本文实例讲述了C#设计模式之Builder生成器模式解决带老婆配置电脑问题。分享给大家供大家参考,具体如下:
一、理论定义
生成器模式 又叫:建造者模式,它 可以 把一个 复杂的对象,分步骤创建。
二、应用举例
需求描述:话说发工资了,打算去岗顶百脑汇 给老婆配置一台电脑。
OK,坐着BRT,就出发了。
到岗顶,一美女扑面而来,面带微笑:先生,请问看中那个品牌,过来看一下嘛!
人家都开口了,盛情难却,就看下吧。

21.运行结果
22.总结
本来想把每个电脑配件再细化,发现工程很大,电脑 产品的属性很多,所以只列出2个字段。
附件里面包括了程序源码。也包括其他项目的测试,有控制台,有web。
