namespace 线程池判断结束综合演示
{
    class Program
    {
        public static int iCount = 0;　　
        public static int MaxCount = 10;//允许线程池中运行最多10个线程 
        static ManualResetEvent eventX = new ManualResetEvent(false);  //新建ManualResetEvent对象并且初始化为无信号状态

static void Main(string[] args)
        {
            Console.WriteLine("ManualResetEvent初始为无信号状态 ");
            Console.WriteLine("线程池最大值为 {0} 个线程。", MaxCount);
            for (int iItem = 1; iItem <= MaxCount; iItem++)
            {
                //插入队列元素
                Console.WriteLine("加入线程 {0}", iItem);
                ThreadPool.QueueUserWorkItem(new WaitCallback(fun1), (object)iItem);
            }
            Console.WriteLine("等待线程池完成操作。。。"); //等待事件的完成，即线程调用ManualResetEvent.Set()方法
            eventX.WaitOne(Timeout.Infinite, true); //WaitOne()方法使调用它的线程等待直到eventX.Set()方法被调用
            Console.WriteLine("线程池结束！");
            Console.ReadLine(); 
        }

public static void fun1(object j)
        {
