This probably is a very noob question
What is the return type of Session("Something")?

I want to change:

        If Not Session("Name") Is Nothing Then
            LoginId = Session("Name").ToString

to something like

        MyObject = Session("Name")
        If Not MyObject Is Nothing Then
            LoginId = MyObject.ToString

Works, including the ToString call, which would be a polymorphic call
from a general reference I presume? Or is the Object type really a
Session Object type and not a general root for all Objects in VB, and
not like Object in Java?

Thanks a lot!

Every type is derived from type Object.

Object exposes a ToString() method therefore every type exposes a ToString()
method.

You can cast the returned object as type session:

Dim mySession As Session = CType(returnedObject, Session)

Hey, just to confirm, this is then a .NET property I think, not in VB
but in C# also, all objects are derived from type Object. Is that
correct?

As you might suggest, I am fairly new to .NET.

And thanks again, learned another little piece of .NET today.
