C# 使用 AutoResetEvent 或 ManualResetEvent 同步两个线程

    class Program
    {
        // 信号

                Console.WriteLine("{1} Write i : {0}", i, (string)state);
                ar.Set();
            }

            // 线程池方法
            ThreadPool.QueueUserWorkItem(WriteMethod,"Write Thread ");

            // 普通开线程方法
            //Thread write = new Thread(new ThreadStart(WriteMethod));
            //write.Name = "Write Thread ";

            // 如果是后台线程,需要 一个 Console.ReadKey 等待
            //write.IsBackground = true;
            //write.Start();

            // 开启 读取线程
            // 线程池方法
            ThreadPool.QueueUserWorkItem(ReadMethod,"Read Thread ");

            // 普通开线程方法
            //Thread read = new Thread(new ThreadStart(ReadMethod));
            //read.Name = "Read Thread ";

            // 如果是后台线程,需要 一个 Console.ReadKey 等待
            //read.IsBackground = true;
            //read.Start();

            // 如果使用线程池方法的时候.线程都是 后台线程. Console 会立即结束.所以需要这个方法来阻塞主线程
            Console.ReadKey();
        }
    }
