The Session.Contents collection contains all of the items that have been established for a session. Information stored in the Session collections is available during a receiver session. The collection can be used to determine the value of a specific session item, or to iterate through the collection and retrieve a list of all items in the session. See the Collection Object for standard collection properties and methods.
Item = Session.Contents(key|index)

The Contents collection is the Session object implicit collection. Therefore you do not need to specify .Contents when accessing the collection.
