我只是尝试对互斥和写了下面的代码。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace Mutex_WaitOnewithTimeouts
{
class Program
{
private static Mutex mut = new Mutex();
private static int numOfThreads = 5;
private static int numOfIterations = 3;
private static Random rand = new Random();
static void Main(string[] args)
{
Thread[] threads = new Thread[5];
for (int num = 0; num < numOfThreads; num++)
{
threads[num] = new Thread(new ThreadStart(MyThreadProc));
threads[num].Name = String.Format("Thread{0}", num);
threads[num].Start();
}
Console.Read();
}
private static void MyThreadProc()
{
for (int iteration = 0; iteration < numOfIterations; iteration++)
{
UseResource();
}
}
private static void UseResource()
{
Console.WriteLine("{0} accessing ", Thread.CurrentThread.Name);
int time = (int)(rand.NextDouble() * 100);
try
{
if (mut.WaitOne(time))
{
Console.WriteLine("Yippie got mutex for {0}", Thread.CurrentThread.Name);
Thread.Sleep((int)rand.NextDouble() * 5000);
}
else
{
Console.WriteLine("Nopee.... Timeout occured for {0}", Thread.CurrentThread.Name);
}
}
catch (AbandonedMutexException ex)
{
Console.WriteLine(" Exception is caught");
}
finally
{
Console.WriteLine("Releasing mutex for {0}", Thread.CurrentThread.Name);
mut.ReleaseMutex();
}
}
}
}
但我有时会收到ApplicationException的..一个人可以帮我,如果有什么错我的代码,也请将这个异常触发时解释。
对象同步方法是从代码不同步块调用。 试图释放互斥锁时,我finally块中得到这个。
