#620 – Inherit from a Class In A Different Assembly

You can create a new class that inherits from a class that exists in another assembly (e.g. in a class library), as long as the parent class is public (and not sealed).

Let’s assume that someone gives you a copy of DogLibrary.dll, which includes two classes–a Dog class, which is defined as public and a DogMath class, which is defined as internal.

In another program, you can inherit from the Dog class, as long as you add a reference to the DogLibrary assembly.

You inherit from the Dog class just like you inherit from a class within your own program.

    public class Program
    {
        public class CrazyDog : Dog
        {
            public override void Bark()
            {
                Console.WriteLine("Grrrowfffpermuckledoodleweeeheehee!");
            }
        }

        static void Main()
        {
            CrazyDog myDog = new CrazyDog();
            myDog.Bark();
        }
    }
