C# app call to ASP.NET web page

[guy]

Hi,

I need to make a call from my C# application to an ASP.NET web page and pass
some parameters to it and receive back a return value.

Anybody know what the class/function name is in C# to do this?

I'm looking for something like:
string xxx = "http://www.myweb.com/test.aspx?param1=aaa&param2=bbb";
int result = GetWebResult(xxx);

Thanks

You'd be better off if you put called a web service
instead of a web page.

With a webpage you will have to grab the entire page and
parse it, while with a web service you can return only
those values you want.

Can you give me an example of webservice that I can load to my web that I
can experiment with?

Or perhaps if I'm more specific you can point me in the right direction:
From my app, I'd like to call
www.example.com/auth.aspx?lic=234234&user=134123

and have that aspx page do a DB lookup to verify that the license on the
user's machine is current.

Do you think a web service is better for this?

Thanks.

I do not have any webservices that I can give you, but
take a look at:
http://www.codeproject.com/cs/webservices/myservice.asp
for a guide to making your own web service, it's pretty
easy to do.

In short, a webservice as far as your code is concerned
(after you've built the reference with the automatic
tools), is just another class that you would instantiate
and make a call to a member of.

On the server, it is not unlike standard class library,
you have functions with parameters that are called, do
their work and return a value.
