c# - Unexpected closing connection in transition data from wcf to client

Question

I use WCF service for implementing getting data from database (using Entity Framework and LINQ on the service side). But when the service returns data I receive error: The underlying connection was closed. The connection was closed unexpectedly. How can I bypass it ?

Answer 1

如果不返回强类型对象，则必须将其更改为强类型对象。当您返回一个对象时，它必须被序列化为 XML。并且序列化器不知道如何序列化一个类型object或匿名类型的对象，因为它不知道它必须序列化什么类型的对象或类的属性是什么等。
