Find all User that are NOT in a specifv Role using: Roles.GetUsersInRole or different

Question

I need populate an array with a list of Users that ARE NOT PRESENT in a specific Role and COUNT the result.

At the moment I use this code, but I am not able to get the Users outside "CMS-ADMINISTRATOR " role.

Any idea how to do it and better write the Count section?

       string[] usersInRole;
       usersInRole = Roles.GetUsersInRole("CMS-ADMINISTRATOR");
       int c = usersInRole.Count();

Answer 1

Not sure about getting users outside the "CMS-ADMINISTRATOR" role, but at least you can write the original code better like this:

 int count = Roles.GetUsersInRole("CMS-ADMINISTRATOR").Count();

Answer 2

If you just need the number of users not in the role, you can subtract the number of users in the role from the total number of users:

int count = Membership.GetAllUsers.Count - Roles.GetUsersInRole("CMS-ADMINISTRATOR").Count();

Answer 3

Maybe this:

var users=Membership.GetAllUsers().Cast<MembershipUser>()
           .Count(t=>!Roles.IsUserInRole(t.UserName,"CMS-ADMINISTRATOR"));

Or use what Andy Mikula suggests which is simpler if you just need the count.

Answer 4

Please try,

            var usernames = Roles.GetUsersInRole("Administrator");
            var adminUsers = db.UserProfiles
                 .Where(x => !usernames.Contains(x.UserName)).ToList();

adminusers.count

you can also return it to the view

return View(adminUsers);
