Property Value

Type: System.Web.SessionStateHttpSessionState
An HttpSessionState representing the ASP.NET session state object for the current session.

The example below uses session state to determine how many times a particular session accesses the XML Web service method SessionHitCounter. In this example, the EnableSession property of the WebMethodAttribute is set to true in order to gain access to session state.
