How to assign a Role to a user in MVC5?

问题

In MVC4 I was using the code

Roles.AddUserToRole(User.Identity.Name, "Approved");

Is there any other way of doing the same(adding user to role "Approved") in MVC5 Identity Model?

EDIT: I meant to ask is this the right way of adding a user to a role? Because in a lot of examples they do not use this code.

回答1:

You can call AddToRole or AddToRoleAsync as an instance method on any object of type UserManager<TUser> to achieve it in MVC 5, like below:

var _context = new ApplicationDbContext();
var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(_context));
UserManager.AddToRole("UserName", "UserRole");
