从SMSC InteLab SMPP接收传递消息

Question

我已经尝试了几个星期但仍然无法弄清楚如何从SMSC发送短信后收到送达消息。我使用过Intelab SMPP并开发了一个短信系统。我使用以下代码来获取交货收据，我使用MessageId成功收到了收据。

public static IList<SubmitSmResp> ConnectToInet(string sourceAddress, string DestinationAddress, string Message)
    {
        try
        {
            SmppClient client = new SmppClient();
            IList<SubmitSmResp> respList = null;
            client.Connect(#SMSSeverIP, #PORT);

            if (client.Status == Inetlab.SMPP.Common.ConnectionStatus.Open)
            {
                client.Bind("USERNAME", "Password", Inetlab.SMPP.Common.ConnectionMode.Transceiver);

                if (client.Status == Inetlab.SMPP.Common.ConnectionStatus.Bound)
                {
                    client.AddrTon = 5;

                    respList = client.Submit(
                        SMS.ForSubmit().From(sourceAddress).To(DestinationAddress).Text(Message).DeliveryReceipt().Coding(DataCodings.Default)
                        );


                    //client.Submit(SMS.ForSubmit().Text(Message).From(sourceAddress).To(DestinationAddress).DeliveryReceipt().Coding(DataCodings.Default));

                    client.evDeliverSm += new Inetlab.SMPP.Common.DeliverSmEventHandler(OnDeliverSm);




                    client.UnBind();
                }

                client.Disconnect();
            }
            return respList;
        }
        catch (Exception ex)
        {
            throw ex;
        }


    }

我的DeliverSm方法用于获取送货回执，我已能够成功收到送货回执。

private static void OnDeliverSm(object sender, DeliverSm data)
    {
        string messageText = data.Client.GetMessageText(data.UserDataPdu.ShortMessage, data.DataCoding);
    }

我已经从每个SMSC响应中存储了收到的MessageId，我需要使用它来获取每条消息的相应发送报告，其中包含发送状态，发送日期和提交日期。有人可以帮我解决这个问题。谢谢你的帮助！
