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。

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(, );

             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;
         }

     }
