C#实现线程池的简单示例

using System;using System.Threading;//定义对象类，用以包装参数，实现多个参数的传递class Packet{ //成员属性包括两个输入参数和一个输出参数 protected internal String inval1; protected internal String inval2; protected internal String outval;}class ThreadPoolExam{ //定义执行相同内容的两个方法 public void Task1(object Obj) { //声明Packet类对象，用以传递参数 Packet PacketObj; PacketObj = (Packet)Obj; Console.WriteLine("任务一中的第一个输入参数：" + PacketObj.inval1); Console.WriteLine("任务一中的第二个输入参数：" + PacketObj.inval2); //为输出参数赋值 PacketObj.outval = PacketObj.inval1 + " " + PacketObj.inval2; } public void Task2(object Obj) { Packet PacketObj; PacketObj = (Packet)Obj; Console.WriteLine("任务二中的第一个输入参数：" + PacketObj.inval1); Console.WriteLine("任务二中的第二个输入参数：" + PacketObj.inval2);  PacketObj.outval = PacketObj.inval1 + " " + PacketObj.inval2; } static void Main() { //声明两个Packet对象，并为输入参数赋值 Packet PacketObj1 = new Packet(); Packet PacketObj2 = new Packet(); PacketObj1.inval1 = "Task 1 - 1"; PacketObj1.inval2 = "Task 1 - 2"; PacketObj2.inval1 = "Task 2 - 1"; PacketObj2.inval2 = "Task 2 - 2"; ThreadPoolExam tps = new ThreadPoolExam(); //将方法放入线程池的队列中 ThreadPool.QueueUserWorkItem(new WaitCallback(tps.Task1), PacketObj1); ThreadPool.QueueUserWorkItem(new WaitCallback(tps.Task2), PacketObj2); Console.ReadLine(); }}
