Answer 1

代码不完整，你什么时候改变过num值的，这里没有体现。

Answer 2

详细代码，问题是：不使用  Console.read();   readText()方法会在多线程中间就执行，而不是等多线程执行完在执行，请各位大神指点迷津using System;

Answer 3

OK，我看明白了，你num的确没改变过，而且一直是2，原先还以为你的num会是0呢，因为默认情况下都是0.
下面就是看你代码执行线程了，假定你的主线程ID为1，那么action方法就是在线程1中执行的，进入内部分支判断后进入到num=2的分支，然后还是线程1中执行Control();，但是在Control方法内部又新开了几个线程，ID分别为2、3、4、5……，总之不可能在线程1上执行了，然后等那几个线程开始后，Control执行结束，线程1执行下面的readText方法，这不是很明显的多线程并行执行吗？谁都不会妨碍谁。

Answer 4

但如果不加console.read();则readText()方法会在2,3,4,5...其中一个后面执行，而不是等2.3.4.5.。z执行完在执行

Answer 5

你要等待，看这个：http://bbs.csdn.net/topics/390373347

Answer 6

使用fastCSharp程序流程大概是这样子
        public void action()
        {
            switch (num)
            {
                case 2:
                    using (control()) readText();
                    break;
            }
        }
        private fastCSharp.threading.task control()
        {
            fastCSharp.threading.task task = new fastCSharp.threading.task(threadNO);
            foreach (string url in listUrl)
            {
                NewThread thread1 = new NewThread(listUrl[j], int.Parse(urlNo) + 25);
                task.Add(thread1.OutputN);
            }
            return task;
        }
