You would need to use SOAP serialization. Please see:
http://msdn.microsoft.com/en-us/library/90c86ass%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.soap.soapformatter%28v=vs.110%29.aspx[^].

However, I don't understand why would you need to work at so low level. How about using Service Contract where you would work not even with the data, but immediately with the interface and its methods? Please see:
http://msdn.microsoft.com/en-us/library/bb412196%28v=vs.110%29.aspx[^].

In this case, more difficult work with SOAP you could leave to non-.NET client, if you even needed it.

3q very much

Does it mean "tricky"? Your writing it tricky. :-) (And the use of Service Contract is simple, compared to the attempt to create a soap message on low level.)
Are you going to accept the answer formally?

From your information, it's unclear what could be wrong.
