私は最近、私が理解しようとしている小さな問題があることを除いて、私が取り組んできた小さなプロジェクトを終了しました。
このプロジェクトは、SOAP クライアントを使用する C# Web サービスを、要求クラスと応答クラスの両方と共に利用します。このプロジェクトは、入力されたデータを保存するように設計されています。それが行うことは、映画館の列のある座席を予約し、その座席を予約し、その座席を再度選択して、その列の別の空席を (フォーム内で) 見つけようとすると、両方が「0」と表示されることです。 "。ただし、別の行の別の座席を予約すると、そのデータはキャッシュに正常に保存されますが、コードの「else if」ステートメント内に他の座席と行は表示されません。
Webservice の Webmethod は次のとおりです。
public string Name { get; set; } //gets and sets the Name from the ReserveSeatResponse
public int Row { get; set; } //gets and sets the Row from the ReserveSeatResponse
public int Seat { get; set; } //gets and sets the Seat from the ReserveSeatResponse
private const int maxRows = 13; //sets the max amount of Rows in the Array tried setting the rows to 12, but since the array starts at 0, I had to set the Rows to 13)
private const int maxSeats = 17; //sets the max amount of Seats in the Array (tried setting the seats at 16, but since the array starts at 0, I had to set it to 17)
private bool[,]reservedSeats = new bool[13, 17]; //same description above, but this sets a boolean in the reserved seats, to check if its taken or no)
private bool[,]reservedRows = new bool[13, 17]; //same description for the max row/seats.
[WebMethod]
public GetSeatResponse Booking (GetSeatRequest req)
{
GetSeatResponse resp = new GetSeatResponse();
// resp.Seat = req.SeatNumber;
// resp.Row = req.RowNumber;
object abc = HttpContext.Current.Cache["CinemaReservation"];
//if the cache does not exist
if (abc == null)
{
//creates a blank multidimensional array
reservedSeats = new bool[maxRows,maxSeats];
}
//if the cache exists
else
{
//using the cache object as an array
try
{
reservedSeats = (bool[,])abc;
}
catch
{
}
}
//if the seat is vacant
if (reservedSeats[req.RowNumber, req.SeatNumber] != true)
{
resp.Name = req.Name;
resp.Seat = req.SeatNumber;
resp.Row = req.RowNumber;
reservedSeats[req.RowNumber, req.SeatNumber] = true;
HttpContext.Current.Cache["CinemaReservation"] = reservedSeats;
return resp;
}
//if the seat is taken
else if (reservedSeats[req.RowNumber, req.SeatNumber] != true)
{
bool breakTest = false;
string Name = req.Name;
int row = req.RowNumber;
int seat = req.SeatNumber;
for (int i = row; i < reservedSeats.GetLength(0); i++)
{
for (int j = seat; j < reservedSeats.GetLength(1); j++)
{
if (reservedSeats[i, j] !=true )
{
resp.Name = Name;
resp.Row = i+1;
resp.Seat = j+1;
reservedSeats[i, j] = true;
breakTest = true;
break;
}
}
seat = 0;
if (breakTest == true)
{
break;
}
}
//getNextSeat(req, resp, reservedSeats);
HttpContext.Current.Cache["CinemaReservation"] = reservedSeats;
}
return resp;
そして、これがWebサービスから呼び出すメソッドで私が行き詰まっている部分です
if (resp.erroresp != true)
{
if ((resp.Row > 0) && (resp.Seat > 0))
{
MessageBox.Show(String.Format("Hi there {0}!!, you have reserved a Seat at Row: {1} in Seat Number : {2}", resp.Name, resp.Row, resp.Seat));
}
else if (resp.erroresp != true)
{
if ((resp.Row < 1) && (resp.Seat < 1))
{
MessageBox.Show(String.Format("Sorry, your selected Seat has been taken, however there is an available seat at row {0} in seat {1}", resp.Row, resp.Seat));
}
}
}
