Why are you sending a data object reader to your business logic? I think if you have maintained a clear separation between data layer and business layer its not a good idea to send data reader to business layer.

You don't really explain what's your problem. I'm sure that passing objects around is no issue here. So what's your concern? Separation? Improve your question, explain what problems are you facing, include some code to make it clear.

May I ask why you want to pass a reader all the way from data access layer to presentation layer? I mean you can convert the sqldatareader to datatable or Generic Collection etc. in Business Object Layer and use the same in presentation layer. I am not sure that you are also making use of Data Transfer Objects or Business Entities, if so you can return the List/Collection or DTO/BE from Business Object Layer and use it in Presentation Layer

Instead of passing the datareader return the actual data to the presentation layer. Even better approach is to box the data in Object type and then un-box that Object in the specific type you require in the presentation layer.
