1, new project--web--mvc4web application;

2, enter the name--OK--empty--

3. Add new Project--c# Class Library: BLL (reference DAL, Models), DAL (reference Models), Models

4, UI part is the MVC part (refer to BLL, Models)

5. Dal add Helper folder, SqlHelper class

6. Add a controller to add a folder with the same name as the controller under the view

controllers, views, and routes are three issues that MVC must consider at the same time
