C＃：返回符合条件的任何项目

I have a method like this:

我有这样的方法:

    public ActionResult ShowAvailableSpots(int Id, DateTime ArrivalDate, DateTime LeaveDate)
    {
        var query2 = db.Spots
            .Where(c => db.Reservations.Any(r =>
                           DbFunctions.TruncateTime(ArrivalDate) <= DbFunctions.TruncateTime(r.ArrivalDate) && DbFunctions.TruncateTime(LeaveDate) <= DbFunctions.TruncateTime(r.ArrivalDate)
                        || DbFunctions.TruncateTime(ArrivalDate) >= DbFunctions.TruncateTime(r.LeaveDate)
            )).ToList();

        ViewBag.StartingDate = ArrivalDate;
        ViewBag.EndingDate = LeaveDate;
        ViewBag.AvailableSpots = query2;

        ViewBag.CampingSpotId = new SelectList(query2, "CampingSpotId", "SpotName");

        return View();
    }
