這篇文章主要介紹了C#設計模式之Facade面板模式解決天河城購物問題,簡單描述了面板模式的定義並結合具體執行個體分析了面板模式解決購物問題的相關步驟與操作技巧,需要的朋友可以參考下
本文執行個體講述了C#設計模式之Facade面板模式解決天河城購物問題。分享給大家供大家參考,具體如下:
一、理論定義
面板模式 把 分散的子系統,集合成一個系統,提供一站式服務。
二、應用舉例
需求描述: 聶小倩 和 寧采臣是一對小富則安 的聊齋夫妻。住在比較偏遠的小鄉村。
今天,兩人初次來到大城市廣州,聽說天河城提供一站式服務,不像小城市那樣,買個東西 得 東奔西跑。
在一個地方,就可以買到 自己想要的衣服,電腦,鞋子,Iphone,還可以看大片,
吃冰淇淋,吃真功夫,買化妝品,珠寶首飾。天河城,果然是一寶地啊。
Ok,邊走邊看。
三、具體編碼
1.阿迪達斯
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 阿迪達斯 /// </summary> public class Adidas { public void Serivce(string something) { Console.WriteLine("在阿迪達斯購買了: "+something); } }}

4.哈根達斯
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 哈根達斯 /// </summary> public class HaagenDaz { public void Serivce(string something) { Console.WriteLine("在哈根達斯 買了: " + something); } }}
5.真功夫
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 真功夫 /// </summary> public class KungFu { public void Serivce(string something) { Console.WriteLine("在真功夫 吃了: " + something); } }}
6.六福珠寶
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 六福珠寶 /// </summary> public class LukFook { public void Serivce(string something) { Console.WriteLine("在六福珠寶 買了: " + something); } }}
7.耐克
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 耐克 /// </summary> public class NIKE { public void Serivce(string something) { Console.WriteLine("在耐克店 買了: " + something); } }}
8.ONLY
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// ONLY時裝 /// </summary> public class ONLY { public void Serivce(string something) { Console.WriteLine("在ONLY時裝 買了: " + something); } }}
9.蘇寧電器
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 蘇寧電器 /// </summary> public class Suning { public void Serivce(string something) { Console.WriteLine("在蘇寧電器 買了: " + something); } }}
10.Veromoda國際時裝品牌
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// Veromoda國際時裝品牌 /// </summary> public class Veromoda { public void Serivce(string something) { Console.WriteLine(something); } }}
11.消費者
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Com.Design.Gof.Facade{ /// <summary> /// 消費店子 /// </summary> public enum ShopOption { Adidas = 1, DKNY = 2, GoMe = 3, NIKE = 4, Suning = 5, Veromoda = 6, FeiYangMovie = 7, HaagenDaz = 8, LukFook = 9, KungFu = 10 } /// <summary> /// 消費單 /// </summary> public class Bill { /// <summary> /// 要去的消費店 /// </summary> public ShopOption Item { get; set; } /// <summary> /// 去這個店要買啥 /// </summary> public string Something { get; set; } } public class Consumer { /// <summary> /// 消費單 /// </summary> public IList<Bill> Items { get; set; } /// <summary> /// 姓名 /// </summary> public string Name { get; set; } }}
12.天河城---一站式服務
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Reflection;namespace Com.Design.Gof.Facade{ /// <summary> /// 天河城 /// </summary> public class TeeMall { private static readonly Assembly assembly = Assembly.LoadFile(AppDomain.CurrentDomain.BaseDirectory + @"\Com.Design.Gof.dll"); /// <summary> /// 一站式服務 /// </summary> /// <param name="consumer"></param> public void OfferService(Consumer consumer) { Console.WriteLine("我是: " + consumer.Name+",不差錢,今天來天河城玩: "); Console.WriteLine("----------------------------------------------"); foreach (Bill item in consumer.Items) { object obj= assembly.CreateInstance("Com.Design.Gof.Facade." + item.Item); MethodInfo info = obj.GetType().GetMethod("Serivce"); info.Invoke(obj, new object[] { item.Something }); } Console.WriteLine(); } }}
13.主函數調用
using System;using System.Collections.Generic;using System.Linq;using System.Text;using Com.Design.Gof.Facade;namespace Com.Design.Gof.Test{ class Program { static void Main(string[] args) { //天河城購物中心 TeeMall TeeMall = new TeeMall(); //消費者 1 Consumer consumer = new Consumer { Name="聶小倩", //消費單 Items = new List<Bill> { new Bill{ Item=ShopOption.Adidas, Something="運動服"}, new Bill{ Item=ShopOption.GoMe, Something="蘋果IPhone智能手機"}, new Bill{ Item=ShopOption.FeiYangMovie, Something="<冰河世紀 4>"}, new Bill{ Item=ShopOption.KungFu, Something="香菇燉雞"}, new Bill{ Item=ShopOption.LukFook, Something="金項鏈"}, } }; TeeMall.OfferService(consumer); //消費者 2 consumer = new Consumer { Name = "寧采臣", //消費單 Items = new List<Bill> { new Bill{ Item=ShopOption.FeiYangMovie, Something="《太空一號》"}, new Bill{ Item=ShopOption.Veromoda, Something="然後去了Veromoda時裝,買了一套服裝"}, new Bill{ Item=ShopOption.HaagenDaz, Something="買了一雪糕"}, new Bill{ Item=ShopOption.Suning, Something="在蘇寧看買平板電腦"}, } }; TeeMall.OfferService(consumer); Console.ReadKey(); } }}
14.運行結果
15.總結
天河城 TeeMall 理論上應該包括 所有 商場的引用,
這裡用反射 避免了這一動作。
