iwdu15,
Without more details, such as average & maximum # users, I would say a
Dictionary(Of User) would be a good start. Where User is your type that
maintains information about a specific user that is logged in.
However! you will want to consider using a thread safe wrapper around the
Dictionary(Of User)...
Note Dictionary(Of T) is a .NET 2.0 type, if you are using a previous
version of .NET I would suggest a HashTable.

Hi, im creating an application that will keep track of what users are
logged
into a network at a given time. all users must sign ingo this network
first,
so whenever a user is logged on, i will be notified. I am wondering on
what
the best collection will be. the number of users will vary (this is an AIM
like network) so it needs to be accessed quickly and efficiently. what is
the
best collection for this?
