How do i get all users from a specific role?

var users = Membership.GetAllUsers();

gets all users in all roles.

it returns a list of MembershipUser, but there is no role property.

Thanks

You need to use the Roles class defined in System.Web.Security. It has a Roles.GetUsersInRole method.

Here is the documentation.

If you want to map the returned username to a MembershipUser you can use Membership.GetUser(string username) method on each of the returned values.

Roles are handled by the role provider not the membership provider (for separation of authorisation from authentication).

So

string[] RoleProvider.GetUsersInRole(roleName)

(msdn).
