Exploring the Role of the "new" Keyword in Method Signatures

In the realm of coding, encountering unfamiliar syntax can often trigger curiosity. One such instance is the inclusion of the "new" keyword within a method signature. In this article, we delving into its significance and explore its nuances.

What Does the "new" Keyword Signify?

The "new" keyword appearing within a method signature implies a specific behavior. It allows a method to behave as an overriding method, even when the method it replaces is not declared as virtual within the base class. This enables developers to modify the implementation of non-virtual or static methods without the need for explicit virtual declarations.

Distinguishing "new" from "override"

While both "new" and "override" aim to provide a mechanism for method overrides, their application differs. "override" is solely employed to replace virtual methods, ensuring adherence to the Liskov Substitution Principle, which stipulates that derived classes should not alter the behavior of base class methods. In contrast, "new" extends this ability to non-virtual and static methods, offering greater flexibility in method implementation.
