Chain of Responsibility Pattern - DESIGN PATTERNS (C#/.NET)

Learn about the chain of responsibility pattern, which is a behavioral design pattern where the client passes a request through a chain of handlers. This pattern is helpful for decoupling the client from the specifics of how a request is handled.
Design patterns are important for implementing object-oriented designs and adhering to SOLID principles. Understanding these fundamental patterns helps software developers build clean and maintainable applications.

Thanks

That's a good one, but can you please do with the DI? Because, currently you are passing the next handler directly but what if I have 3 or 4 handlers? Like H1 - H2 - H3 - H4. How should I manage this with DI? Also, what if each handler takes different types of arguments? The best example is a restaurant menu.

Good questions! I think even with DI, you'd have to manually resolve and pass in each handler, especially since they all implement the same interface.
Also, I would usually use this pattern if all the handlers take the same arguments. This makes the chain flexible, where we can re-order the different handlers without worrying about type issues.

Thanx. Can we use the Factory method?
