精选优质文档-倾情为你奉上实验一：工厂模式的应用实验目的1) 掌握工厂模式（Factory）的特点2) 分析具体问题，使用工厂模式进行设计。实验内容和要求有一个OEM制造商代理做HP笔记本电脑(Laptop)，后来该制造商得到了更多的品牌笔记本电脑的订单Acer，Lenovo，Dell，该OEM商发现，如果一次同时做很多个牌子的本本，有些不利于管理。利用工厂模式改善设计实验UML图实验源代码using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Factory interface ComputerFactory Computer CreateComputer(); abstract class Computer protected string computer; public abstract string newcomputer(); class Hp : Computer public override string newcomputer() return "This a new Hp computer" class Dell : Computer public override string newcomputer() return "This a new Dell computer" class Lenovo : Computer public override string newcomputer() return "This a new Lenovo computer" class Acer : Computer public override string newcomputer() return "This a new Acer computer" class HpFactory : ComputerFactory public Computer CreateComputer() return new Hp(); class DellFactory : ComputerFactory public Computer CreateComputer() return new Dell(); class LenovoFactory : ComputerFactory public Computer CreateComputer() return new Lenovo(); class AcerFactory : ComputerFactory public Computer CreateComputer() return new Acer(); class Program static void Main(string args) ComputerFactory HpComputer = new HpFactory(); ComputerFactory DellComputer = new DellFactory(); ComputerFactory LenovoComputer = new LenovoFactory(); ComputerFactory AcerComputer = new AcerFactory(); Computer Hp = HpComputer.CreateComputer(); Computer Dell = DellComputer.CreateComputer(); Computer Lenovo = LenovoComputer.CreateComputer(); Computer Acer = AcerComputer.CreateComputer(); Console.WriteLine("They are new computers："); string result1 = Hp.newcomputer(); string result2 = Dell.newcomputer(); string result3 = Lenovo.newcomputer(); string result4= Acer.newcomputer(); Console.WriteLine( result1); Console.WriteLine( result2); Console.WriteLine( result3); Console.WriteLine( result4); Console.ReadLine(); 实验结果截屏实验小结 通过本次实验，加深了对工厂模式的理解:在工厂方法模式中，父类负责定义创建对象的公共接口，而子类则负责生成具体的对象，这样做的目的是将类的实例化操作延迟到子类中完成，即由子类来决定究竟应该实例化(创建) 哪一个类。 专心-专注-专业
