INI配置文件C#類

ny8p 9年前發布 | 1K 次閱讀 C#

在這個漫天都是XML配置文件飛的年代很難在找我們這些還喜歡用INI/INF/CFG配置文件的人了

有時候真覺得讓人感傷XML的性能是無法比擬INI配置文件的但XML的樹形結構直觀可析不過其

實INI配置文件同樣可以建立為樹形結構本身它便是樹形結構有人可能說INI不安全那么我請問你

XML又安全在哪里了呢還不是一個鬼樣 XML除結構清晰層次分明但在性能上它與INI比不占優勢

推崇它可以但別把它和INI結構配置文件進行比較它們本身就是不一樣的東西

下面的代碼按照.Net的風格編寫的一套INI配置文件類想必大家應該可以輕松上手函數名你會發

現會有些XmlDocument的命名然而它們的用法本質都一樣 Load加載 / Save 保存
