INI配置文件C#类
在这个漫天都是XML配置文件飞的年代很难在找我们这些还喜欢用INI/INF/CFG配置文件的人了
有时候真觉得让人感伤XML的性能是无法比拟INI配置文件的 但XML的树形结构直观可析 不过其
实INI配置文件同样可以建立为树形结构本身它便是树形结构 有人可能说INI不安全 那么我请问你
XML又安全在哪里了呢 还不是一个鬼样 XML除结构清晰层次分明 但在性能上它与INI比不占优势
推崇它可以 但别把它和INI结构配置文件进行比较 它们本身就是不一样的东西
下面的代码按照.Net的风格编写的一套INI配置文件类 想必大家应该可以轻松上手 函数名你会发
现会有些XmlDocument的命名然而它们的用法本质都一样 Load加载 / Save 保存
