短视频开发，实现窗体抖动

public class Shake
{
    /// <summary>
    /// 震动方法
    /// </summary>
    /// <param name="form">窗体</param>
    public void Vibration(Form form)
    {
        Point pOld = form.Location;//原来的位置
        int radius = 3;//半径
        for (int n = 0; n < 3; n++) //旋转圈数
        {
            //右半圆逆时针
            for (int i = -radius; i <= radius; i++)
            {
                 int x = Convert.ToInt32(Math.Sqrt(radius * radius - i * i));
                 int y = -i;
                 form.Location = new Point(pOld.X + x, pOld.Y + y);
                    Thread.Sleep(10);
            }
            //左半圆逆时针
            for (int j = radius; j >= -radius; j--)
            {
                 int x = -Convert.ToInt32(Math.Sqrt(radius * radius - j * j));
                 int y = -j;
                 form.Location = new Point(pOld.X + x, pOld.Y + y);
                 Thread.Sleep(10);
            }
        }
        //抖动完成，恢复原来位置
        form.Location = pOld;
    }
}
