描述：在线程执行结束后，通过委托来执行下一步的逻辑

C#代码如下：

        /// <summary>
        /// 定义一个带参数的委托
        /// </summary>
        /// <param name="sender"></param>
        protected delegate void ThreadCallBack(object sender);

        static void Main(string[] args)
        {
            ThreadCallBack _ThreadCallBack = new ThreadCallBack(CallBackTest); //创建一个委托
            Thread _Thread = new Thread(ThreadRun); //实例化一个线程
            _Thread.Start(_ThreadCallBack); //启动线程并将委托作为参数传入

            Thread.Sleep(1000);
            _ThreadCallBack = new ThreadCallBack(CallBackTest); //创建一个委托
            _Thread = new Thread(ThreadRun); //实例化一个线程
            _Thread.Start(_ThreadCallBack); //启动线程并将委托作为参数传入

            Thread.Sleep(1000);
            _ThreadCallBack = new ThreadCallBack(CallBackTest); //创建一个委托
            _Thread = new Thread(ThreadRun); //实例化一个线程
            _Thread.Start(_ThreadCallBack); //启动线程并将委托作为参数传入
        }
        /// <summary>
        /// 线程执行
        /// </summary>
        /// <param name="sender"></param>
        static void ThreadRun(object sender)
        {
            //添加业务逻辑
            //TODO

            //测试
            for (int i = 5; i >= 0; i--)
            {
                Console.WriteLine("线程" + Thread.CurrentThread.ManagedThreadId + "等待时间：" + i + "秒");
                Thread.Sleep(1000);
            }

            (sender as ThreadCallBack)(Thread.CurrentThread.ManagedThreadId);
        }
        /// <summary>
        /// 委托对应的方法
        /// </summary>
        /// <param name="sender"></param>
        static void CallBackTest(object sender)
        {
            Console.WriteLine("线程" + sender.ToString() + "执行结束");
            Console.ReadLine();
        }
