Simple Question About Sending/Receiving Data To/From A Server

[C# Programming]

Good people,

I built an application that needs to send information to and receive it from a server. I have one questions, how do I do that? http://www.barakasoft.com/script/Forums/Images/smiley_laugh.gif

I am new to this aspect of programming.

Thanks for any information you can provide.
