What is the importance of selecting extension methods?

Selecting extension methods is important because it allows developers to extend the functionality of existing classes without modifying their source code. This helps maintain the principle of code separation and keeps the original class clean and focused on its core responsibilities.

By selecting extension methods, developers can add new methods to existing classes, making them more versatile and adaptable to different scenarios. This promotes code reuse and modularity, as the extended functionality can be easily applied to multiple instances of the same class.

Furthermore, selecting extension methods provides a way to encapsulate common operations within a single reusable method, reducing code duplication. This leads to more maintainable and readable code, as developers can easily identify and utilize these extension methods in their programs.

Overall, the importance of selecting extension methods lies in promoting code reusability, modularity, and maintainability, while keeping the original class's source code intact.
