When should I use generics in C#?

You should use generics in C# when you want to create classes, methods, or interfaces that can work with any data type while maintaining type safety.

Can you give me an example of a generic method?

Sure! Here's a simple example:

public T GetFirstElement<T>(List<T> list) {
    return list[0];
}

This method returns the first element of any list type.

What are the benefits of using generics?

The benefits include code reusability, type safety, and improved performance by reducing the need for boxing and unboxing.

Are there any downsides to using generics?

Yes, some downsides include increased complexity and potential performance overhead in certain scenarios, especially with constraints.
