Is it Roles or Visitor Groups that you mean?
For users in Roles (admins, editors etc) try something like this:
private readonly Injected<UIRoleProvider> _roleProvider;
Then use the method "GetUsersInRole":
var groupName = "WebEditors"; var userNames = _roleProvider.Service.GetUsersInRole(groupName);
I want to get the List of all users inside a Group in my code, is there any Repository that can provide me with that information.
