予約システムの配列要素にユーザー定義の名前を割り当てる

Question

私のコンソールベースの飛行機の座席予約コード（c＃で書かれています）のヘルプが必要です。

実装しよう：乗客名/座席番号によって

• 検索の座席の下に

は、私ができる、私は私が求めている問題に関連すると思った飛行機のクラスからのコードです必要に応じて、より多くを提供（それは非常に大きかったので、座席の方法が簡素化されました）、ありがとう：

を私はするフォームにすぐに思いましたソリューションのモデリングを改善します。私はそれがより良い方法で行えると信じていますが、これは良いスタートになることがあります。

座席情報を保存するだけでなく、気軽に見つけることができるようです。そこで私は座席を格納、変更、位置や乗客の名前で見つけることを支援するオブジェクトのセリフを作成しました。それが役に立てば幸い。

ヘルパークラスコード：

public class AirplaneSeating 
{ 
    private List<Seat> seats; 

    public AirplaneSeating()

     seats = new List<Seat>(); 

     // Filling FC Rows 
     for (byte row = 1; row <= 5; row++) 
      for (byte column = 1; column <= 4; column++) 
       seats.Add(new Seat(row, column)); 

     // Filling EC Rows 
     for (byte row = 6; row <= 35; row++) 
      for (byte column = 1; column <= 6; column++) 
       seats.Add(new Seat(row, column)); 
    } 

    // You can use this indexed property to search for a seat by it's address 
    public Seat this[string address] 
    {

       var col = address[end]; 

       return seats.First(

私は、これらのクラスを使用する方法の簡単なデモコードを作っ下。私はあなたのアプリケーションを実装するときに、これがあなたの人生をはるかに簡単にするだろうと思う。あなたがしていたように、入力からデータを取り出すだけで済みます。

static void Main(string[] args) 
{ 
    var seating = new AirplaneSeating(); 

    // Use PrintToConsole to print seating to screen. 
    seating.PrintToConsole(); 

    // You can find a specific seat by its position. 
    var seat1 = seating["1A"]; // Gives me seat 1A 
    var seat2 = seating[1, 1]; // Also gives me seat 1A 

    // Then you can put a passenger on this seat if you want. 
    seat2.Passenger = "Jhon"; 

    // When you set a passenger name to the seat, its status will change. 
    Console.WriteLine("Seat 1A status is {0}.", seat1.Status); // Occupied 

    // You can find a specific seat by passenger name. 
    // This line of code gives me seat 1A, wich is now Jhon's seat. 
    var occupiedSeat1 = seating.FindSeatOccupiedBy("Jhon"); 

    // You can find by typing a part of the passenger name, 
    // and you don't need to worry about capitalization 
    var occupiedSeat2 = seating.FindSeatOccupiedBy("JHO"); 

    // You can print seat information on console. 
    Console.WriteLine("Seat {0} is occupied by {1}.", 
     occupiedSeat2.Position, occupiedSeat2.Passenger); 

    Console.ReadLine(); 
} 

これは実際のアプリケーションの例です。このコードをProgramクラス（Mainメソッドを持つクラス）に入れてください。

static AirplaneSeating seating; 

static void Main(string[] args) 
{ 
    seating = new AirplaneSeating(); 
    Options(); 
}

    bool optionOk = false; 
    byte option = 0; 

    while (!optionOk)

     Console.Clear(); 
     Console.WriteLine("Select from the following menu:"); 
     Console.WriteLine("1. To Add Passenger"); 
     Console.WriteLine("2. To View Seating"); 
     Console.WriteLine("3. To View Passenger List"); 
     Console.WriteLine("4. Quit Application" + "\n"); 

     byte.TryParse(Console.ReadLine(), out option); 

     if (option >= 1 && option <= 4) 
     { 
      optionOk = true; 
     } 
    } 

    switch (option) 
    { 
     case 1: 
      Console.Clear(); 
      seating.ReserveSeat(); 
      Console.WriteLine(); 
      Console.Write("Please press enter to return to main menu."); 
      Console.ReadLine(); 
      Console.Clear(); 
      Options(); 
      break; 

     case 2: 
      Console.Clear(); 
      seating.PrintToConsole(); 
      Console.WriteLine(); 
      Console.Write("Please press enter to return to main menu."); 
      Console.ReadLine(); 
      Console.Clear(); 
      Options(); 
      break; 

     case 3: 
      Console.Clear(); 
      seating.PrintPassengersToConsole(); 
      Console.WriteLine(); 
      Console.Write("Please press enter to return to main menu."); 
      Console.ReadLine(); 
      Console.Clear(); 
      Options(); 
      break; 

     case 4: 
      Environment.Exit(0); 
      break; 
    } 
}
