AutoResetEvent vs ManualResetEvent

This 2 is a signaling methodology. E.g. you have 2 thread , Thread 2 can call Thread 1 stop in middle, and call thread 1 continue run again later.

AutoResetEvent

Only allow 1 Thread to run, if u have 3 WaitOne(), you need to have 3 Set().

ManualResetEvent

Allow all Thread to run, if u have 3 WaitOne(), you only need to have 1 Set().

// static AutoResetEvent objAuto = new AutoResetEvent(false);

static ManualResetEvent objAuto = new ManualResetEvent(false);

static void Main(string[] args)

{

    new Thread(SomeMethod).Start();

    Console.WriteLine("Main");

    Console.ReadLine();

    objAuto.Set();

    Console.ReadLine();

    objAuto.Set();

    Console.ReadLine();

}

static void SomeMethod()

{

    Console.WriteLine("Start 1");

    objAuto.WaitOne();

    Console.WriteLine("Finish 1");

    Console.WriteLine("Start 2");

    objAuto.WaitOne();

    Console.WriteLine("Finish 2");

}



Result (Auto)

------
Main
Start 1
(Enter)
Finish 1
Start 2
(Enter)
Finish 2

Result (Manual)
------
Main
Start 1
(Enter)
Finish 1
Start 2
Finish 2
