1.有参无返回
2.等到所有线程都执行完毕后，再执行主线程

class Program
{
    static List<ManualResetEvent> manualResetEvents = new List<ManualResetEvent>();
    static void Main(string[] args)
    {
        try
        {
            ThreadPool.SetMinThreads(3, 3);
            for (int i = 0; i < 10; i++)
            {
                Tesla tesla = new Tesla();
                tesla.mre = new ManualResetEvent(false);
                tesla.Model_S = "Model S " + i;
                tesla.Model_3 = i;
                tesla.Model_X = DateTime.Now;
                if (i / 2 == 0)
                {
                    tesla.Model_Y = true;
                }
                else
                {
                    tesla.Model_Y = false;
                }
                manualResetEvents.Add(tesla.mre);// 这一步重要 一定需要将参数对象添加到List中,当方法执行完成的时候会修改为true
                ThreadPool.QueueUserWorkItem(BiliBili, tesla);// 将方法排入多线程队列,线程可用时执行
            }
            WaitHandle.WaitAll(manualResetEvents.ToArray());// 最多支持64线程
            Console.WriteLine("结束了");
        }
        catch (Exception e)
        {
            Console.WriteLine("Error:" + e.Message);
        }
        finally
        {
            Console.ReadKey();
        }
    }

    static void BiliBili(object obj)
    {
        Tesla tesla = obj as Tesla;

        Console.WriteLine(tesla.Model_3 + " return:Model_S=" + tesla.Model_S + " Model_3=Model 3 " + tesla.Model_3 + " Model_X=" + tesla.Model_X + " Model_Y=" + tesla.Model_Y + " | 线程ID:" + Thread.CurrentThread.ManagedThreadId);
        Thread.Sleep(2500);
        if (tesla.Model_3 / 2 == 0)
        {
            Thread.Sleep(5000);
            //int d = 10 / tesla.Model_3;
        }

        tesla.mre.Set();//发送信号量 本线程执行完毕 / 重要
    }
}
