How to pass variables between ASP.net pages?
The easiest way is to just use a Querystring variable.





int MyNumber = 5;





Response.Redirect(String.Format("page2... MyNumber));





To retrieve a querystring variable, simply use Request.QueryString("VariableName");





You could also place your variables in hidden form fields and use Request.Form() to retrieve them.





Some people find it easiest to simply store them as session variables, but I find this to be rather inefficient and a poor practice.
