尋找班級指導

Question

我目前正在製作一個項目，要求我爲小企業製作節目（在這種情況下是一個小電影院），我可以在這裏爲各種產品和客戶錄製和打印收據。

我到目前爲止是一系列記錄客戶想要訂購的代碼。

我該如何着手製作另一個存儲並計算價格的課程，並向控制檯輸出收據的樣子？

我不是要求答案，只是一些指導。

如果你想使一個類時，你可能會想使一個類，將代表一個通用的產品，然後有一個方法，從該產品獲得詳細信息行

既然我沒有更好的辦法，我已經讓你成爲SSCCE。它過於簡化，但它滿足您對特定情況的要求，並使用一個對象。

我相信您足夠聰明，可以使用一些概念來滿足您的特定需求。

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(); 
     } 
    }
