Connect [Authorize] with custom database

Question

How do I order the [Authorize] attribute to connect to my own Roles database to check for specifics roles in there?

What I know:

• I have to create a class that inherits from AuthorizeAttribute.

What I don't know:

• What to write inside my custom class in the way that [CustomAuthorize(Roles: "Administrator")] checks if the current user has that role.

Please, I really need help with this.

Answer 1

Override the AuthorizeCore() method and return true or false.

Answer 2

Simply create a custom RoleProvider to work with the ASP.NET Identification.
