.NET Forum / ASP.NET / Web Services / March 2005How does one debug .NET deserialization problems?
Why does .NET not issue messages or throw exceptions if it doesn't like something in the response from a web service?? I am getting a response object, but an array of custom objects within the response is null instead of being populated. The SOAP response from the service looks good and I cannot see anything wrong with the WSDL or XML schema. How do I get .NET to tell me what it doesn't like? Is there a way to turn on some kind of tracing or logging, or to get it to allow me to step into the deserialization code? You probably can in different ways... but I'd suggest u first use tcpTrace [0] and check the soap messages and see if they conform to schema (atleast visually); namespaces are right, elements are right.

SignatureHTH Regards, Dilip Krishnan MCAD, MCSD.net dkrishnan at geniant dot com http://www.geniant.com Thanks, but I already did that. I have a trace tool for the XML, and it looks fine and conformant to the schema. This is document literal, BTW. No weird soap encoding nonsense. > You probably can in different ways... but I'd suggest u first use > tcpTrace [0] and check the soap messages and see if they conform to [quoted text clipped - 9 lines] > > what it doesn't like?

Out of curiosity, did you also try taking your xml trace and writing a small lil console app that tries to deserialize the trace that you have into the expected type? > Thanks, but I already did that.
