Novice Requires Help - Web Reference - Classes

Question

Hi,

I'm new to C# and need to make a Web Reference, this I've done and I can see the Class.

How do I make a reference to it in my code, do I use 'using .....'?

In the example of code for using it I have the following line: -

cpLatestBrief.authValue

there is now reference to 'cpLatestBrief', what should I do to correct this?

Hope this makes sense?

Regards
