C# Define base class by

Question

I am trying to find a way to derive a class from a generic base class. Say:

sealed public class Final : Base
{

}

public class Base

        

Answer 1

I don't know the context of this question, but I ran into same question with a project where I had to make it possible to extend the base class which is already derived by many others. Like:

abstract class Base {}
class FinalA : Base {}
class FinalB : Base {}

// Now create extended base class and expect final classes to be extended as well:
class BetterBase : Base {}

The solution was to create common ancestor and connect through properties:

abstract class Foundation {}
abstract class Base : Foundation 
{
    Foundation Final { get; }
}
class FinalA : Foundation {}
class FinalB : Foundation {}
class FinalC : Foundation
{
    Foundation Base { get; }
}

// Here's the desired extension:
class BetterBase : Base {}

Now BetterBase has connection to final class and if needed, the final classes could have connection with (Better)Base also, as shown in FinalC class.
