c# 鎖 Interlocked 操作

    //定義原子變數

  int mituxInt = -1;

//原子級別+1值,如果>=0,說明當前鎖為空,可以執行,避免重覆執行
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()
        {
            //交換lock2 和1,返回lock2以前的值,這個和lock不一樣的是,可以加其他條件
            while (Interlocked.Exchange(ref lock2, 1) != 0)
            {

            }
            //啪嗒啪嗒執行操作
//置0
            Thread.VolatileWrite(ref lock2, 0);//Thread.VolatileWrite執行一個原子寫入操作，它的每次執行都具有釋放語義
        }
