用C#创建疫苗表(编号、名称、注射量、保质期、价格)； 添加5条测试数据 实现增删改查

以下是用C#创建疫苗表并实现增删改查的示例代码：

using System;
using System.Collections.Generic;

namespace VaccineManagement
{
    class Vaccine
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public double Dosage { get; set; }
        public int ShelfLife { get; set; }
        public decimal Price { get; set; }
    }

    class Program
    {
        static List<Vaccine> vaccines = new List<Vaccine>();

        static void Main(string[] args)
        {
            // 添加5条测试数据
            vaccines.Add(new Vaccine { ID = 1, Name = "狂犬病疫苗", Dosage = 0.5, ShelfLife = 12, Price = 100 });
            vaccines.Add(new Vaccine { ID = 2, Name = "水痘疫苗", Dosage = 0.5, ShelfLife = 24, Price = 200 });
            vaccines.Add(new Vaccine { ID = 3, Name = "麻疹疫苗", Dosage = 0.5, ShelfLife = 36, Price = 300 });
            vaccines.Add(new Vaccine { ID = 4, Name = "百白破疫苗", Dosage = 0.5, ShelfLife = 48, Price = 400 });
            vaccines.Add(new Vaccine { ID = 5, Name = "流感疫苗", Dosage = 0.5, ShelfLife = 6, Price = 50 });

            while (true)
            {
                Console.WriteLine("请选择操作：");
                Console.WriteLine("1. 查看疫苗列表");
                Console.WriteLine("2. 添加疫苗");
                Console.WriteLine("3. 删除疫苗");
                Console.WriteLine("4. 修改疫苗信息");
                Console.WriteLine("5. 退出");

                string choice = Console.ReadLine();
                switch (choice)
                {
                    case "1":
                        ShowVaccines();
                        break;
                    case "2":
                        AddVaccine();
                        break;
                    case "3":
                        RemoveVaccine();
                        break;
                    case "4":
                        ModifyVaccine();
                        break;
                    case "5":
                        return;
                    default:
                        Console.WriteLine("无效的选择，请重新输入。");
                        break;
                }
            }
        }

        static void ShowVaccines()
        {
            Console.WriteLine("编号\t名称\t注射量\t保质期\t价格");
            foreach (var vaccine in vaccines)
            {
                Console.WriteLine($"{vaccine.ID}\t{vaccine.Name}\t{vaccine.Dosage}\t{vaccine.ShelfLife}\t{vaccine.Price}");
            }
        }

        static void AddVaccine()
        {
            Console.WriteLine("请输入疫苗信息：");
            Console.Write("编号：");
            int id = int.Parse(Console.ReadLine());
            Console.Write("名称：");
            string name = Console.ReadLine();
            Console.Write("注射量：");
            double dosage = double.Parse(Console.ReadLine());
            Console.Write("保质期：");
            int shelfLife = int.Parse(Console.ReadLine());
            Console.Write("价格：");
            decimal price = decimal.Parse(Console.ReadLine());

            vaccines.Add(new Vaccine { ID = id, Name = name, Dosage = dosage, ShelfLife = shelfLife, Price = price });

            Console.WriteLine("添加成功！");
        }

        static void RemoveVaccine()
        {
            Console.Write("请输入要删除的疫苗编号：");
            int id = int.Parse(Console.ReadLine());

            Vaccine vaccine = vaccines.Find(v => v.ID == id);
            if (vaccine != null)
            {
                vaccines.Remove(vaccine);
                Console.WriteLine("删除成功！");
            }
            else
            {
                Console.WriteLine("未找到该疫苗！");
            }
        }

        static void ModifyVaccine()
        {
            Console.Write("请输入要修改的疫苗编号：");
            int id = int.Parse(Console.ReadLine());

            Vaccine vaccine = vaccines.Find(v => v.ID == id);
            if (vaccine != null)
            {
                Console.WriteLine($"当前疫苗信息：{vaccine.ID}\t{vaccine.Name}\t{vaccine.Dosage}\t{vaccine.ShelfLife}\t{vaccine.Price}");
                Console.WriteLine("请输入修改后的疫苗信息：");
                Console.Write("名称：");
                vaccine.Name = Console.ReadLine();
                Console.Write("注射量：");
                vaccine.Dosage = double.Parse(Console.ReadLine());
                Console.Write("保质期：");
                vaccine.ShelfLife = int.Parse(Console.ReadLine());
                Console.Write("价格：");
                vaccine.Price = decimal.Parse(Console.ReadLine());

                Console.WriteLine("修改成功！");
            }
            else
            {
                Console.WriteLine("未找到该疫苗！");
            }
        }
    }
}

运行程序后，可按照提示进行操作。例如，选择“1. 查看疫苗列表”时，输出如下：

编号	名称	注射量	保质期	价格
1	狂犬病疫苗	0.5	12	100
2	水痘疫苗	0.5	24	200
3	麻疹疫苗	0.5	36	300
4	百白破疫苗	0.5	48	400
5	流感疫苗	0.5	6	50
