How do generics improve code reusability in C#?

Can you explain how generics improve code reusability in C#?

Generics allow you to define classes, methods, and interfaces with a placeholder for the data type, enabling code reuse for different types without sacrificing type safety.

Can you give me an example of generics in action?

Sure! For instance, you can create a generic List<T> class that can hold any data type, like List<int> for integers or List<string> for strings, without needing separate implementations.

What are the benefits of using generics over non-generic collections?

Generics provide type safety, reduce the need for casting, and improve performance by avoiding boxing and unboxing for value types.

Are there any downsides to using generics?

One downside is that generics can lead to more complex code and may be harder to understand for beginners. Additionally, they cannot be used with certain types like non-parameterless constructors.
