They are tad similar to C++ templates. With .net 1.0,
creating a flexible class or method that should use classes
that are known at compile time must be based on the object
class. With the object class, theres no type safety during
compile time. casting is necessary. Also, using the object
class for value types has a performance impact. .Net 2.0
supports generics, with generics the object class is no
longer necessary in such scenarios. Generic classes make
use of generic types that are replaced with specific types
as needed. This allows for typesafety. The
system.collections.Generic namespace gives you access to
generic versions of the stack, dictionary,
sorted dictionary, list and queue classes.
Advantages: Binary code reuse, performance, easy of
reading, typesafety.
