I think you can do that by using the Membership Api.

Would be something like that i think:

List<MembershipUser> onlineUsers =newList<MembershipUser>();

foreach(MembershipUser user in Membership.GetAllUsers()){ if(user.IsOnline){ onlineUsers.Add(user);}}

With the ProviderUserKey you can than create the Umbraco Member with: var member = new Member(id);

Hope that is want you've been looking for.

OK thanks for your reply; I tried the following and it appears to list all of my previous logins and not just my current session.

    List<MembershipUser> onlineUsers = new List<MembershipUser>();

    foreach (MembershipUser ServiceAdvisorUser in Membership.GetAllUsers())

    {

        if (ServiceAdvisorUser.IsOnline)

        {

            onlineUsers.Add(ServiceAdvisorUser);

        }

    }    

    @*loop through and create umbraco members*@

    List<Member> UmbracoLoggedInUsers = new List<Member>();

    foreach(MembershipUser loggedInUser in onlineUsers)

    {

        Member member = new Member((int)loggedInUser.ProviderUserKey); // Umbraco Member class        

        UmbracoLoggedInUsers.Add(member);

    }

In addition I did the same approach using 

 @foreach(Member loggedInMemberToDisplay in umbraco.cms.businesslogic.member.Member.CachedMembers())

However this is returning zero

I will try it again. But it seems that it should in general work.

One thing i discovered is that Membershit.GetAllUsers() also returns the users and not only the members.

So maybe using Member.GetAllAsList().Where(x => x.MemberType == yourmembertype); would be the better choice.

Ok after a few hours research and testing here are my results:

The MembershipUser.IsOnline just checks if the LastActivityDate is greater than current time - OnlyTimeWindow.

The LastActivityDate is set when using CreateUser, UpdateUser and ValidateUser. Also it can be set by using GetUser(object,bool) where the bool value indicates if the date should be updated.

After I looked at the umbraco code i saw no point where the boolvalue is actually used, so the LastActivityDate never gets updated.

Also I tried so set the value manually on login/logout but after 30 minutes the users still was "online".

So as a result i think the IsOnline property just always returns true.

Maybe that should be added to the issue tracker.

If someone else has a working method I would be glad to here it.

Thanks for your post David - I will keep digging and post if I come up with a solution.
