使用C sharp编写一个自习室座位预订系统

好的，下面是一个简单的自习室座位预订系统的 C# 代码示例：

using System;
using System.Collections.Generic;

namespace SeatReservationSystem
{
    class SeatReservation
    {
        static void Main(string[] args)
        {
            // 初始化座位列表
            List<Seat> seats = new List<Seat>();
            for (int i = 1; i <= 30; i++)
            {
                Seat seat = new Seat(i);
                seats.Add(seat);
            }

            while (true)
            {
                Console.WriteLine("请选择操作：1. 预订座位 2. 取消预订 3. 显示座位状态 4. 退出");
                int choice = Convert.ToInt32(Console.ReadLine());

                switch (choice)
                {
                    case 1:
                        Console.WriteLine("请输入要预订的座位号：");
                        int seatNumber = Convert.ToInt32(Console.ReadLine());
                        if (seatNumber < 1 || seatNumber > 30)
                        {
                            Console.WriteLine("座位号无效，请重新输入！");
                            break;
                        }
                        Seat seat = seats[seatNumber - 1];
                        if (seat.IsReserved)
                        {
                            Console.WriteLine("该座位已被预订，请选择其他座位！");
                            break;
                        }
                        Console.WriteLine("请输入预订人姓名：");
                        string name = Console.ReadLine();
                        seat.Reserve(name);
                        Console.WriteLine("预订成功！");
                        break;
                    case 2:
                        Console.WriteLine("请输入要取消预订的座位号：");
                        seatNumber = Convert.ToInt32(Console.ReadLine());
                        if (seatNumber < 1 || seatNumber > 30)
                        {
                            Console.WriteLine("座位号无效，请重新输入！");
                            break;
                        }
                        seat = seats[seatNumber - 1];
                        if (!seat.IsReserved)
                        {
                            Console.WriteLine("该座位未被预订，无需取消预订！");
                            break;
                        }
                        seat.CancelReservation();
                        Console.WriteLine("取消预订成功！");
                        break;
                    case 3:
                        Console.WriteLine("当前座位状态如下：");
                        foreach (Seat s in seats)
                        {
                            Console.WriteLine("座位号：" + s.SeatNumber + "，状态：" + (s.IsReserved ? "已预订，预订人姓名：" + s.ReservedName : "未预订"));
                        }
                        break;
                    case 4:
                        Console.WriteLine("程序已退出！");
                        return;
                    default:
                        Console.WriteLine("无效操作，请重新选择！");
                        break;
                }
            }
        }
    }

    class Seat
    {
        public int SeatNumber { get; private set; }
        public bool IsReserved { get; private set; }
        public string ReservedName { get; private set; }

        public Seat(int seatNumber)
        {
            SeatNumber = seatNumber;
            IsReserved = false;
            ReservedName = "";
        }

        public void Reserve(string name)
        {
            IsReserved = true;
            ReservedName = name;
        }

        public void CancelReservation()
        {
            IsReserved = false;
            ReservedName = "";
        }
    }
}

该系统使用了一个 `Seat` 类来表示座位，包含座位号、预订状态和预订人姓名等属性，以及 `Reserve` 和 `CancelReservation` 方法来预订和取消预订座位。主程序中使用一个 `List<Seat>` 来管理所有座位，通过不断循环读取用户输入的操作选择，来实现预订、取消预订和显示座位状态等功能。

该代码只是一个简单的示例，实际项目中需要根据需求进行更加详细的设计和开发。
