C# Generics problem

Question

Hi,

I have a problem dealing with Generics.  

Some background:

The Animal class is a generified class that needs to be associated with a particular person

Dog is an animal that can only be associated with the class Doctor (a subclass of Person)

Cat is an animal that can only be associated with the class Painter (a subclass of Person)

I need a method (named SomeMethod) that will take in new lists of animals

SomeMethod will primarily deal with the Owner property from the Animal class

using System.Collections.Generic;

namespace Test

{

    class Program

    {

        static void Main()

        {

            SomeMethod(new List<Animal<Person>>(), new List<Dog>());

        }

        public static void SomeMethod<T>(IList<Animal<T>> a, IList<Animal<T>> b)

            where T : Person

        {

            //do something

        }

    }

    class Animal<T>

        where T : Person

    {

        public T Owner { get; set; }

    }

    class Dog : Animal<Doctor>

    {

    

    }

    class Cat : Animal<Painter>

    {

        

    }

    class Person

    {

    

    }

    class Doctor : Person

    {

    

    }

    class Painter : Person

    {

        

    }

}

Would anybody have an idea?
