//线程

public  class MyProccess
        {
            public  void Start()
            {
                ThreadStart start=new ThreadStart(ThreadAction);
                Thread th=new Thread(start);
                th.IsBackground = true;
                th.Start();
            }

            public void ThreadAction()
            {
                while (true)
                {
                    try
                    {
                        //do something
                        System.Threading.Thread.Sleep(30000);
                    }
                    catch (Exception)
                    {

                        throw;
                    }
                }
            }
        }

//多线程

static void MyMain()
        {
            WaitCallback callBack;
            callBack = new WaitCallback(PooledFunc);
            WaitCallback callBack2;
            callBack2 = new WaitCallback(PooledFunc2);
            WaitCallback callBack3;
            callBack3 = new WaitCallback(PooledFunc3);
            ThreadPool.QueueUserWorkItem(callBack,
               "Is there any screw left?");
            Console.WriteLine("Main thread. Is pool thread: {0}, Hash: {1}", Thread.CurrentThread.IsThreadPoolThread, Thread.CurrentThread.GetHashCode());
            ThreadPool.QueueUserWorkItem(callBack2);
            Console.WriteLine("Main thread. Is pool thread: {0}, Hash: {1}", Thread.CurrentThread.IsThreadPoolThread, Thread.CurrentThread.GetHashCode());
            ThreadPool.QueueUserWorkItem(callBack3,
               "Decrease stock of monkey wrench");
            Console.WriteLine("Main thread. Is pool thread: {0}, Hash: {1}",Thread.CurrentThread.IsThreadPoolThread,Thread.CurrentThread.GetHashCode());
            Console.ReadLine();
        }

        static void PooledFunc(object state)
        {
            while (true)
            {
                Console.WriteLine("Processing request ‘{0}‘." +" Is pool thread: {1}, Hash: {2}",(string)state, Thread.CurrentThread.IsThreadPoolThread,Thread.CurrentThread.GetHashCode());
                // Simulation of processing time
                Thread.Sleep(10000);
            }

            Console.WriteLine("Request processed");
        }

        static void PooledFunc2(object state)
        {
            while (true)
            {
                Console.WriteLine("Processing request How much is a 40W bulb?." + " Is pool thread: {0}, Hash: {1}", Thread.CurrentThread.IsThreadPoolThread, Thread.CurrentThread.GetHashCode());
                // Simulation of processing time
                Thread.Sleep(5000);
            }

            Console.WriteLine("Request processed");
        }
        static void PooledFunc3(object state)
        {
            while (true)
            {
                Console.WriteLine("Processing request This is PooledFunc3." + " Is pool thread: {0}, Hash: {1}", Thread.CurrentThread.IsThreadPoolThread, Thread.CurrentThread.GetHashCode());
                // Simulation of processing time
                Thread.Sleep(9000);
            }

Console.WriteLine("Request processed");
}

多线程就相当于自己写好函数委托给系统的线程池帮忙照顾

线程就是自己创建添加委托启动

定时器我的理解是算是又一次封装的线程？

补充，线程池

while(start)

{

if(flg)

{

Thread.Sleep(100);

}
