Question

民间，

我遇到了以下异常，我知道这不是一个超时问题，而是一个消息大小问题。只使用CommunicationException，有没有办法告诉这个问题是邮件大小问题而不是超时问题？也许是CommunicationException的一个属性？或者它可以以某种方式投射？我愿意探索任何提案。

System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '24.11:30:00'. ---> System.IO.IOException: The read operation failed, see inner exception. ---> System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '24.11:30:00'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

似乎没有一种好方法可以做到这一点。

我是否可以仅使用CommunicationException来区分超时和消息大小问题？
