多线程三种传值方式

记下，以备后查.

static void TestThread4()
        {
            //1.直接写方法
            Thread t1 = new Thread(PrintMessage);
            t1.Start("Test Thread1");
            //2.使用ParameterizedthreadStart
            Thread t2 = new Thread(new ParameterizedThreadStart(PrintMessage));

            t2.Start("Test Thread2");
            //3. 使用Lambda
            Thread t3 = new Thread(() => Print("Test Thread3"));
            t3.Start();
            //4.使用匿名函数
            Thread t4 = new Thread(delegate() { Print("Test thread4"); });
            t4.Start();
        }

        //只能为Object,只能有一个参数
        static void PrintMessage(object msg)
        {
            string sMsg = (string)msg;
            Console.WriteLine(sMsg);
            Thread.Sleep(500);
        }

        static void Print(string msg)
        {
            Console.WriteLine(msg);
            Thread.Sleep(500);
        }
