這篇文章主要介紹了C#設計模式之Builder生成器模式解決帶老婆配置電腦問題,簡單介紹了生成器模式的概念、功能並結合具體實例形式分析了C#生成器模式解決配電腦問題的步驟與相關操作技巧,需要的朋友可以參考下
本文實例講述了C#設計模式之Builder生成器模式解決帶老婆配置電腦問題。分享給大家供大家參考,如下:
一、理論定義
生成器模式又叫:建造者模式,它 可以把一個複雜的對象,分步驟創建。
二、應用範例
需求描述:話說發薪水了,打算去崗頂百腦匯 為老婆設定一台電腦。
OK,坐著BRT,就出發了。
到崗頂,一美女撲面而來,面帶微笑:先生,請問看中那個品牌,過來看一下嘛!
人家都開口了,盛情難卻,就看下吧。
