怎么做?新开一个线程做定时触发?

Question

private void Display()
        {
            Thread thisThread = Thread.CurrentThread;
            for (int i = 1; i <= 1000; i++)//这里可以设置一个永真的循环
            {
                Thread.Sleep(4000);//4秒触发一次
                Addtext(thisThread.Name + ":" + i.ToString());//具体触发什么自己写,
//如果要与界面打交道需要用到控件的InvokeRequired和Invoke()方法
            }
        }
               private void ThreadBtn_Click(object sender, EventArgs e)
        {
            Thread thread1 = new Thread(new ThreadStart(Display));
            thread1.Name="线程1";
            thread1.Start();        }
