C#中ManualResetEvent用法总结

　　class Program

　　{

　　static ManualResetEvent manualResetEvent = new ManualResetEvent(false);

　　static void Main(string[] args)

　　{

　　Task task = Task.Factory.StartNew(() =>

　　{

　　GetDataFromServer(1);

　　});

　　Task.Factory.StartNew(() =>

　　{

　　GetDataFromServer(2);

　　});

　　//Send first signal to get first set of data from server 1 and server 2

　　manualResetEvent.Set();

　　manualResetEvent.Reset();

　　Thread.Sleep(TimeSpan.FromSeconds(2));

　　//Send second signal to get second set of data from server 1 and server 2

　　manualResetEvent.Set();

　　Console.ReadLine();

　　/* Result

　　* I get first data from server1

　　* I get first data from server2

　　* I get second data from server1

　　* I get second data from server2

　　* All the data collected from server2

　　* All the data collected from server1

　　*/

　　}

　　static void GetDataFromServer(int serverNumber)

　　{

　　//Calling any webservice to get data

　　Console.WriteLine("I get first data from server" + serverNumber);

　　manualResetEvent.WaitOne();

　　Thread.Sleep(TimeSpan.FromSeconds(2));

　　Console.WriteLine("I get second data from server" + serverNumber);

　　manualResetEvent.WaitOne();

　　Console.WriteLine("All the data collected from server" + serverNumber);

　　}

　　}
