Получите данные один раз от клиента и отобразите в окне сообщения

Question

Я отправляю данные с клиента на сервер, но сервер получает данные и периодически их отображает Обязательно: получение данных и агрегирование их в одну строковую переменную для их обработки (например, отображение в окне сообщения) .. .. .... .. .... .. .... .. .... .. ..

    public void WaitForData(System.Net.Sockets.Socket soc)

                // invoked when there is any write activity by the 
                // connected client
                pfnWorkerCallBack = new AsyncCallback(OnDataReceived);
            }
            SocketPacket theSocPkt = new SocketPacket();
            theSocPkt.m_currentSocket = soc;
            // Start receiving any data written by the connected client
            // asynchronously
            soc.BeginReceive(theSocPkt.dataBuffer, 0,
                               theSocPkt.dataBuffer.Length,
