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(duì)配置文件中
appSettings,connectionStrings節(jié)點(diǎn)的操作。關(guān)于配置文件的知識(shí)，我建議大家到周金橋老師的博客，去學(xué)習(xí)一下，我覺(jué)得他講的
較詳細(xì)些，僅僅是一個(gè)建議。如果你對(duì)我寫的代碼有什么想法或者疑問(wèn)，請(qǐng)給我發(fā)郵件或加我QQ（郵件：baiyu311@yahoo.cn
QQ：602316022） 說(shuō)明一下，我現(xiàn)在還是個(gè)學(xué)生，有些技術(shù)上的問(wèn)題未必會(huì)懂，但我堅(jiān)信通過(guò)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(gè)Linux人，開(kāi)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： using System;
