体育场馆系统场地预约缴费c#代码

以下是一个简单的场地预约和缴费的 C# 代码示例：

using System;
using System.Collections.Generic;

namespace SportsBookingSystem
{
    // 场馆类别枚举
    enum VenueType
    {
        BasketballCourt,
        BadmintonCourt,
        SwimmingPool,
        Gym
    }

    // 预约状态枚举
    enum BookingStatus
    {
        Available,
        Booked,
        Paid
    }

    // 场地类
    class Venue
    {
        public VenueType Type { get; set; }
        public int Capacity { get; set; }
        public decimal Price { get; set; }
        public List<Booking> Bookings { get; set; }

        public Venue(VenueType type, int capacity, decimal price)
        {
            Type = type;
            Capacity = capacity;
            Price = price;
            Bookings = new List<Booking>();
        }

        // 预约场地
        public Booking Book(DateTime startTime, DateTime endTime, int numOfPeople)
        {
            if (numOfPeople > Capacity) // 容量不足
            {
                return null;
            }

            foreach (Booking booking in Bookings)
            {
                if (startTime >= booking.StartTime && startTime < booking.EndTime ||
                    endTime > booking.StartTime && endTime <= booking.EndTime) // 时间冲突
                {
                    return null;
                }
            }

            Booking newBooking = new Booking(startTime, endTime, numOfPeople);
            Bookings.Add(newBooking);
            return newBooking;
        }
    }

    // 预约类
    class Booking
    {
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public int NumOfPeople { get; set; }
        public BookingStatus Status { get; set; }

        public Booking(DateTime startTime, DateTime endTime, int numOfPeople)
        {
            StartTime = startTime;
            EndTime = endTime;
            NumOfPeople = numOfPeople;
            Status = BookingStatus.Booked;
        }

        // 缴费
        public void Pay()
        {
            Status = BookingStatus.Paid;
        }
    }

    // 场馆管理类
    class VenueManager
    {
        private List<Venue> venues;

        public VenueManager()
        {
            venues = new List<Venue>();
            venues.Add(new Venue(VenueType.BasketballCourt, 10, 50));
            venues.Add(new Venue(VenueType.BadmintonCourt, 8, 30));
            venues.Add(new Venue(VenueType.SwimmingPool, 50, 100));
            venues.Add(new Venue(VenueType.Gym, 20, 80));
        }

        // 预约场地
        public Booking BookVenue(VenueType type, DateTime startTime, DateTime endTime, int numOfPeople)
        {
            foreach (Venue venue in venues)
            {
                if (venue.Type == type)
                {
                    return venue.Book(startTime, endTime, numOfPeople);
                }
            }

            return null;
        }

        // 缴费
        public void PayBooking(Booking booking)
        {
            booking.Pay();
        }
    }

    // 测试程序
    class Program
    {
        static void Main(string[] args)
        {
            VenueManager venueManager = new VenueManager();

            // 预约篮球场
            Booking basketballBooking = venueManager.BookVenue(VenueType.BasketballCourt, new DateTime(2021, 6, 1, 10, 0, 0), new DateTime(2021, 6, 1, 12, 0, 0), 8);
            if (basketballBooking != null)
            {
                Console.WriteLine("预约成功！场地类型：" + basketballBooking.Type + "，开始时间：" + basketballBooking.StartTime + "，结束时间：" + basketballBooking.EndTime + "，人数：" + basketballBooking.NumOfPeople);
                venueManager.PayBooking(basketballBooking);
                Console.WriteLine("缴费成功！");
            }
            else
            {
                Console.WriteLine("预约失败！");
            }

            // 预约游泳池
            Booking swimmingBooking = venueManager.BookVenue(VenueType.SwimmingPool, new DateTime(2021, 6, 2, 14, 0, 0), new DateTime(2021, 6, 2, 16, 0, 0), 30);
            if (swimmingBooking != null)
            {
                Console.WriteLine("预约成功！场地类型：" + swimmingBooking.Type + "，开始时间：" + swimmingBooking.StartTime + "，结束时间：" + swimmingBooking.EndTime + "，人数：" + swimmingBooking.NumOfPeople);
                venueManager.PayBooking(swimmingBooking);
                Console.WriteLine("缴费成功！");
            }
            else
            {
                Console.WriteLine("预约失败！");
            }

            Console.ReadLine();
        }
    }
}

代码中使用了类、枚举和列表等 C# 的基本语法，实现了场地预约和缴费的功能。需要注意的是，代码中的时间、人数和价格等参数都是根据实际情况进行设置的，具体实现时需要根据需求进行调整。
