    /// DBC为数据库操作对象接口,常用到的基本上都封装好了，没有DataReader,用DataTable代替，当然你也完全可以扩展。
    /// IDC为数据库相关方法的接口，可以进行扩展。比如现在只支持Sql和Access数据库，你完全可以再增加MySqlDbCom.cs以实现MySql的支持。
    /// RC为配置信息对象。
    /// 
    /// 
    /// 另：
    /// 其实这个dll除了整合登陆，还可以根据需要扩展很多功能的，关键看大家的需求和创意了。
    /// 当然目前还会有很多不足的地方，希望大家一起帮助完善吧。
    /// 只是别忘了与大家一起分享，共同进步：）
