此處介紹一下 AutoResetEvent的方法

下面貼一下微軟自帶的一個方法讯泣。

using System;
using System.Threading;

class ZLP_TEST
{
    static AutoResetEvent autoEvent = new AutoResetEvent(false);

    static void Main()
    {
        Console.WriteLine("Main starting.");

        ThreadPool.QueueUserWorkItem(
            new WaitCallback(WorkMethod), autoEvent);

        // Wait for work method to signal.
        autoEvent.WaitOne();
        Console.WriteLine("Work method signaled.\nMain ending.");
        Console.ReadKey();
    }

    static void WorkMethod(object stateInfo) 
    {
        Console.WriteLine("Work starting.");

        // Simulate time spent working.
        Thread.Sleep(10000);
        
        // Signal that work is finished.
        Console.WriteLine("Work ending.");
        ((AutoResetEvent)stateInfo).Set();
    }
}

我們會注意到里面有個方法

ThreadPool.QueueUserWorkItem(
            new WaitCallback(WorkMethod), autoEvent);

此處這個方法可以替換帶參數(shù)啟動一個new Thread昨稼。 上面這個方法已經(jīng)非常簡練假栓，建議這么使用，下面這個方法挺繁瑣的匾荆。
下面的方法其實也是帶參數(shù)新建線程的一個方法杆烁。

我們先新建一個類

public class Test
        {
            AutoResetEvent autoEvent;
            public Test(AutoResetEvent autoevent)
            {
                autoEvent = autoevent;
            }
            public void WorkMethod()
            {
                Console.WriteLine("Work starting.");

                // Simulate time spent working.
                Thread.Sleep(10000);

              
                // Signal that work is finished.
                Console.WriteLine("Work ending.");
                ((AutoResetEvent)autoEvent).Set();
            }

        }

那么將原先工程中的替換一下

using System;
using System.Threading;

class ZLP_TEST
{
    static AutoResetEvent autoEvent = new AutoResetEvent(false);

    static void Main()
    {
        Console.WriteLine("Main starting.");
        //原先的做法
        //ThreadPool.QueueUserWorkItem(
           // new WaitCallback(WorkMethod), autoEvent);
        //目前的做法
            Test a = new Test(autoEvent);
            Thread b = new Thread(new ThreadStart(a.WorkMethod));
            b.Start();
        // Wait for work method to signal.
        autoEvent.WaitOne();
        Console.WriteLine("Work method signaled.\nMain ending.");
        Console.ReadKey();
    }

    static void WorkMethod(object stateInfo) 
    {
        Console.WriteLine("Work starting.");

        // Simulate time spent working.
        Thread.Sleep(10000);
        
        // Signal that work is finished.
        Console.WriteLine("Work ending.");
        ((AutoResetEvent)stateInfo).Set();
    }
}
