            }

        static void Main(string[] args)
        {

            newThread.Start();

            for (int j = 0; j < 200; j++)
            {
                if (j == 60)
                {
                    newThread.Join();
                }
                else

线程的jion：

在线程A中调用线程B的jion方法，线程A暂停执行，一直执行完线程B然后才执行线程A。

在A线程中创建线程B，然后启动线程B，当执行线程B的jion方法后，A线程将被阻塞，只执行B线程，一直等到B线程执行完毕，才继续执行A线程。

线程B可以再A中创建，也可以不在A中创建。
