C# 线程学习记录

1. 线程的创建，启动，暂停，恢复和中止；

Thread th = new Thread(ThreadMethod);  // 创建线程

        static void ThreadMethod()
        {
            while(true)
            {
                Console.WriteLine("Thread executing......
");
                Thread.Sleep(1000);
            }
        }

        static void Main(string[] args)
        {
            Console.WriteLine("Main start...
");
            Thread th = new Thread(ThreadMethod);  // 创建线程
            th.Start();    // 启动线程
            for (int i = 0; i < 10; i++)
            {
                if (i == 3)
                    th.Suspend();   // 挂起线程
                if (i == 5)
                    th.Resume();   // 继续线程
                if (i == 7)
                    th.Abort();    // 中止线程
                Console.WriteLine(i + "
");
                Thread.Sleep(1000);
            }
            Console.WriteLine("Main end 
");
            Console.ReadLine();
        }

Suspend 和 Resume 提示如下信息：

修复该提示，新增一个 AutoResetEvent，修改代码如下：

class Program
    {
        private static bool State = true;
        static AutoResetEvent ResetThr = new AutoResetEvent(false);

        public static void Stop()
        {
            State = false;
        }
        public static void Continue()
        {
            State = true;
            ResetThr.Set();
        }
        public static void Add()
        {
            while (true)
            {
                for (int i = 0; i < 1000; i++)
                {
                    if (!State)
                    {
                        ResetThr.WaitOne();
                        //// to suspend thread.
                        //ResetThr.Reset();
                    }
                    if(i==20)
                    {
                        Stop();
                        Console.WriteLine("Stop thread");
                    }
                    Console.WriteLine(i);
                    Thread.Sleep(500);
                    i++;
                }
            }
        }
        static void ThreadMethod()
        {
            while(true)
            {
                if (!State)
                {
                    Thread.Sleep(3000);
                    Continue();
                    Console.WriteLine("Resume thread");
                }
                Console.WriteLine("Thread executing......");
                Thread.Sleep(1000);
            }
        }

        static void Main(string[] args)
        {
            Console.WriteLine("Main start...");
            Thread th = new Thread(ThreadMethod);  // 创建线程
            Thread th2 = new Thread(Add);
            th2.Start();
            th.Start();    // 启动线程
            Console.WriteLine("Main end");
            Console.ReadLine();
        }
    }
