ThreadStart 与ParameterizedThreadStart的区别

1） ParameterizedThreadStart与ThreadStart

 1         static void Main(string[] args)
        {

            #region ParameterizedThreadStart第一种写法
            Thread thread = new Thread(new ParameterizedThreadStart(
                (s) => {

                    Console.WriteLine(s.ToString());
                }

                ));
            thread.Start("45   1");
            #endregion
            #region ParameterizedThreadStart第二种写法
            //把方法抽出WriteOut
            ParameterizedThreadStart parThread = new ParameterizedThreadStart(WriteOut);//WriteOut是方法
            Thread thread2 = new Thread(parThread);
            thread2.Start("3433343   2");

            #endregion

            #region ThreadStart第一种写法

            Thread thread3 = new Thread(new ThreadStart(
               () =>
               {

                   Console.WriteLine("ThreadStart里是没有参数的方法  3");
               }

               ));
            thread3.Start();//no parameter
            #endregion

            #region ThreadStart第2种写法

            Thread thread4 = new Thread(
               () =>
               {

                   Console.WriteLine("ThreadStart里是没有参数的方法222  4");
               }

               );
            thread4.Start();//no parameter
            #endregion
            Console.ReadKey();

        }

        private static void WriteOut(object obj)
        {
            Console.WriteLine(obj.ToString());
        }

输出结果顺序是不定的。

等等

2）ParameterizedThreadStart多个参数的传递

可以把多个值封装到一个类里进行传递

 class Program
    {
        static void Main(string[] args)
        {

            ParameterizedThreadStart paraThread = new ParameterizedThreadStart(AddTwoNumber);
            Thread thread = new Thread(paraThread);
            Number numbers = new Number();
            numbers.SetPare(1, 2);


            thread.Start(numbers);
            Console.ReadKey();

        }

        private static void AddTwoNumber(object obj)
        {//这里传过来一个类
            if (obj is Number)
            {
                Number num = (Number)obj;
                Console.WriteLine(num.First + " +" + num.Second+"=" +(num.First+num.Second));
            }
        }

    }

    class Number
    {
        private int first;
        private int second;
        public int First
        {

            get
            { return first;}

            set
            { first = value;}

        }
        public int Second
        {
            get { return second; }
            set { second = value; }
        }

        public void SetPare(int n, int m)
        {
            first = n;
            second = m;
        }

    }
