c# ini读写操作

ini读写代码详解实例，有很详细注释，保证满意； 预览截取一部分代码: ///    /// 读取INI文件中指定INI文件中的所有节点名称(Section)   ///    /// Ini文件   /// 所有节点,没有内容返回string[0]   public static string[] INIGetAllSectionNames(string iniFile) { uint MAX_BUFFER = 32767; //默认为32767   string[] sections = new string[0]; //返回值   //申请内存   IntPtr pReturnedString = Marshal.
