How to Pick Abstract Class Or Interface in C#

In the intricate realm of C# programming, the decision to choose between an abstract class and an interface is a nuanced process that shapes the structure and behavior of software. As developers grapple with the task of designing robust and maintainable systems, the question arises: How to Pick Abstract Class or Interface in C#? This pivotal decision-making process involves a thoughtful evaluation of design goals, coding patterns, and the specific needs of the application at hand. Each choice, whether it be an abstract class or an interface, brings unique advantages and considerations to the table.

When to Use an Abstract Class and When to Use an Interface in C#

In C#, both abstract classes and interfaces provide mechanisms for defining contracts that classes must adhere to. However, there are key differences between the two, and the choice between using an abstract class or an interface depends on the design goals and requirements of your application.

Here are some guidelines to help you decide when to use an abstract class and when to use an interface:

Use an Abstract Class when?

1. Common Implementation: If you have a base class that contains common functionality shared among derived classes, an abstract class is a suitable choice. Abstract classes can provide a partial implementation of methods along with abstract members that must be…
