ASP. net mvc + LINQ develop a book sales site (5): Create a logic layer interface

Let's familiarize ourselves with the process by using the Directory management on the administrator interface.

1. we want to view all directories in the same way as category/list. category/New is used to add directories and category/edit/{ID} is used to modify directories, category/delete/{ID} to delete a directory.

URL format	Action	URL example
/Category/List	Browse all directories	/Category/List
/Category/edit/ID	Edit Selected directory	/Category/edit/1
/Category/delete/ID	Delete restricted directories	/Category/delete/2
/Category/Add	Add directory	/Category/Add

 

2. If you want to access the corresponding function based on the above address, first we need a category controller. In the Controller directory, create a new categorycontroller.

3. Define the following behavior in categorycontroller (Note: All public methods are a controller action, which is a change in preview2)
