我使用Jamaa Lib和Jamaa Net成功实施了一个应用程序。感谢开发人员。
但是当我使用异步发送操作时，我遇到了问题。正在不断提出未处理的异常。如果有人能帮助我找出问题，我将不胜感激。
请注意。我正在使用相同的应用程序接收和发送短信。我需要每天平均发送100,000条短信。同时我也收到SMSC的短信。提前致谢。

以下是该应用引发的异常。

您可以尝试使用wireshark来查看原始数据包，这样可以让您了解出现了什么问题。在我的情况下，它是一个无效的系统ID。
答案 1 :(得分：0)
您可能需要检查您的凭据，还需要添加以下语句：
client.Properties.InterfaceVersion = InterfaceVersion.v34;
client.Properties.DefaultEncoding = DataCoding.SMSCDefault;
client.Properties.SourceAddress = "XXXXX";
client.Properties.AddressNpi = NumberingPlanIndicator.Unknown;
client.Properties.AddressTon = TypeOfNumber.Unknown;
client.Properties.SystemType = "XXXX";
client.Properties.DefaultServiceType = ServiceType.DEFAULT;
它将帮助您，并且一定会消除此异常。 如果您认为此答案有用，请标记它。
