LINQ Help

Hi, I;m new to LINQ and need some help crwating a query.

I have 2 structures, 1 structure as follows;

Private Structure AA
Dim aName As String
Dim aCompany As String
Dim aSize as integer
End Structure

and I have another structure as follows;

Private Structure BB
Dim MyIndex As String
Dim bAddress As String
Dim aZip as integer
End Structure

I have 2 arrays Array0 of AA and Array1 of BB and what I need is the
interection of the array0 and array1 where aName in Array0 = MyIndex
in Array1.

Appreciate any help with this.

Cheers,
Dennis.
