Asp.Net 常用工具類---Config操作（7）

近期工作比較忙，忙到忘記寫博客（自己的借口，主要加班下班後不想動）。

月初的時候，打算每兩天寫一篇博文，分享自己的一些心得和開發體驗，無奈現在只寫到第六篇，然而時間已經是20號，歲月不饒人！

總想寫點什麼，但是有時候文筆可能不咋樣，排版也不是很講究，寫的碎碎的。

雖然閱讀量、推薦量不高，但是我感覺做事就要持之以恆，保持分享精神！

上一篇寫了一些office的操作，包括excel word html pdf，現在想想，確實有點粗糙，不夠精鍊。

今天準備寫一篇關於config文件的基本操作，包括：鏈接字元串，appSettings操作，運行地址等等。

大家都知道，有時候一些sdk信息賬戶為了可配置化，除了存庫以外，webconfig的配置更能方便簡介，且容易維護！

下面貼出我的幫助類（借鑒了cyqdata的幫助類，然後做了一些修改）：
