I need to call a generic stateless oracle webservice from a c# .Net 4.0 windows application. The webservice will be used to query the validity of 2 numbers and must return a valid/invalid message or something similar. The application users must login to the webservice with valid credentials at the start of the process. The webservice method I am using is called CustomObject2Query. I have downloaded the wsdl.

I have read the small amount of material that I can find on this, including the oracle webservices manual and the sample code, but I still don't understand what to do.

Can anyone provide sample code (or even a list of the steps to take) that shows how to login, query and return a value from a stateless Oracle webservice, or alternately point me at something that will.

All help would be appreciated as I am running out of time to complete the application.
