passing collection object to web service in .NET

[vbvjain]

I am developing an applocation which reads mails in outlook inbo
alongwith attachments and all these informmation is stored in
collection which i need to pass it to a web service, which will perfor
certain operations on that collection and then return that modifie
collection to the client.
but when i am trying to pass a simple collection of strings to my we
service it gives me an error "You must implement Add(System.Object) a
it inherits from IColletion".
Can someone tell me the exact way as to how i can pass collection t
and from a web service in VB.NET

Thanks in advanc
