C#Thread同步Mutex的代码详解-木庄网络博客

首先Mutx m = new Mutex();

在一个函数中 m.WaitOne();

然后 m.ReleaseMutex();

在另一个函数中同样 m.WaitOne();

m.ReleaseMutex();

你要写的只能一个进程访问的代码段就放在m.WaitOne();和m.ReleaseMutex();中间

private Mutex mutF = new Mutex();  
        private Mutex mutH = new Mutex();  
           
        private void ReadF()  
        {  
            mutF.WaitOne();  
           // your code to access the resource              
            mutF.ReleaseMutex();  
        }  
   
        private void ReadH()  
        {  
            mutH.WaitOne();  
   
            // your code to access the resource  
            mutH.ReleaseMutex();  
        }  
   
   
        private void Form1_Load(object sender, EventArgs e)  
        {  
   
            Thread tF = new Thread(new ThreadStart(ReadF));  
            Thread tH = new Thread(new ThreadStart(ReadH));  
            tFlower.Start();  
            tH.Start();  
               
            mutF.WaitOne();  
            mutH.WaitOne();  
            // your code to access the resource  
            Thread.Sleep(1000);  
            mutH.ReleaseMutex();  
            mutF.ReleaseMutex();  
}
