Answer Posted / purushottam.ambati@gmail.
Generics is a concept introduced in .NET 2.0 and these are
just like templates in C++. Using generics we can create
classes,methods,events, delegates which work with any type
(like int,string,myclass etc). In .NET 2.0,
System.Collections.Generic namesapce was introduced and it
contains classes/interfaces related to generics. Advantages
are Performance, Code Reuse, Type Safety.
we can create generic classes (which work with any type)
in .NET 1.1 by using System.Object class. But, it requires
type casting, boxing and unboxing operations internally.
these operations are very expensive. so performace of
application will degrade.
