Object in Global.asax

Question

hi all, pls tell me, how to creat object (my own class or dataset). And use session and application level.

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
