C # simulate MSN form jitter

The form jitter is a very interesting thing, let's look at how it works together.

is actually generating random numbers, and then changing the coordinates of the top left corner of the form.

I use a loop to make it, but I can use a timer to control it.

I split the jitter into two kinds of jitter:

1. Generate random numbers, change the upper-left corner of the form coordinates, and then immediately put the form's upper corner coordinates to restore, continue to cycle.

2. Generate random numbers, change the upper-left corner of the form coordinates, after the loop is complete, and then immediately put the form on the upper corner coordinates to restore.

The core code is as follows:

The first kind of jitter

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
      }
    }

The second kind of jitter

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;
    }
