What is the difference between generics and interfaces in C#?

Can you explain the difference between generics and interfaces in C#?

Sure! Generics allow you to define classes or methods with a placeholder for the data type, while interfaces define a contract that classes can implement.

Can you give me an example of how generics are used?

Of course! For instance, you can create a generic list like List<T> where T can be any data type, allowing for type safety.

And what about interfaces? How do they work?

Interfaces define methods and properties that implementing classes must provide. For example, an IShape interface could require a Draw method.

Are there situations where I should prefer one over the other?

Yes, use generics when you need type flexibility and safety, and use interfaces when you want to define a common behavior across different classes.
