多线程

//自定义线程数
int threadcount=3

//ThreadStart 委托 被委托对象为线程过程

            //初始数组中各线程，同时开启线程

            {
                threads[i] = new Thread(startAnylisis);
                threads[i].Start();
            }

上面是同事的，下面是我写的

 

static void Main(string[] args)

            //定义线程对象
            MyTask task1 = new MyTask("1");

            //打开线程

            //task2.m_thread.Start();

            Console.WriteLine("Press the Enter key to exit the program.");
            Console.ReadLine();
