我怎么知道队列结束时我的线程消耗了MQ消息

Question

我需要使用来自MQ队列的消息，然后在最终确定队列使用时关闭控制台应用程序。我不知道消息何时在队列中。我能够成功完成读取，但是我不知道何时结束队列消耗就离开线程了。我需要知道如何识别这一刻。

    this.connection = cf.CreateConnection();

        this.connection.ExceptionListener = new ExceptionListener(this.OnException);

        this.session = this.connection.CreateSession(true, AcknowledgeMode.AutoAcknowledge); // sessão com controle de transação

        IDestination destQueue = this.session.CreateQueue(filaMensagem);

        this.consumer = this.session.CreateConsumer(destQueue);

        // Create an AutoResetEvent for signalling between threads
        using (this.receiveCompleteEvent = new AutoResetEvent(false))
        {
            // Create and register the listener
            this.consumer.MessageListener = new MessageListener(this.OnNewMessageCallback); // Callback for message handling

            // Start the connection
            this.connection.Start();

            // Block and wait for the receiveCompleteEvent event to be signalled.
            this.receiveCompleteEvent.WaitOne();
        }

        // dispose receiveCompleteEvent
        this.consumer.Close();

        this.session.Close();

        this.connection.Close();
