I think the original problem was that you were expecting the array to be populated with instances of MessageClass. My VB is rusty but I still don't understand the second code line above. Thought you'd need something like this:

        Dim MyBuiltMessage As MessageClass() = New MessageClass(1) {}
        MyBuiltMessage(0) = New MessageClass()

        MyBuiltMessage(0).Property1 = "Hello"
        MyBuiltMessage(0).Property2 = 1

But anyway as long as it's working :-}
