带类的WriteLine [英] WriteLine with a class

问题描述

我正在编写SchoolApp程序以了解C#，并且我要尝试执行以下主要功能:

I'm making a SchoolApp program to learn about C# and I have this main function that I'm trying to make work:

namespace SchoolApp
{
    class Program
    {
        public static void Main(string[] args)
        {
            School sch = new School("Local School");
            sch.AddStudent(new Student { Name = "James", Age = 22 }); // this function
            sch.AddStudent(new Student { Name = "Jane", Age = 23 });
            Console.WriteLine(sch); // this implementation
        }
    }
}

学校课程:

namespace SchoolApp
{
    class School
    {
        public string name;

        public School()
        {
        }

        public School(string the_name)
        {
            name = the_name;
        }

        public void AddStudent(Student student)
        {

        }
    }
}

学生班: 命名空间SchoolApp

Student class: namespace SchoolApp

{
    class Student
    {
        public int Age;
        public string Name;
        public Student()
        {
            Age = 0;
            Name = "NONAME";
        }

        public string _name 
        {
            get
            {
                return this.Name;
            }
            set
            {
                Name = value;
            }
        }
        public int _age
        {
            get
            {
                return this.Age;
            }
            set
            {
                Age = value;
            }
        }

    }
}

我是C#的新手，我对应该如何制作AddStudent以及如何使用WriteLine编写类非常困惑.输出应遵循以下几行:

I'm new to C# and I am pretty lost as to how I should make the AddStudent and how to work with the WriteLine to write the class. The output should be along these lines:

学校:当地学校 詹姆斯22岁 简，23

School: Local School James, 22 Jane, 23

有人建议使用List<>我遇到了同样的问题，那就是对它的了解不足.

Someone suggested using List<> I hit the same problem of not knowing enough about it.

谢谢大家的快速答复.我已经开始使用它，现在将深入阅读答案，这样我就不必再问相关问题了！

Thank you all for your extremely fast answers. I got it working and will now commense reading the answers in depth so I don't have to ask related questions again!

推荐答案

在您的School类中，您似乎想拥有一个私有的Student列表.列表很简单，在您的情况下，它采用通用类型Student，您可以在其中添加项目或从中删除项目.

In your School class it looks like you want to have a private list of Students. List is simple, it takes in a generic type, in your case Student and you can add and remove items to/from it.

在您的School类中使用:

 private List<Student> students; 

在您的AddStudent代码中，您可以简单地使用:

And in your AddStudent code you could simply use:

students.Add(student);  // student is the variable being passed in and students is the list.  NOTE: You will have to make sure students is intalized to a new List of Student.  students = new List<Student>();

看看以下链接. MSDN是适当的文档，但是dotnetperls对于像这样的简单东西很有用.

Take a look at the following links. MSDN is the proper documentation, but the dotnetperls is good for simple stuff like this.
