Using generics in abstract classes

Question

I\'m working on an abstract class where the implementing class needs to implement a list of T. The problem is that this doesn\'t work:

public class AbstractC         


        

Answer 1

1. You need to mark AbstractClass abstract, because it contains abstract property

2. Specify the generic type in the AbstractClass declaration

3. Implement abstract property with override

public abstract class AbstractClass
{
    public int Id { get; set; }
    public int Name { get; set; }

    public abstract List Items { get; set; }
}

public class Container : AbstractClass
{
    public override List Items { get; set; }
}
