What is an interface in C#?

An interface in C# is a contract that defines a set of methods and properties that a class must implement.

Can you give me an example of how to create an interface?

Sure! Here's a simple example:

public interface IAnimal
{
    void Speak();
}

How do classes implement this interface?

Classes implement an interface using the : symbol. For example:

public class Dog : IAnimal
{
    public void Speak()
    {
        Console.WriteLine("Woof!");
    }
}

What are the benefits of using interfaces?

Interfaces promote a clean separation of concerns, enable polymorphism, and allow for more flexible code.
