Hi,
Inheritance is an element of object oriented programming that allows similar objects to inherit functionality and data from each other.
Interfaces define properties, methods, and events, which are the members of the interface. Interfaces contain only the declaration of the members. It is the responsibility of the deriving class to define the members.

Just go through below links. It is explained well -

Interfaces are a set of methods, properties, and other members that a target class
must implement.

Inheritance is the capability of a class to use the properties and methods of another
class while adding its own functionality. It Enables you to add new features and functionality
to an existing class without modifying the existing class.

Hi,
"
Class inheritance represents an "is-a" relationship, e.g., a Tank is a Vehicle. If your situation doesn't at least meet this, choose interface over inheritance.
If the proposed base class doesn't provide default implementations for your methods, this would be another reason to choose interface over inheritance.
In C#, you can only inherit from one class but multiple interfaces. This would be yet another reason to choose interface over inheritance.
