I currently have working C# code that queries a database based on a last name. What I want to do now is pass an inputted variable (such as from a text box) from an ASP.NET webpage to this C# code.
So the user will place the last name in a textbox on the webpage, and once submit is pressed I want to send that last name to the C# code...can anyone help out?

What do you have so far?

You need a web form with a textbox on it and button to fire off the process.

yeh ive got that...what i am trying to figure out is how to i get the ASP.NET page to pass this variable into the C# code and run the C# code as a whole? Is there a certain spot in the aspx.cs file where i can put my code? I know it is kind of hard to understand what I mean, but if i can just figure a way to get ASP.NET to run C# code I would be golden

ASP.NET can run C# code, so I'm not sure what you are asking. The codebehind of a C# page can access the controls that you have put on the page. You refer to them by the controlid you provided in the control markup (<asp:textbox runat="server" id="txtLastName" />).
