Generics were introduced for the first time in the. NET Framework 2.0. We can define generic interfaces, generic types, generic delegates, and generic methods.

A collection represents a combination of a set of objects that has an iterative (enumerable) attribute that can traverse each element of the collection through an iterative rule. Because the generic type and collection type have some
