Elevator program code challenge, revised:

Can someone please critique my Elevator problem - I wanted to use OOP principles and coding standards. Also, does logic make sense?

```
internal enum Status
{
    GoingUp,
    GoingDown,
    Stopped
}

internal class Elevator
{
    private readonly SortedList<int, bool> _sorted = new SortedList<int, bool>();
    public readonly int TopFloor;

    public Elevator(int topFloor)
    {
        TopFloor = topFloor;
    }

    public int CurrentFloor { get; set; } = 1;
    public Status Status { get; set; } = Status.Stopped;

    public void AddRequest(int floor)
    {
        if (!_sorted.ContainsKey(floor))
            _sorted.Add(floor, false);

        switch (Status) {
            case Status.GoingDown:
                MoveDown();
                break;

            case Status.Stopped:
                if (CurrentFloor < floor)
                    MoveUp();
                else
                    MoveDown();
                break;

            case Status.GoingUp:
                MoveUp();
                break;

            default:
                break;
        }
    }

    public void MoveUp()
    {
        var max = _sorted.OrderByDescending(x => x.Key).First();
        for (var i = CurrentFloor; i <= max.Key; i++) // Go to top most requested floor
            if (_sorted.ContainsKey(i))
                Stop(i);
            else
                continue;

        Status = Status.Stopped;
    }

    public void MoveDown()
    {
        var min = _sorted.OrderBy(x => x.Key).First();
        for (var i = CurrentFloor; i >= min.Key; i--)
            if (_sorted.ContainsKey(i))
                Stop(i);
            else
                continue;

        Status = Status.Stopped;
    }

    public void Stop(int floor)
    {
        _sorted.Remove(floor);
        CurrentFloor = floor;
        Console.WriteLine("Stopped at: {0}", CurrentFloor);
    }
}

internal class Manager
{
    private readonly Elevator _elevator = new Elevator(10);

    public void ButtonPressed(int floor)
    {
         // testing...
        _elevator.AddRequest(10);
        _elevator.AddRequest(10);
        _elevator.AddRequest(5);
        _elevator.AddRequest(2);
        _elevator.AddRequest(9);
        _elevator.AddRequest(6);
    }
}
