Abstract Factory - TechNet Articles - United States (English) - TechNet Wiki

Abstract factory is the extension of basic Factory pattern. It provides Factory interfaces for creating a family of related classes. In other words, here I am declaring interfaces for Factories, which will in turn work in similar fashion as with Factories.



public interface IFactory1

Abstract Factory

Abstract factory is the extension of basic Factory pattern. It provides Factory interfaces for creating a family of related classes. In other words, here I am declaring interfaces for Factories, which will in turn work in similar fashion as with Factories.



public interface
    {
        IPeople GetPeople();
    }
    public class Factory1 : IFactory1
    {
        public IPeople GetPeople()
        {
            return new Villagers();
        }
    }
 
    public interface IFactory2
    {
        IProduct GetProduct();
    }
    public class Factory2 : IFactory2
    {
        public IProduct GetProduct()
        {
            return new IPhone();
        }
    }
 
    public abstract class AbstractFactory12
    {
        public abstract IFactory1 GetFactory1();
        public abstract IFactory2 GetFactory2();
    }
 
    public class ConcreteFactory : AbstractFactory12
    {
 
        public override IFactory1 GetFactory1()
        {
            return new Factory1();
        }
        public override IFactory1 GetFactory1()
        {
            return new 
        public override IFactory2 GetFactory2()
        {
            return new Factory2();
        }
    }

The factory method is also implemented using common interface each of which returns objects.
