What is generic and nongeneric in C#?
A Generic collection is a class that provides type safety without having to derive from a base collection type and implement type-specific members. A Non-generic collection is a specialized class for data storage and retrieval that provides support for stacks, queues, lists and hashtables.
Why we are using collections in C#?
Collection classes serve various purposes, such as allocating memory dynamically to elements and accessing a list of items on the basis of an index etc. These classes create collections of objects of the Object class, which is the base class for all data types in C#.
