Abrakadabra:

    class Program
    {
        static void Main(string[] args)
        {
            string type = KtoraKlaseAktywowac(); //Zwraca "A" albo "B"
            using (AQQ aqq = GetAQQPerType(type))
            {
                aqq.DoSomething();
            }
        }

        private static AQQ GetAQQPerType(string type)
        {
            switch (type)
            {
                case "A":
                    return new A();
                case "B":
                    return new B();
                default :
                    throw new InvalidOperationException("nieznany typ dla 
klasy AQQ");
            }
        }
    }
