                                       requestReservation.reservationId = "000" + (number + 1).ToString();
                                       requestReservation.result = ReservationType.ReservationResultType.Success;

                                       {
                                           foreach (Room rm in h.RoomList)
                                           {
                                               if (requestReservation.hotelId == h.HotelId && requestReservation.roomType == rm.RoomType)
                                               {
                                                   requestReservation.cost = (requestReservation.numDays * rm.Rate);
                                               }

                                           }
                                       }
                                   } // end of if num == counts
                                   else {
                                       requestReservation.reservationId = null;
                                       requestReservation.result = ReservationType.ReservationResultType.RoomNotAvailable;
                                       count = 0;
                                   }

                               } //end of if


                           }//end of forloop

                       }//end of if statement (Roomtypes)

                   }//end of If statement( inventory.hotelID)

               } // end of foreach inventory
               number++;
           }// end of Foreach

           serial = new XmlSerializer(RequestReservation.GetType());
           sw = new StreamWriter(ReservationFilename);
           serial.Serialize(sw, RequestReservation);
           sw.Close();


       }// End of ReserveRoom Method

What I have tried:

1)after the condition was true, i did forloop to go through each variables where datelist[i] == inventory.date and deduct 1 from it.

2) without the for loop, after condition was true, deduct 1 , but did not change at all.

I wrote a function recently that starts incrementing a value then when the peak is reached it starts decrementing, i used it to animate rgb colors on page

C#

var current;
const min = 0;
const max = 255;
var b = true;

    if (b == true) {
        current += 1;
        if (current >= max) {
            b = false;
        }
    }
    else {
        current = current - 1;
        if (current <= min) {
            b = true;
    }

There is no real question here, but I guess your code don't work as expected.
Without your data, we can't devise what is going on.
The only possibility is to use the debugger and check the variables values as the code is executing.

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.
Debugger - Wikipedia, the free encyclopedia[^]
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
When the code don't do what is expected, you are close to a bug.
