整个项目主要采用三层架构，面向接口的编程方式。界面层：User Interface  CinDou.Web主要放我们的Web页面，CinDou.Route主要放置MVC中Controller，这里我采用把Controller分离出来。个人考虑的原因是：项目比较清晰，职责比较单一。逻辑层：Business Logic Layer  CinDou.BFactory 是逻辑工厂层，用于创建逻辑层的接口，便于界面层调用。CinDou.IBLL 逻辑接口层CinDou.BLL 逻辑业务层 主要负责逻辑层中的业务。CinDou.Model 逻辑业务类数据库层：Data Accss LayerCinDou.DFacoty:数据工厂层，用于创建数据库层的接口，从而让逻辑层调用CinDou.IDAL : 数据库接口层CinDou.DAL : 数据库持久层CinDou.EFramework: Entity Framework层工具层：ToolKitCinDou.Tools 常用的工具类方法层Component :控件层

  这是一个小的日志提示程序，一运行，就会出现首页，按alt f4隐藏首页，该图标会在显示在右下角托盘上。4当到一定的时间，就会自动运行别外一个页面，打开你的主页，主页上写上你的要做的事情就OK，我设定的是17:55:18分，大家可以根据需要，我加几个窗口，来提示某时做什么。 可以通过这个程序学会托盘程序的编写方法。文件中有源文件和安装文件，安装前请先安装.netFramework运行环境。vs2008制作
