近期工作比较忙,忙到忘记写博客(自己的借口,主要加班下班后不想动)。
月初的时候,打算每两天写一篇博文,分享自己的一些心得和开发体验,无奈现在只写到第六篇,然而时间已经是20号,岁月不饶人!
总想写点什么,但是有时候文笔可能不咋样,排版也不是很讲究,写的碎碎的。
虽然阅读量、推荐量不高,但是我感觉做事就要持之以恒,保持分享精神!
上一篇写了一些office的操作,包括excel word html pdf,现在想想,确实有点粗糙,不够精炼。
今天准备写一篇关于config文件的基本操作,包括:链接字符串,appSettings操作,运行地址等等。
大家都知道,有时候一些sdk信息账户为了可配置化,除了存库以外,webconfig的配置更能方便简介,且容易维护!
下面贴出我的帮助类(借鉴了cyqdata的帮助类,然后做了一些修改):

OK,各位看官,这一期的文章config操作写到这里喏,感谢大家的支持,您的支持是我的动力!
下一期给大家带来的是常用的Log帮助类,敬请期待!!!
