示例1: Mutex

// This example shows how a Mutex is used to synchronize access
// to a protected resource. Unlike Monitor, Mutex can be used with
// WaitHandle.WaitAll and WaitAny, and can be passed across
// AppDomain boundaries.
 
using System;
using System.Threading;

class Test
{
    // Create a new Mutex. The creating thread does not own the
    // Mutex.
    private static Mutex mut = new Mutex();
    private const int numIterations = 1;
    private const int numThreads = 3;

    static void Main()
    {
        // Create the threads that will use the protected resource.
        for(int i = 0; i < numThreads; i++)
        {
            Thread myThread = new Thread(new ThreadStart(MyThreadProc));
            myThread.Name = String.Format("Thread{0}", i + 1);
            myThread.Start();
        }

        // The main thread exits, but the application continues to
        // run until all foreground threads have exited.
    }

    private static void MyThreadProc()
    {
        for(int i = 0; i < numIterations; i++)
        {
            UseResource();
        }
    }

    // This method represents a resource that must be synchronized
    // so that only one thread at a time can enter.
    private static void UseResource()
    {
        // Wait until it is safe to enter.
        mut.WaitOne();

        Console.WriteLine("{0} has entered the protected area", 
            Thread.CurrentThread.Name);

        // Place code to access non-reentrant resources here.

        // Simulate some work.
        Thread.Sleep(500);

        Console.WriteLine("{0} is leaving the protected area\r\n", 
            Thread.CurrentThread.Name);
         
        // Release the Mutex.
        mut.ReleaseMutex();
    }
}

示例2: Mutex

//引入命名空间
using System;
using System.Threading;

class Example
{
    // Create a new Mutex. The creating thread does not own the mutex.
    private static Mutex mut = new Mutex();
    private const int numIterations = 1;
    private const int numThreads = 3;

    static void Main()
    {
        Example ex = new Example();
        ex.StartThreads();
    }

     private void StartThreads()
     {
        // Create the threads that will use the protected resource.
        for(int i = 0; i < numThreads; i++)
        {
            Thread newThread = new Thread(new ThreadStart(ThreadProc));
            newThread.Name = String.Format("Thread{0}", i + 1);
            newThread.Start();
        }

        // The main thread returns to Main and exits, but the application continues to
        // run until all foreground threads have exited.
    }

    private static void ThreadProc()
    {
        for(int i = 0; i < numIterations; i++)
        {
            UseResource();
        }
    }

    // This method represents a resource that must be synchronized
    // so that only one thread at a time can enter.
    private static void UseResource()
    {
        // Wait until it is safe to enter, and do not enter if the request times out.
        Console.WriteLine("{0} is requesting the mutex", Thread.CurrentThread.Name);
        if (mut.WaitOne(1000)) {
           Console.WriteLine("{0} has entered the protected area", 
               Thread.CurrentThread.Name);
   
           // Place code to access non-reentrant resources here.
   
           // Simulate some work.
           Thread.Sleep(5000);
   
           Console.WriteLine("{0} is leaving the protected area", 
               Thread.CurrentThread.Name);
   
           // Release the Mutex.
              mut.ReleaseMutex();
           Console.WriteLine("{0} has released the mutex", 
                             Thread.CurrentThread.Name);
        }
        else {
           Console.WriteLine("{0} will not acquire the mutex", 
                             Thread.CurrentThread.Name);
        }
    }

    ~Example()
    {
       mut.Dispose();
    }
}

输出:

Thread1 is requesting the mutex
Thread1 has entered the protected area
Thread2 is requesting the mutex
Thread3 is requesting the mutex
Thread2 will not acquire the mutex
Thread3 will not acquire the mutex
Thread1 is leaving the protected area
Thread1 has released the mutex

示例3: Mutex.ReleaseMutex()

//引入命名空间

using System.Threading;

class MainClass {
    public static void Main() {
        bool ownsMutex;
        using (Mutex mutex = new Mutex(true, "MutexExample", out ownsMutex)) {
            if (ownsMutex) {
                Console.ReadLine();
                mutex.ReleaseMutex();
            } else {
                Console.WriteLine("Another instance of this application " +
                    " already owns the mutex named MutexExample.");
            }
        }
