抽象工程模式实例

---恢复内容开始---

用户需求：

用程序模拟以下产品线并代码实现

设计思路：

1.UML图

2.采用抽象工厂模式，将具体产品从客户代码中分离，容易改变产品的系列，能将一个系列的产品族统一到一起创建。

具体代码实现：

1.抽象工厂模式实现类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace 设计模式作业
{
    public class MyClass
    {
        public interface Burger {
             string getBurger();
        }
        public class KFCBurger :Burger{
            public string getBurger() {

                return "我是KFC的巨无霸汉堡";
                
            }
        }
        public class MCBurger : Burger {
            public string getBurger()
            {
                
                return "我是McDonalds的巨无霸汉堡";
            }
        }
        public interface Chicken {
             string getChicken();
        }
        public class KFCChicken : Chicken {
            public string getChicken()
            {
               
                return "我是来自KFC的炸鸡";

            }
        }
        public class MCChicken : Chicken {
            public string getChicken()
            {
               
                return "我是来自McDonalds的炸鸡";

            }
        }
        public interface Drink {
            string getDrink();
        }
        public class KFCDrink : Drink {
            public string getDrink()
            {
              
                return "我是来自KFC的咖啡";

            }
        }
        public class MCDrink : Drink {
            public string getDrink()
            {
                return "我是来自McDonalds的橙汁";

           }
        }
        public interface AbstractFactory {
             Burger createBurger();
             Chicken createChicken();
             Drink createDrink();
        }
        public class KFCFactory : AbstractFactory {
            public Burger createBurger() {
                return new KFCBurger();
            }
            public Chicken createChicken() {
                return new KFCChicken();
            }
            public Drink createDrink() {
                return new KFCDrink();
            }
            
        }
        public class MCFactory : AbstractFactory
        {
            public Burger createBurger()
            {
                return new MCBurger();
            }
            public Chicken createChicken()
            {
                return new MCChicken();
            }
            public Drink createDrink()
            {
                return new MCDrink();
            }

        }

       
    }
}

2.KFC生产线实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace 设计模式作业
{
    public partial class WebForm1 : System.Web.UI.Page
    {

        MyClass.AbstractFactory af = new MyClass.KFCFactory();
        
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            MyClass.Burger kfcburger = af.createBurger();
            Label1.Text = kfcburger.getBurger();
            

        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            MyClass.Chicken kfcckicken = af.createChicken();
            Label1.Text = kfcckicken.getChicken();

        }

        protected void Button3_Click(object sender, EventArgs e)
        {
            MyClass.Drink kfcdrink = af.createDrink();
            Label1.Text = kfcdrink.getDrink();
        }
    }
}

3.McDonalds生产线实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace 设计模式作业
{
    public partial class WebForm2 : System.Web.UI.Page
    {
        MyClass.AbstractFactory af = new MyClass.MCFactory();
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            MyClass.Burger mcburger = af.createBurger();
            Label1.Text = mcburger.getBurger();

        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            MyClass.Chicken mcchicken = af.createChicken();
            Label1.Text = mcchicken.getChicken();

        }

        protected void Button3_Click(object sender, EventArgs e)
        {
            MyClass.Drink mcdrink = af.createDrink();
            Label1.Text = mcdrink.getDrink();

        }
    }
}
