本文介绍了如何在C#中实现窗体抖动，包括通过线程和Timer两种方式，并详细讲解了随机验证码的生成，包括三种不同的方法，涉及颜色和字体大小的随机变化。文章末尾邀请读者对不足之处提出指正。

用线程实现窗口抖动

下面是代码过程

  private void Form2_Load(object sender, EventArgs e)
        {
   
   
            this.CenterToScreen();
        }

        private void douyidou_Click(object sender, EventArgs e)
        {
   
   
            for (int i = 0; i < 20; i++)
            {
   
   
                this.Location = new Point(this.Left + 10,this.Top );
                Thread.Sleep(10);
                this.Location = new Point(this.Left, this.Top + 10);
                Thread.Sleep(10);
                this.Location = new Point(this.Left - 10, this.Top);
                Thread.Sleep(10);
                this.Location = new Point(this.Left - 10, this.Top);
                Thread.Sleep(10);
                this.Location = new Point(this.Left, this.Top - 10);
                Thread.Sleep(10);
                this.Location = new Point(this.Left, this.Top - 10);
                Thread.Sleep(10);
                this.Location = new Point(this.Left + 10, this.Top);
                Thread.Sleep(10);
                this.Location = new Point(this.Left + 10, this.Top);
                Thread.Sleep(10);
                this.Location = new Point(this.Left, this.Top + 10);
                Thread.Sleep(10);
                this.Location = new Point(this.Left - 10, this.Top);
                Thread.Sleep(10);

            }
        }
    }
}

随机验证码

1）第一种方法：

  private void yanzhengma_Click(object sender, EventArgs e)
        {
   
   
            string ai = "";
            Random p = new Random();
            for (int i = 0; i < 4; i++)
            {
   
   
                int type = p.Next(0,
