Accepting datasets as parameters to webservice

[JeffC]

I've created a web service with a method that accepts a string and a dataset
as parameters. I've created the proxy class and written a .ASPX page to call
it. The code in the .ASPX loads some test data into the dataset and calls
the proxy class. The Web Service starts up, the string has the data from the
call in the .ASPX page, but the contents of the dataset parameter is
"Undefined." How can I see where the dataset got "lost"?

A little more information:

1) There are three methods in this web service. One of them accepts only a
dataset as a parameter, and that seems to arrive fine. The one that accepts
a string and a dataset doesn't get the dataset.

2) I've put a SOAP debugger (basically a proxy that intercepts the request
and response) in line and found that the dataset is indeed in the request.

I'm also using a custom SOAP header (on all three methods) to provide
authentication.

I found out what I was doing wrong. I changed the name of the parameter
after I generated the proxy class. Hence, the name in the XML was "ds", but
the new name of the parameter in the C# source was "dsP". When I renamed the
parameter back to "ds", it was no longer undefined.
