c# Monitor.wait() 和sleep的区别

1  区别:

a 、 moniter 继承的积累为object，sleep 继承 thread 类

b、moniter.wait()，会阻塞线程，阻塞的同时但会释放锁，再次获得锁的时候，需要monitor.Pulse唤醒

c、 thread.sleep 是当前的线程休眠，时间到后，自动恢复 继续往下执行

例如：

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace Wait和Sleep
{
    class Program
    {



        static object locker = new object();
        static Thread thread1 = new Thread(TestTwo);
        static void Main(string[] args)
        {

            Thread thread = new Thread(TestWait);
            thread.Start();
            lock (locker)
            {
                Console.WriteLine($"线程拥有锁");
                Console.WriteLine($"线程开始休眠");
                for (int i = 0; i < 3; i++)
                {
                    Thread.Sleep(1000);
                    Console.WriteLine($"Main{i}");
                }
                Console.WriteLine($"线程休眠结束");
            }
            Console.ReadLine();
        }

        static void TestWait()
        {
            Console.WriteLine($"TestWait");

            //这里会等待locker 释放
            lock (locker)
            {
                Console.WriteLine($"开始wait");
                thread1.Start();
                Console.WriteLine($"开始wait并且释放锁，阻塞当前线程向下执行，直到再一次获取锁");
                var satus = Monitor.Wait(locker, 2000); //释放对象上的锁并阻止当前线程，直到它重新获取该锁。 如果已用指定的超时时间间隔，则线程进入就绪队列。
                if (!satus)
                {

                    Monitor.Pulse(locker);//
                    Console.WriteLine("TestWait通知完成");
                    break;
