线程同步中使用信号量AutoResetEvent

using System;
using System.Threading;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
var p = new Program();
p.Do();
p.Signal();
}

AutoResetEvent autoResetEvent = new AutoResetEvent(false); //false代表默认中阻塞状态

void Do()
{
var worker = new Thread(() =>
{
Console.WriteLine("Start worker");
Console.WriteLine("wait");
autoResetEvent.WaitOne(); //等待信号
Console.WriteLine("do");
});
worker.Start();
}

void Signal()
{
Console.WriteLine("Sent signal");
Console.ReadKey();
autoResetEvent.Set(); //发送信号
Console.ReadKey();
}
}
}
