C# 设计模式巩固 - 抽象工厂模式

　前言

　   继续工厂模式高级版，抽象工厂模式。抽象工厂模式其实是从工厂方法模式拓展而来。在实际的生活中一个工厂的产品不可能是单一的，肯定是多种系列的产品。

　介绍 - 抽象工厂模式

　　定义：(摘自百度百科~)为创建一组相关或相互依赖的对象提供一个接口，而且无需指定他们的具体类。

　实现

　　继续上一篇的某淘鞋厂的例子。现在鞋厂的生意越做越大甚至还开了分厂，老板现在决定拓展业务，买衣服...夏天买T-Shirt，冬天买棉衣，下面看实现：

1.衣服

　　/// 

    /// 衣服基类
    /// 
    public abstract class Clothes
    {
        public abstract string Name { get; }
    }
    /// 

    /// T恤衫
    /// 
    public class TShirt : Clothes
    {
        public override string Name
        {
            get
            {
                return "T恤衫";
            }
        }
    }
    /// 

    /// 夹克衫
    /// 
    public class Jacket : Clothes
    {
        public override string Name
        {
            get
            {
                return "夹克衫";
            }
        }
    }

2.鞋子

/// 

    /// 鞋子基类
    /// 
    public abstract class Shoes
    {
        public abstract string Name { get; }
    }

    /// 

    /// 凉鞋
    /// 
    public class Sandal : Shoes
    {
        public override string Name
        {
            get
            {
                return "凉鞋";
            }
        }
    }
    /// 

    /// 棉鞋
    /// 
    public class CottonPaddedShoes : Shoes
    {
        public override string Name
        {
            get
            {
                return "棉鞋";
            }
        }
    }

3.工厂

/// 

    /// 抽象工厂类
    /// 
    public abstract class Factory
    {
        /// 

        /// 生产鞋子
        /// 
        /// 
        public abstract Shoes CreateShoes();
        /// 

        /// 生成衣服
        /// 
        /// 
        public abstract Clothes CreateClothes();
    }
    /// 

    /// 夏季工厂类
    /// 
    public class SummerFactory : Factory
    {
        public override Clothes CreateClothes()
        {
            return  new TShirt();
        }

        public override Shoes CreateShoes()
        {
            return new Sandal();
        }
    }
    /// 

    /// 冬季工厂类
    /// 
    public class WinterFactory : Factory
    {
        public override Clothes CreateClothes()
        {
            return new Jacket();
        }

        public override Shoes CreateShoes()
        {
            return new CottonPaddedShoes();
        }
    }

调用：

　　class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("夏季工厂生产...");
            //夏季工厂
            Factory factory = new SummerFactory();
            //制造鞋子，衣服
            Shoes shoes = factory.CreateShoes();
            Clothes cloth = factory.CreateClothes();
            //看看生产的是
            Console.WriteLine("生产：{0},{1}", shoes.Name, cloth.Name);

            Console.WriteLine("冬季工厂生产...");
            //冬季工厂
            Factory factory1 = new WinterFactory();
            //制造鞋子
            Shoes shoes1 = factory1.CreateShoes();
            Clothes cloth1 = factory1.CreateClothes();
            //看看生产的是
            Console.WriteLine("生产：{0},{1}", shoes1.Name, cloth1.Name);
            Console.Read();

        }
    }

 

 结果：
