What are the differences between generics and non-generics in C#?

What are the differences between generics and non-generics in C#?

Generics allow you to define classes, methods, and interfaces with a placeholder for the data type, while non-generics use specific data types. This means generics provide type safety and code reusability.

Can you give me an example of a generic class?

Sure! Here's a simple example of a generic class:

public class Box<T> {
    private T item;
    public void Pack(T item) {
        this.item = item;
    }
    public T Unpack() {
        return item;
    }
}

What are the advantages of using generics?

The advantages include type safety, reduced code duplication, and improved performance due to fewer boxing and unboxing operations.

Are there any downsides to using generics?

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