example documentation:

    public partial class addtocart : page {     protected void page_load(object sender, eventargs e)     {         string rawid = request["productid"];         int productid;         if (!string.isnullorempty(rawid) && int.tryparse(rawid, out productid))         {             using (shoppingcartactions usersshoppingcart = new shoppingcartactions())             {                 usersshoppingcart.addtocart(productid);             }         }         else         {             throw new exception("tried call addtocart.aspx without setting productid.");         }         response.redirect("shoppingcart.aspx");     } }
