How can i check if an entityset of a linq-object is populated or not? Example code below.

My model have two methods, one joins data, and the other does not:

public static Member GetMemberWithSettings(Guid memberId)
{
    using (DataContext db = new DataContext())
    {
        DataLoadOptions dataLoadOptions = new DataLoadOptions();
        dataLoadOptions.LoadWith<Member>(x => x.Settings);
        db.LoadOptions = dataLoadOptions;

        var query = from x in db.Members
                    where x.MemberId == memberId
                    select x;

        return query.FirstOrDefault();

    }
}

public static Member GetMember(Guid memberId)
{
    using (DataContext db = new DataContext())
    {
        var query = from x in db.Members
                    where x.MemberId == memberId
                    select x;

        return query.FirstOrDefault();
    }
}

Then my control have the following code:

Member member1 = Member.GetMemberWithSettings(memberId);
Member member2 = Member.GetMember(memberId);

Debug.WriteLine(member1.Settings.Count);
Debug.WriteLine(member2.Settings.Count);

The last line will generate a "Cannot access a disposed object" exception. I know that i can get rid of that exception just by not disposing the datacontext, but then the last line will generate a new query to the database, and i don't want that.

What i would like is something like:

Debug.WriteLine((member1.Settings.IsPopulated()) ? member1.Settings.Count : -1);
Debug.WriteLine((member2.Settings.IsPopulated()) ? member2.Settings.Count : -1);

Is it possible?
