Questions

[asifmaniar]

i found the following 2 questions in one of the question banks but can't seem to find an answer. Can anyone please help. Thanks. Questions - 1)In C#, what are the trade-offs that you should consider between interfaces and inheritance when designing for polymorphic behavior? 2)What are the advantages and disadvantages of streaming APIs like SAX, and ADO.NET’s Datareader vs non streaming APIs like the XML DOM and the ADO.NET Dataset?

All I can say for 1, is that you can only inherit from one type, so if there is a posibility that you may want to inherit from a particular type, use an interface instead.
