Checking if a user is in a role in asp.net mvc Identity

Question

I\'m having an issue seeding my database with users and roles.

The User and the Role are both created (I can see them in the database after the error is thrown).

Answer 1

I found out the solution, in case anyone else is having this problem.

The "IsInRole" is expecting a User.Id - not a UserName string - so I changed to:

            if (!userManager.IsInRole(user.Id, "Admin"))
            {
                userManager.AddToRole(user.Id, "Admin");
            }

So the working code becomes:

    ApplicationDbContext userscontext = new ApplicationDbContext();
    var userStore = new UserStore(userscontext);
    var userManager = new UserManager(userStore);

    var roleStore = new RoleStore(userscontext);
    var roleManager = new RoleManager(roleStore);

    // Create Role
    if (!roleManager.RoleExists("Admin"))
    { 
        roleManager.Create(new IdentityRole("Admin"));
    }

    if(!userscontext.Users.Any(x=> x.UserName=="marktest"))
    {
        // Create User
        var user = new ApplicationUser { UserName = "marktest", Email = "marktest@gmail.com" };
        userManager.Create(user, "Pa$$W0rD!");

        // Add User To Role
        if (!userManager.IsInRole(user.Id, "Admin"))
            {
                userManager.AddToRole(user.Id, "Admin");
            }


    }

I hope that helps,
