Solution 1

Write this in code behind to get the value of query string field.

C#

string prodId = Request.QueryString["product_id"];

In ASP.NET, convention is to always use var instead of data type. Anyways, 4ed for your answer. :-)

No, that's just resharper telling you (wrongly) that you should use var :) Looking at his code I know prodId is a string, if it was "var" then how do I know what is being returned just by looking at it?

True, but everything in the query string is a string. You don't expect a file to be appended in the URL? ;-) Would you? :laugh:

That's only because you know what QueryString returns from experience. Someone new to the code won't know just from looking at your code. var is merely a compiler mnemonic that gets replaced with the proper variable name, all you're doing is adding confusion by using var.
