The .NET Library for excel which i use after reading good and positive response from users is Aspose.Cells for .NET. It has been a year and a half that i am using this Library and so far i haven't got any problem and their support team is very good. It allows you to create, read, edit, and convert excel file to many other formats. It is not free but offers free trial so you can try this Library if you haven't found any good library for excel.

I agree on your first part. But I have some disagreement with 2nd viz. For abstract factory...I think the carpenter would still be the one making doors...but for installing a door, only a door is not enough...you need hinges, knobs, handles, stoppers, nails etc. So we would have a NailFactory, KnobFactory, HandleFactory etc. to make a complete door. So the abstract factory would be solely responsible for making complete doors with the help of NailFactory, HandleFactory etc.

Two question if you can answer: 1 . Factory design pattern gives one object.. Abstract Factory gives you factories .. What if we need multiple products of one type.. like 5 plastic doors.. would we be making abstract factory in this case?
