C17_11 執行緒集區的例子 OperThread.cs

        iMaxCount = MaxCount;
    }
    //執行緒集區裡的執行緒將叫用Beta方法
    public void Beta(Object state)

        //輸出當前執行緒的Hash編碼值和Cookie的值
        Console.WriteLine(" {0} {1} : ", Thread.CurrentThread.GetHashCode(), ((StateInfo)state).Cookie);

        lock (HashCount)

        }
        Thread.Sleep(2000);
        //Interlocked.Increment() 操作是一個原子操作
        Interlocked.Increment(ref iCount);
