多线程同步

在Main方法里在. 我一次性要开10个线程, 十个线程跑同一个方法, 但方法传入的参数不同, 等这十个线程都跑完了, 接下来再做Main方法里其他的事情

转载的:

我有个想法
设定一个变量t，当新建一个线程时t+1，线程完成时t-1，
线程完成时调用一个委托，
在委托方法中通过判断t是否等于0来确定所有线程是否执行完毕

在main中通过do while t <> 0来判断也可以……

 

 

这是第二种方法. 但没有测试过.

 

 

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.Threading; 
using System.Collections.ObjectModel; 

namespace ThreadControler 
{ 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            m_ResultInfoList=new Collection <string>(); 
            Collection <Thread> threadList=new Collection <Thread>(); 
            for (int i = 0; i < 10; i++) 
            { 
                Thread workThread = new Thread(new ParameterizedThreadStart(TestThreadProc)); 
                threadList.Add(workThread); 
                workThread.Start(i); 
            } 
            m_ThreadReadyEvent.Set(); 
            foreach (Thread tempThread in threadList) 
            { 
                tempThread.Join(); 
            } 
            foreach (String tempResult in m_ResultInfoList) 
            { 
                Console.WriteLine(tempResult); 
            } 
            Thread.Sleep(5000); 
        } 
        private static Mutex m_ResultListMutex = new Mutex(); 
        private static Collection <String> m_ResultInfoList=null; 
        private static EventWaitHandle m_ThreadReadyEvent = new EventWaitHandle(false, EventResetMode.ManualReset); 
        private static void TestThreadProc(Object index) 
        { 
            m_ThreadReadyEvent.WaitOne(); 
            for (int i = 0; i < 5; i++) 
            { 
                Thread.Sleep(500); 
            } 
            m_ResultListMutex.WaitOne(); 
            m_ResultInfoList.Add(index.ToString()); 
            m_ResultListMutex.ReleaseMutex(); 
        } 
    } 
} 

 

 

下面这个测试过. 可以用.
