What is the Constructor Chaining in C#?

Constructors play a crucial role in initializing objects and allocating memory within their respective classes. It is a requirement for every class to have at least one constructor. In object creation, Constructor Chaining refers to the practice of one constructor invoking another constructor within the same class or its base class.

'base' keyword

This mechanism establishes an implicit mapping between child class constructors and their corresponding parent class constructor, facilitated by the use of the 'base' keyword. Consequently, when an instance of a child class is instantiated, the parent class constructor is automatically invoked. This seamless inheritance process necessitates the presence of constructor chaining, without which inheritance between classes would not be feasible.
