unique arrays

[Paulers]

Hello all, I just picked up my virst vb.net book last weekend and Im
hooked. Can anyone tell my if there is a way to keep array elements
unique? Or possibly in another data collection that might have that
characteristic, Im not bound to arrays. I have been searching all over
the net including groups.google.com and I can't find any information.

If you use a dictionary, then the keys have to be unique and this is enforced.

Hi,

To expand on what Anand says. I would use an HashTable. Here
is a link to some info on it.

\\\
Dim ht As New Hashtable()
Dim o1 As New Object()
Dim o2 As New Object()
ht.Add(o1, o1)
MsgBox(ht.Contains(o1))
MsgBox(ht.Contains(o2))

Thanks you very much for all your help. I really appreciate it. I will
take a look at HashTables.
