Object in Global.asax

Hi Phan, Your code does the same what I'd shown. As session has got an indexer, you can add and retrieve the session value as: Session[string Name or int Index] = value; // adding session value = Session[string Name or int Index]; // retrieving session and as Session is recognized from anywhere in an ASP.NET application, there's no need to use the lengthy name i.e. HttpContext.Current.Session. Same is with the Application object. There's basically no side effects of using session in your application, except performance. For performance tips in your .net applications check this article: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/dotnetperftips.asp Cheers, Yasser

hi yasser, thanks alot, i fix this problem by these code. HttpContext.Current.Session.Add(string Name, object value); obj = (object) HttpContext.Current.Session[string Name]; pls tell me. what side effect can occure?

//Create a object MyClass myClass = new MyClass(); //Add it to Session or Application Session["objSession"] = myClass; // putting MyClass object to Session Application["objApplication"] = myClass; //putting MyClass object to Application //retrieve back the Session or Application value MyClass newobjSess = (MyClass)Session["objSession"]; // retrieving session MyClass newobjApp = (MyClass)Application["objApplication"]; // retrieving Application Cheers, Yasser
