C#——学习记录——实现一个摇奖机

创建一个窗体，写一个程序加深对线程的理解，添加相应控件

写入如下代码

   private void button1_Click(object sender, EventArgs e)
        {
            if(flag==false)
            {
                flag = true;
                this.button1.Text = "暂停";
                Thread th = new Thread(PlayGame);
                th.IsBackground = true;
                th.Start();
            }
            else
            {
                flag = false;
            }

        }
        public void PlayGame()
        {
            Random r = new Random();
            while(flag)
            {
                this.label1.Text = r.Next(0, 10).ToString();
                this.label2.Text = r.Next(0, 10).ToString();
                this.label3.Text = r.Next(0, 10).ToString();
            }    
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Control.CheckForIllegalCrossThreadCalls = false;
        }
    }
