　　二者的区别，跑一下下边的程序就懂了。

　　ManualResetEvent：通知一个或多个等待线程该事件已经发生。

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

 namespace Test01
 {
     class Program
     {
         private static ManualResetEvent mre = new ManualResetEvent(false);

         static void Main(string[] args)
         {
             for (int i = ; i < ; i++)
             {
                 Thread thread = new Thread(ThreadProc);
                 thread.Name = "Thread_" + i;
                 thread.Start();
             }

             Thread.Sleep();
             Console.WriteLine("If you want to release all threads. Please press 'Enter'.");
             Console.ReadLine();

             mre.Set();
             Console.WriteLine("All threads have been released.");
             mre.Reset();
         }

         private static void ThreadProc()
         {
             string threadName = Thread.CurrentThread.Name;

             Console.WriteLine("Thread: " + threadName + " starts and begin WaitOne().");
             mre.WaitOne();
             Console.WriteLine("Thread: " + threadName + " gets the signal and ends.");
         }
     }
 }

ManualResetEvent

　　AutoResetEvent：通知一个等待线程该事件已经发生。

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

 namespace Test02
 {
     class Program
     {
         private static AutoResetEvent are = new AutoResetEvent(false);

         static void Main(string[] args)
         {
             for (int i = ; i < ; i++)
             {
                 Thread thread = new Thread(ThreadProc);
                 thread.Name = "Thread_" + i;
                 thread.Start();
             }

             Thread.Sleep();

             Console.WriteLine("Please press Enter to release the signal.");
             Console.ReadLine();
             are.Set();
         }

         private static void ThreadProc()
         {
             string threadName = Thread.CurrentThread.Name;

             Console.WriteLine("Thread: " + threadName + " waits for AutoResetEvent.");
             are.WaitOne();
             Console.WriteLine("Thread: " + threadName + " gets the signal and is released.");
             are.Set();
         }
     }
 }
