'================= 属性说明 ================
'INI.OpenFile = 文件路径(使用虚拟路径需在外部定义)
'INI.CodeSet = 编码设置,默认为 GB2312
'INI.IsTrue = 检测文件是否正常(存在)
'================ 方法说明 =================
'IsGroup(组名) 检测组是否存在
'IsNode(组名,节点名) 检测节点是否存在
'GetGroup(组名) 读取组信息
'CountGroup() 统计组数量
'ReadNode(组名,节点名) 读取节点数据
'WriteGroup(组名) 创建组
'WriteNode(组,节点,节点数据) 插入/更新节点数据
'DeleteGroup(组名) 删除组
'DeleteNode(组名,节点名) 删除节点
'Save() 保存文件
'Close() 清除内部数据(释放)
