Accessing State in ASP.NET

Question

Is

System.Web.HttpContext.Current.Session

the same as

System.Web.UI.Page.Session

?

Many thanks in advance.

Answer 1

Yup; they refer to the same instance.

Answer 2

There is no difference between the two.

Answer 3

They do indeed refer to the same instance, but if you look at the methods in Reflector, you can see that they behave a bit differently (in ways that are not likely to matter in most applications):

• The call to Page.Session uses a cached HttpSessionState reference.
• The Page method will throw if session state is not enabled, while HttpSessionState.Session just returns whatever is in the "AspSession" bucket of its Items collection.
