Hello, and thank you for posting on the Microsoft Interoperability Forum. However, this forum is intended to be a discussion area for people who have questions about the Microsoft Interoperability Initiative, which covers interoperability for Producs, Access to documentation, APIs, Protocols, Commitment to Standards, and collaboration with industry groups.
As for your question there is a very helpful community on the MSDN
ASMX Web Services and XML Serialization forum that may be able to assist you with your solution. I suggest you post your question to that forum by clicking here:
