ASP.NET in a Nutshell

Name

RemoveAll

Synopsis

Session.
                     RemoveAll( )

Removes all items from the Session collection.

Parameters

None

Example

The example checks to ensure that at least one item is in the Session collection (although if RemoveAll is called on an empty Session collection, no error will occur), and if it is, it clears the collection by calling the RemoveAll method:

Sub Page_Load(  )
   If Session.Count > 0 Then
      Session.RemoveAll(  )
      Message.Text = "Session collection cleared."
   Else
      Message.Text = "Session collection is already empty."
   End If
End Sub

Notes

The RemoveAll method is provided for backward compatibility with classic ASP. In classic ASP, this method was accessed through the Contents collection. In ASP.NET, this method can be accessed either directly, as shown above, or through the Contents collection.

RemoveAll has the same effect as calling the Clear method and like Clear, it clears the contents of the Session collection, but does not remove Session-scoped objects from the StaticObjects collection.
