C#結合反射實現抽象工廠

抽象工廠，大名鼎鼎的設計模式之一，我這僅做了一個例子，來簡單記錄一下，先來類圖

具體代碼

namespace AbstractFactoryTest
{
    class Program
    {
        static void Main(string[] args)
        {  
            //具體工廠類型可以由配置文件中讀取
IFactory carFactory = CarFactory.CreateFacory("ThreadTest.AudiFactory");
            ICar car = carFactory.CreateCar();
            car.Run();

        }
    }

    public class CarFactory
    {
        public static IFactory CreateFacory(string factoryType)
        {
            Type t = Type.GetType(factoryType);
            return Activator.CreateInstance(t) as IFactory;
//另一種方法創建實體工廠對象Assembly.Load（程序集名稱).CreateInstance(命名空間.類名)
            //IFactory carFactory = Assembly.Load("ConsoleApplication2").CreateInstance(factoryType) as IFactory;
            //return carFactory;
        }
    }

    public interface IFactory
    {
        ICar CreateCar();
    }

    public class AudiFactory : IFactory
    {
        #region IFactory 成員

        public ICar CreateCar()
        {
            return new AudiCar();
        }

        #endregion
    }

    public class DasAutoFactory : IFactory
    {
        #region IFactory 成員

        public ICar CreateCar()
        {
            return new DasautoCar();
        }
        #endregion
    }






    public interface ICar
    {
        void Run();
    }
    public class AudiCar : ICar
    {
        #region ICar 成員

        public void Run()
        {
            Console.WriteLine("Audi.........");
        }

        #endregion
    }
    public class DasautoCar : ICar
    {
        #region ICar 成員

        public void Run()
        {
            Console.WriteLine("Dasauto.............");
        }

        #endregion
    }

}
