C Sharp (C#) - Interfaces

You need to design a plugin system where multiple unrelated classes must provide a Run() method. Which approach is best and why?

AUse an abstract class with Run() method to share common code among plugins.

BUse a concrete base class with Run() method to allow direct instantiation.

CUse an interface with Run() method to enforce the contract across unrelated classes.

DUse static classes with Run() methods for all plugins.

Step-by-Step Solution

Solution:

Step 1: Identify requirement for unrelated classes
Unrelated classes cannot share a common base class easily, so interface suits better.
Step 2: Evaluate options
Interface enforces Run() method without forcing inheritance, ideal for plugins.
Final Answer:
Use an interface with Run() method to enforce the contract across unrelated classes. -> Option C
Quick Check:
Interface suits unrelated classes needing common methods [OK]

Quick Trick: Use interface to enforce methods on unrelated classes [OK]
