In this Article I will explain about Generics Feature with some examples.

Generics

Generics are used to help make the code in the software components much more reusable. They are a type of data structure that contains code that remains the same. The data type of the parameters can change with each use.The usage within the data structure adapts to the different data type of the passed variables.

Each time the generic is used, it can be customized for different data types without needing to rewrite any of the internal code. Generics permit classes, structs, interfaces, delegates, and methods to be parameterized by the types of data they store and manipulate.

We can refer to a class, where we don't force it to be related to any specific Type, but we can still perform work with it in a Type-Safe manner. An example where we could implement Generics is in dealing with collections of items (integers, strings, Orders etc.). We can create a generic collection than can handle any Type in a generic and Type-Safe manner. For example, we can have a single array class to store a list of Users or even a list of Items, and when we actually use it, we will be able to access the items in the collection directly as a list of Users or Items, and not as objects (with boxing/unboxing, casting).
