如果/ else条件在嵌套的foreach循环中

Question

我试图在嵌套的foreach循环中使用if语句来检查特定条件，但是有一个点，其中列表中的一个对象与第一个条件不匹配。我遇到的问题是如果我把第一个条件放入其他条件，它会使列表中的所有对象都变得虚假，即使每个对象都有一个匹配，除了最后一个。

public void ReserveRoom(List<ReservationType> reservation)
{
         List<ReservationType> RequestReservation = new List<ReservationType>();

        RequestReservation = reservation;   //List that contains the test cases.

        string reservationid = "0001";
        int number = int.Parse(reservationid);
         int count = 0;
    foreach (ReservationType requestReservation in RequestReservation)
    {
        List<String> DateList = CreateDateList(requestReservation.StartDate, requestReservation.numDays);

        foreach (Inventory inventory in RoomInventory)
        {
            if (requestReservation.hotelId == inventory.HotelId)
            {
                if (requestReservation.roomType == inventory.RoomType)
                {
                    for (int i = 0; i < DateList.Count; i++)
                    {
                        if (DateList[i] == inventory.Date  && inventory.Quantity > 0)
                        {
                            count++;
                            //Console.Write(requestReservation.customerId + ": " + inventory.Date + ": " + count + Environment.NewLine);
                        }
                    }

                    if (requestReservation.numDays == count)
                    {
                        requestReservation.result = ReservationType.ReservationResultType.Success;
                        count = 0;
                    }

                    foreach (String dt in DateList)
                    {
                        if (dt.Equals( inventory.Date))                            
                            inventory.Quantity--;                            
                    }

                    foreach (Hotels h in LHotels)
                    {
                        foreach (Room rm in h.RoomList)
                        {
                             if (requestReservation.hotelId == h.HotelId && requestReservation.roomType == rm.RoomType)                                 
                                 requestReservation.cost = (requestReservation.numDays * rm.Rate);                                 
                        }
                    }                          
                }
            }
            else
            {
              requestReservation.result = ReservationType.ReservationResultType.UnknownHotelId;
            }

        }
        number++;
    }
}

我试图实现的输出：
