本文实例讲述了c#设计模式之facade外观模式解决天河城购物问题。分享给大家供大家参考,具体如下:
一、理论定义
外观模式 把 分散的子系统,集合成一个系统,提供一站式服务。
二、应用举例
需求描述: 聂小倩 和 宁采臣是一对小富则安 的聊斋夫妻。住在比较偏远的小乡村。
今天,两人初次来到大城市广州,听说天河城提供一站式服务,不像小城市那样,买个东西 得 东奔西跑。
在一个地方,就可以买到 自己想要的衣服,电脑,鞋子,iphone,还可以看大片,
吃冰淇淋,吃真功夫,买化妆品,珠宝首饰。天河城,果然是一宝地啊。
ok,边走边看。

14.运行结果
15.总结
天河城 teemall 理论上应该包括 所有 商场的引用,
这里用反射 避免了这一动作。
