c# 锁 Interlocked 操作

    //定义原子变量

  int mituxInt = -1;

//原子级别+1值,如果>=0,说明当前锁为空,可以执行,避免重复执行
if (Interlocked.Increment(ref mituxInt) <= 0)
            {

                if (_serverThread == null || (_serverThread.IsAlive == false))
                {
                    AutoConnect = isAutoConn;
                    _serverThread = new Thread(new ThreadStart(ThreadConnectServer));
                    _serverThread.IsBackground = true;
                    _serverThread.Start();
                }

                Interlocked.Exchange(ref mituxInt, -1);
            }

 

 

 

 

int lock2=0;

private void FuncMustDo()
        {
            //交换lock2 和1,返回lock2以前的值,这个和lock不一样的是,可以加其他条件
            while (Interlocked.Exchange(ref lock2, 1) != 0)
            {

            }
            //啪嗒啪嗒执行操作
//置0
            Thread.VolatileWrite(ref lock2, 0);//Thread.VolatileWrite执行一个原子写入操作，它的每次执行都具有释放语义
        }
