                    Print(param);

            Console.Read();
 
        }
 
        private static void Print(object param)
        {
            var p = (Tuple<string, AutoResetEvent>)param;
            Console.WriteLine(Thread.CurrentThread.Name + ": Begin!");
            Console.WriteLine(Thread.CurrentThread.Name + ": Print" + p.Item1);
            Thread.Sleep(300);
            Console.WriteLine(Thread.CurrentThread.Name + ": End!");
            p.Item2.Set();
        }
    }
}

一次性地Set,其实使用ManualResetEvent就足够了。
