本文實(shí)例講述了C#設(shè)計(jì)模式之Builder生成器模式解決帶老婆配置電腦問(wèn)題。分享給大家供大家參考，具體如下：
一、理論定義
生成器模式 又叫：建造者模式，它 可以 把一個(gè) 復(fù)雜的對(duì)象，分步驟創(chuàng)建。
二、應(yīng)用舉例
需求描述：話(huà)說(shuō)發(fā)工資了，打算去崗頂百腦匯 給老婆配置一臺(tái)電腦。
OK，坐著B(niǎo)RT，就出發(fā)了。
到崗頂，一美女撲面而來(lái)，面帶微笑：先生，請(qǐng)問(wèn)看中那個(gè)品牌，過(guò)來(lái)看一下嘛！
人家都開(kāi)口了，盛情難卻，就看下吧。
