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。
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading; 6 using System.Threading.Tasks; 7 8 namespace Test01 9 { 10 class Program 11 { 12 private static ManualResetEvent mre = new ManualResetEvent(false); 13 14 static void Main(string[] args) 15 { 16 for (int i = 0; i < 3; i++) 17 { 18 Thread thread = new Thread(ThreadProc); 19 thread.Name = "Thread_" + i; 20 thread.Start(); 21 } 22 23 Thread.Sleep(100); 24 Console.WriteLine("If you want to release all threads. Please press 'Enter'."); 25 Console.ReadLine(); 26 27 mre.Set(); 28 Console.WriteLine("All threads have been released."); 29 mre.Reset(); 30 } 31 32 private static void ThreadProc() 33 { 34 string threadName = Thread.CurrentThread.Name; 35 36 Console.WriteLine("Thread: " + threadName + " starts and begin WaitOne()."); 37 mre.WaitOne(); 38 Console.WriteLine("Thread: " + threadName + " gets the signal and ends."); 39 } 40 } 41 }
