C#结合反射实现抽象工厂

抽象工厂，大名鼎鼎的设计模式之一，我这仅做了一个例子，来简单记录一下，先来类图

具体代码

namespace AbstractFactoryTest
{
    class Program
    {
        static void Main(string[] args)
        {  
            //具体工厂类型可以由配置文件中读取
            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;

            //另一种方法创建实体工厂对象Assembly.Load（程序集名称).CreateInstance(命名空间.类名)
            //IFactory carFactory = Assembly.Load("ConsoleApplication2").CreateInstance(factoryType) as IFactory;
            //return carFactory;
        }
    }

    public interface IFactory
    {
        ICar CreateCar();
    }

    public class AudiFactory : IFactory
    {
        #region IFactory 成员

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

        #endregion
    }

    public class DasAutoFactory : IFactory
    {
        #region IFactory 成员

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






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

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

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

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

        #endregion
    }

}
