Hi,

I am buidling a usercontrol to comsume a webservice.

The wsdl can be found here. It is very easy to generate a proxy (or what is the correct term?) using wsdl.exe. So far it works perfectly.

However, the methods that are exposed through the wsdl do not allow me to retrieve the data as xml, the only output I can get back comes in the form of an array of results that I can get back as strings to work with... This is quite inconvenient.

I know for a fact that it is possible to get the raw xml data back from the webservice because some online generic Soap clients give me xml output but I do not know enough about Soap to know how to get to the xml myself.

I googled around a bit but the only articles about webservice consumption I could find focused on using wsdl.exe and the methods it builds from the wsdl.

I probably need to do something with the output of the Invoke method... but again, I am not at all a soap expert so I don't know where to start...

I will include the code generated by wsdl.exe for good measure;

Code:
