魔獸世界組隊(duì)下副本

下副本一般都要找5個(gè)人,一般玩家都在副本門口等,然后等待其他玩家跑過來(lái)

即玩家在做兩個(gè)動(dòng)作

1.跑到副本門口

2.等5個(gè)人到齊了，然后進(jìn)副本.

如果玩家先到就得等其他玩家到了才可以下副本，即大家跑到副本門口的時(shí)間是不同的，但進(jìn)副本的時(shí)間是相同的(保持線程同步).

示例代碼如下

public class Demo6 {Barrier barrier=new Barrier(5);public Demo6(){ThreadPool.QueueUserWorkItem(new WaitCallback(Task1));ThreadPool.QueueUserWorkItem(new WaitCallback(Task2));ThreadPool.QueueUserWorkItem(new WaitCallback(Task3));ThreadPool.QueueUserWorkItem(new WaitCallback(Task4));ThreadPool.QueueUserWorkItem(new WaitCallback(Task5));}public void Task1(object obj){Thread.Sleep(1000);Console.WriteLine(DateTime.Now);Console.WriteLine("Task1");barrier.SignalAndWait();Console.WriteLine("Task1 DoConcurrent");}public void Task2(object obj){Thread.Sleep(2000);Console.WriteLine(DateTime.Now);Console.WriteLine("Task2");barrier.SignalAndWait();Console.WriteLine("Task2 DoConcurrent");}public void Task3(object obj){Thread.Sleep(3000);Console.WriteLine(DateTime.Now);Console.WriteLine("Task3");barrier.SignalAndWait();Console.WriteLine("Task3 DoConcurrent");}public void Task4(object obj){Thread.Sleep(4000);Console.WriteLine(DateTime.Now);Console.WriteLine("Task4");barrier.SignalAndWait();Console.WriteLine("Task4 DoConcurrent");}public void Task5(object obj){Thread.Sleep(5000);Console.WriteLine(DateTime.Now);Console.WriteLine("Task5");barrier.SignalAndWait();Console.WriteLine("Task5 DoConcurrent");} }
