将用户输入添加到类列表

Question

我有一个计算机分配我卡住了。 我必须创建一个大学课程列表，并让用户添加或删除该列表。我有基本列表和我的printmenu循环，但无法弄清楚如何将用户输入到classlist中的另一个类中。

这里是我的main.cs迄今....

using System; 
using System.Collections.Generic; 

namespace Lab04 
{ 
    class MainClass 
    { 
     public static string prefix; 
     public static int coursenumber; 
     public static int credithours; 
     public static string coursedescription; 


     public static void Main (string[] args) //creates 4 courses (used some leftover Lab 03 data and some new) 
     { 

      Course c1 = new Course(); 
      Course c2 = new Course("ENGL", 1102, 3, "Second level class for English Composition."); 
      Course c3 = new Course("GEOG", 1113, 4, "This is an online lab course for Geography."); 
      Course c4 = new Course("BWV", 101, 2, "This is basket weaving on a college level, for those of you who need a break."); 


      Console.WriteLine ("Here are your current courses for this semester:"); 

      List<Course> classlist = new List<Course>(); 
      classlist.Add (c1); 
      classlist.Add (c2); 
      classlist.Add (c3); 
      classlist.Add (c4); 

      foreach(Course c in classlist) 
       Console.WriteLine(c + " "); 
      Console.WriteLine(); 

      int choice; 
      do { 
      PrintMenu(); 
      choice = Int32.Parse (Console.ReadLine()); 
      ProcessChoice(choice); 
      } while (choice != 4); 
      Console.WriteLine ("Thank you for using this system."); 

     } 

     public static void PrintMenu() //print menu for user input 
     { 
      Console.WriteLine("Main Menu:"); 
      Console.WriteLine("1. Add a Course to the list."); 
      Console.WriteLine("2. Delete a Course from the list."); 
      Console.WriteLine("3. Print your class schedule."); 
      Console.WriteLine("4. Exit this System."); 
      Console.WriteLine("Please enter your numerical choice."); 

     } 

     static void ProcessChoice(int c) // do while loop code for user input 
     { 
      if (c == 1) 
      { 
       Console.WriteLine ("Please enter the Course prefix."); 
       prefix = Console.ReadLine(); 
       Console.WriteLine ("Please enter the Course number."); 
       coursenumber = Int32.Parse(Console.ReadLine()); 
       Console.WriteLine ("How many credit hours is this course worth?"); 
       credithours = Int32.Parse(Console.ReadLine()); 
       Console.WriteLine ("Please enter a short course description."); 
       coursedescription = Console.ReadLine(); 
      } 

      else if (c == 2) 
      { 
       Console.WriteLine ("Which course would you like to remove?"); 
      } 

      else if (c == 3) 
      { 
       Console.WriteLine ("Displaying current class schedule."); 


      } 
     } 
    } 
} 

我看了这个帖子Adding multiple user input to a List c#，但由于它只是增加了整数，而不是全班同学的名单，也没有回答我的问题

有多种方法。一种方法是制作全球课程表

public void ProcessChoice(int c) 
{ 
    if (c == 1) 
    { 
     //Get the input from console 
     classlist.Add(new Course{ 
      prefix = prefix, 
      coursenumber = coursenumber, 
      credithours = credithours, 
      coursedescription = coursedescription 
     }); 
    } 
}
