How to do handle login-logoff

问题

I am using the new user authentication system Asp.Net Identity in my project. I have a situation where I have to store 3 types of users in database i.e.:

• Student
• Teacher
• Admin

Now all these 3 have there separate table contains different information about each one of them. I want Asp.Net Identity to handle their login, logoff and password maintance for each type of user.

Can anyone please guide me with the overview of how can I handle this situation?

回答1:

You need an inheritance structure like this:

public abstract class User {}
public class Student : User {}
public class Teacher : User {}
public class Admin : User {}

where the User base class holds all necessary info for authentication. This way, you can handle all types of Users in a unified way.

Regarding the database, there are various strategies how such polymorphism can be handled (e.g. Table per Concrete Type).

Here's what I just thought :

First of all, in your database make a table named "Roles", which will contains all your roles, as you mentioned in your post ( Student, Teacher, Admin and so on )

Then put a foreign key in your tables ( RoleId )

Make your custom membership provider

I think this should work
