top;
            Random random = new Random();
            for (int i = 0; i < 50; i++)
            {
                int x = random.Next(rand);
                int y = random.Next(rand);
                if (x % 2 == 0)
                {
                    this.Left = this.Left + x;
                }
                else
                {
                    this.Left = this.Left - x;
                }
                if (y % 2 == 0)
                {
                    this.Top = this.Top + y;
                }
                else
                {
                    this.Top = this.Top - y;
                }
                System.Threading.Thread.Sleep(1);
            }
            this.Left = recordx;
            this.Top = recordy;
        }
