Listing Web Services parameters

Hello,

Is it possible to list parameters and their types when you are using
[WebMethod (Description ()] tag or any else tag?

I couldn't find any lineseparator characters to Description attribute
when I was trying
to list parameters in hardcoded way. All parameters came is one big
line.

So, how should I list Web Methods parameteters if I like to show them
to user?
Such situations are e.g. when user or programmer pressed F5 or ctrl-F5
in Visua Studio
when the Web Service project is open and (s)he want to test Web
Service.

Any ideas?

Cheers!
