Yes,

In ASP.Net the web page generation works in context of an instance of the HttpApplication object.

In a page or a custom control these are available implicitly as they're included as properties within the base objects these item inherit from.

Out of context of such pages you can find the current http execution context here:

C#

System.Web.HttpContext.Current

This object includes instances of HttpSessionState, HttpRequest, HttpResponse and many other things.

To access these and have them properly initialised you must be working within a web project and have the System.Web assembly referenced.

Thanks a lot for answer. And which are the explicit object then? The ones which we derive from user defined classes? Ex MyClass myObj1=new MyClass().
Is myObj1 is Explict object???

I don't think implicit and explicit are really the terms you need to apply to your question. At some point within the framework everything is defined explicitly. What you have in object oriented designed is inheritance. When you create a page, Session, Request and Response are inherited but they're still explicitly defined within the class you're inheriting from.
