I have a Web service that I'm developing that I'm trying to make as
easy as possible to use.

In my main app (which won't be using the service), I have an account
object class, which in turn has a collection of a business object
class.  This is how I'm keeping the appropriate businesses with the
correct user account.

I've been trying to accomplish this in the Web services, but I'm not
having very good luck.  I was able to serialize the collection, but in
order to add a business to it I have to ReDim and Preserve the business
collection: ReDim Preserve account.BusinessCollection(1)
account.BusinessCollection(1) = New MyService.Business

Is there a better way?

The client app needs to read, modify, add the account and business
objects.
