下面的代碼是我看完周金橋老師的ASP.NET夜話，以及上網(wǎng)查了一些東西后，自己寫的關(guān)于對配置文件中appSettings,connectionStrings節(jié)點的操作。關(guān)于配置文件的知識，我建議大家到周金橋老師的博客，去學(xué)習(xí)一下，我覺得他講的較詳細(xì)些，僅僅是一個建議。如果你對我寫的代碼有什么想法或者疑問，請給我發(fā)郵件或加我QQ（郵件：baiyu311@yahoo.cnQQ：602316022）
說明一下，我現(xiàn)在還是個學(xué)生，有些技術(shù)上的問題未必會懂，但我堅信通過我們的努力是可以客服它的。還有我最近在學(xué)習(xí)Linux，很想做一個Linux人，開源嘛，如果你有興趣也可以聯(lián)系我。期待每位上進(jìn)的朋友，嘿嘿。。。。下面是我的代碼：
