C#多线程同步事件及等待句柄
最近捣鼓了一下多线程的同步问题，发现其实C#关于多线程同步事件处理还是很灵活，这里主要写一下，自己测试的一些代码，涉及到了AutoResetEvent 和 ManualResetEvent，当然还有也简要提了一下System.Threading.WaitHandle.WaitOne 、System.Threading.WaitHandle.WaitAny和System.Threading.WaitHandle.WaitAll ，下面我们一最初学者的角度来看，多线程之间的同步。
假设有这样的一个场景，主线程开了一个子线程，让子线程等着，等主线程完成了某件事情时再通知子线程去往下执行，这里关键就在于这个怎让子线程等着，主线程怎通知子线程，一般情况下我们不难想到用一个公共变量，于是咱们就有了下面的代码：
using System;using System.Collections.Generic;using System.Text;using System.Threading;namespace AutoResetEventTest{ class Program { const int numIterations = 10; static AutoResetEvent myResetEvent = new AutoResetEvent(false); static AutoResetEvent ChangeEvent = new AutoResetEvent(false); //static ManualResetEvent myResetEvent = new ManualResetEvent(false); //static ManualResetEvent ChangeEvent = new ManualResetEvent(false); static int number; //这是关键资源 static void Main() { Thread payMoneyThread = new Thread(new ThreadStart(PayMoneyProc)); payMoneyThread.Name = "付钱线程"; Thread getBookThread = new Thread(new ThreadStart(GetBookProc)); getBookThread.Name = "取书线程"; payMoneyThread.Start(); getBookThread.Start(); for (int i = 1; i <= numIterations; i++) { Console.WriteLine("买书线程：数量{0}", i); number = i; //Signal that a value has been written. myResetEvent.Set(); //ChangeEvent.Set(); Thread.Sleep(10); } payMoneyThread.Abort(); getBookThread.Abort(); } static void PayMoneyProc() { while (true) { myResetEvent.WaitOne(); //myResetEvent.Reset(); Console.WriteLine("{0}：数量{1}", Thread.CurrentThread.Name, number); ChangeEvent.Set(); } } static void GetBookProc() { while (true) { ChangeEvent.WaitOne(); //ChangeEvent.Reset(); Console.WriteLine("{0}：数量{1}", Thread.CurrentThread.Name, number); Console.WriteLine("------------------------------------------"); //Thread.Sleep(0); } } }}本文部分资料来源于网络，特此声明！
