问在视图中显示视图模型中的数据

EN

The model item passed into the dictionary is of type 
'System.Collections.Generic.List`1[XNet.Repository.Model.RoomType]', 
but this dictionary requires a model item of type 
'System.Collections.Generic.IEnumerable`1[XNet.Repository.Model.EditRoomTypeViewModel]'.

public List<EditRoomTypeViewModel> GetViewRoom(int RoomTypeID)

{
    List<RoomType> roomTypes = (from d in _RoomTypeRepository.All()
                          select d).ToList();

    List<EditRoomTypeViewModel> editRoomTypeViewModel = new List<EditRoomTypeViewModel>();

    foreach (RoomType roomType in roomTypes)
    {
        editRoomTypeViewModel.Add(new EditRoomTypeViewModel
        {
            RoomTypeID = RoomTypeID,
            RoomTypeName = roomType.RoomtypeName,
            RoomTypeDescription = roomType.RoomTypeDescripton,
        });
    }

    return editRoomTypeViewModel;
}

public ActionResult Room()
        {
            ViewBag.hotel = _hotelService.GetByID(2).HotelName;

            List<EditRoomTypeViewModel> editRoomTypeViewModel = _roomViewService.GetViewRoom(_HotelID);
            return View(editRoomTypeViewModel.FirstOrDefault());
        }

 public class EditRoomTypeViewModel
    {
        public int RoomTypeID { get; set; }
        public string RoomTypeName { get; set; }
        public string RoomTypeDescription { get; set; }

    }

}
