Synchronized InfoPath Attachment With Document Library

I have an InfoPath 2010 form with a Document attachment.

if any user upload infopath form with attachment, than attachment must be added in document library,

if any user modify or delete any attachment form infopath library than that document must be update or delete from document library.

• if any user modify or delete any document(s) in document library then that document(s) must be update / delete in infopath form also.

Can anyone guide me how can I perform this using C# programmatically

Thanks in Advance
