stop website from loading after a catch and show error. Inside a class

Question

Hi I am having a problem with a Try and Catch in a Web Application pretty much the problem is: I have my function to open a port if the reader is not connected then it will catch it but I am not sure on the following: Showing the error in a label (when working from inside a class) and how to stop the WebApp from finishing loading so it doesn't load the rest of the code. I can't use Java because of Users Requirements so this is why I am a bit stuck as MessageBox doesn't exist anymore. Many Thanks

No Problem Friend when you call a Function From Page just pass the Page Instance as Perimeter to Function so you can Call Redirect From Function Like Below if I call Function() from Page1 and Function Contain Redirect code. and you need to add name space for Accessing Page Object if my answer helps you then please check Do you like this answer check box please :) using System.Web.UI; Page1 Code ------------------------- protected void Page_Load( object sender EventArgs e) { try { } catch { //Pass Page Object in function Parameter Class1 .Function( this .Page); } } Class1 Code ---------------- public class Class1 { public static void Function( Page p) { p.Response.Redirect( Error.aspx  true ); } }

I can't find the namespace for Response under a class I tried creating it but I seem to be having a problem as I am inside a class not a webform
