我需要基于控制台的飞机座位预订代码（用c＃编写）的帮助。
尝试实施：
以下是我认为与我问的问题相关的飞机类的代码，如果有必要我可以提供更多（座位方法已经简化，因为它非常大），谢谢：
public static void seating()
{
Console.Write("Key: " + "* - Available " + " X - Occupied" + "\n" + "\n");
//FC
Console.Write(" \tA\tB\tC\tD\tE\tF");
Console.Write("\n");
Console.Write("Row 1\t");
Console.Write(airchar[0, 0]);

答案 0 :(得分：1)
我在表单上快速思考以改进您的解决方案建模。我相信它可以以更好的方式完成，但这可以是一个良好的开端。
似乎您不仅需要存储座位信息，还需要随意快速找到它。所以我制作了一系列物品来帮助按位置或乘客名称存储，更换和查找座位。希望它有所帮助。

下面我做了一个关于如何使用这些类的快速演示代码。我想这可以让您在实施应用程序时更轻松。您只需要像输入一样从输入中获取数据。
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();
}
这是您的应用程序的实际示例。将此代码放入您的Program类（使用Main方法的类）。
static AirplaneSeating seating;
static void Main(string[] args)
{
seating = new AirplaneSeating();
Options();
}
static void 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;
}
}
