C#实现一个控制台的点餐系统

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 控制台操作尝试{  class Program  {    static void Main(string[] args)    {      int price = 0;      Console.WriteLine("欢迎来吃饭");      Console.WriteLine("===================================================================");      Console.WriteLine("1.糖醋里脊 24元");      Console.WriteLine("2 红烧茄子 14元");      Console.WriteLine("3.千页豆腐 18元");      Console.WriteLine("4.蚂蚁上树 20元");      Console.WriteLine("5.红烧猪蹄 36元");      Console.WriteLine("6.宫保鸡丁 32元");      Console.WriteLine("===================================================================");      Console.WriteLine("请按菜品序号点餐，0号键结算");      Console.WriteLine("===================================================================");      while (true)      {        int index = int.Parse(Console.ReadLine());        if (index==1)        {          Console.WriteLine("您点的是糖醋里脊 24元");          price += 24;        }        if (index == 2)        {          Console.WriteLine("您点的是红烧茄子 14元");          price += 14;        }        if (index ==3)        {          Console.WriteLine("您点的是千页豆腐 18元");          price += 18;        }        if (index == 4)        {          Console.WriteLine("您点的是蚂蚁上树 20元");          price += 20;        }        if (index == 5)        {          Console.WriteLine("您点的是红烧猪蹄 36元");          price += 36;        }        if (index == 6)        {          Console.WriteLine("您点的是宫保鸡丁 32元");          price += 32;        }        if (index ==0)        {          Console.WriteLine("您总共消费{0}元",price);        }              }      //Console.ReadLine();    }  }}
