Question

我目前正在开展一个项目，我被要求为小型企业制作一个程序（在这种情况下是一个小型电影院），我可以为各种产品和客户记录和打印收据。

到目前为止，我所掌握的是一系列记录客户想要订购的代码。

如何制作另一个存储和计算价格的课程，并打印出收据的样子？

我不是要求答案，只是一些指导。

如果您想要上课，您可能想要创建一个代表通用产品的类，然后有一个方法从该产品中获取详细信息

因为我没有更好的事情要做，所以我给你做了一个SSCCE。它过于简化，但它满足了您对特定情况的要求，并使用了一个对象。

我确信你足够聪明，可以使用一些概念来满足你的特定需求。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{

    public class Product
    {
        public string description;
        public double price;
        //normally you want to use eitehr an int for price(representing cents) or a decimal type, instead of double
        //just using a double here for the sack of simplicity
        // you'll also want to use properties instead of variable fields, but i'm using variable fields for simplicity

        // constructor
        public Product(string description, double price)
        {
            this.description = description;
            this.price = price;
        }

        public string GetDetailLine()
        {
            // google "String.Format" for more information,
            // basically it replaces things in the {0} and {1}, with the other parameters
            // the ":c" in {1:c} part means format as currency
            return String.Format("You ordered {0}.  It costs: {1:c}", description, price);
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            List<Product> products = new List<Product>();


            Console.Write("Do You Want a Soda?   ");
            string input = Console.ReadLine();
            //the .ToUpper() part makes it upper case
            if (input.ToUpper() == "YES")
            {
                Product soda = new Product("soda", 2.50);
                products.Add(soda);
            }

            double total = 0; 
            for(int i = 0; i<products.Count; i++)
            {
                Console.WriteLine(products[i].GetDetailLine());
                total += products[i].price;
            }

            //you can also use Console.Writeline like String.Format
            Console.WriteLine("Your Total is:  {0:c}", total);


            // this is just to pause in-case you're debugging from visual studio
            Console.ReadLine();
        }
    }
}
