从程序返回列表(新手) [英] return a list from program (newbeginner)

问题描述

你好，

我是C#的新手
我还不了解所有事物如何相互连接，例如类和对象...

我创建了一个简单的项目.
我的目标是拥有两个不同的公共班级.

myfirst类(包含并列出"companyInfo")

mySecondClass(调用companyinfo列表)

从静态void Main(string [] args)中警报companyInfo中的所有项目

有人可以帮我吗?

请参阅下面的代码:

Hello People,

I have created a a simple project.
My goal it is to have two different public classes.

mySecondClass (calls the companyinfo list)

from static void Main(string[]args) alert all items in the companyInfo

Could someone help me?

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


namespace MyProgram
{
     }
     class Program
    {
        static void Main(string[] args)
        {
            {

                CompanyMain CCinfo = new CompanyMain();         
           
            }
        }


        public class myList
        {
            static List<string> CompanyInfo()
            {
                List<string> CompanyInformation = new List<string>();
                CompanyInformation.Add("test1");
                return CompanyInformation;
            }
        }

        public class CompanyMain
        {

            myList CompanyInfo = new myList();
            
        }

     }

在此先谢谢您

Thank you in advance

推荐答案

对不起，我的英语...

首先，您需要更改公司信息"字段的访问修饰符，因为未指定时，默认情况下将其设为私有，并且您无法在类中看到它.

Sorry for my english...

First you will need to change access modifier of Company Info field, because when it isn''t specified, by default take private and you can''t see it out the class.

public class CompanyMain
        {
 
           public myList Company<big></big>Info = new myList();
            
        }

之后，主要可以看到CompanyInfo字段，并且可以对其进行操作.

After that, in the main you can see the CompanyInfo field and you can manipulate it.

static void Main(string[] args)
       {
           {
               CompanyMain CCinfo = new CompanyMain();
           foreach(var item = CCinfo.CompanyInfo.CompanyInfo()){
                 //

             }
           }
       }

为了循环浏览列表中的所有项目，您需要使用 foreach [^ ]语法.

例如

In order to cycle through all the items in a list you need to use the foreach[^] syntax.

e.g.

foreach s in CCinfo.CompanyInfo()
 ''do something with the company info here...
next
