在另一个对象中实例化一个对象？（c#）

首先，我想说，如果这是一个愚蠢的问题，我真的很抱歉，但我刚刚开始学习课程，我认为我能理解它，但这让我很困惑，所以我似乎没有

我在做一门C#OOP edx课程，我必须在不同的课堂文件中设置5个班级（学生、教师、网络图、学位、课程），任务如下：

实例化一个名为信息技术的UProgram对象

在UProgram对象中实例化一个Degree对象，如bacher

在Degree对象内实例化一个名为softing的课程对象

完成了，（希望）没有问题

和3嗯

我是怎么想的（记住，我是个初学者）： 首先，我想到了嵌套类，但我不确定它们是如何工作的，也不认为我可以将类放入不同的文件中，因为它们应该嵌套（？） 然后我尝试了一些构造函数，但我不知道如何使它工作

所以现在我的最后一次尝试是在类内创建方法（除了教师和学生，因为他们不会有任何“属于他们”的东西，就像一门课程有学生和教师属于它一样）

所以我有一个方法，形式是（-假设我们在学位班，有一个方法为这个学位创建几个课程-）：

在我使用它之前，我必须写下

Course softeng = new Course();

在我完成任务的3.点之前，我先做一个课程类的实例

整个代码：

我知道，我知道，这很复杂，我甚至不确定这是否是好的，但这是我能想到的全部，如果你们中的任何人能帮助我，我将非常感激（语气不会让我哭泣）

再次感谢您，很抱歉代码如此混乱，呃，我试过了

这个措词看起来确实有点奇怪，但我相信他们只是说这个类应该包含它要“包含”的类型的属性，并在构造函数中实例化它。例如：

public class Degree
{
    public Course Course { get; set; }

    public Degree()
    {
        Course = new Course();
    }
}

public class Course
{
    public Student Student { get; set; }

    public Course()
    {
        Student = new Student();
    }
}

public class Student
{
    public Student()
    {

    }
}

创建学位实例时，它将在其中创建课程实例，这将在其中创建学生实例。因此，学位包含包含学生的课程

上面的示例使用构造函数实例化这些属性，但由于它们是公共属性，因此也可以从外部创建它们（在这种情况下，上面的构造函数是不必要的）：

仅作几点评论：

我很怀疑你是否需要继承。例如：学生：课程-我怀疑“学生就是课程”：。所以，你可能需要一些构图。我不知道（也不记得）你照片中的钻石到底是什么意思，但我可以猜到，填充的钻石——是一件物品（或者至少是一件，不确定），而空的钻石意味着很多物品。 下面是我的做法（您可以将每个类拆分为单独的文件）：

public类文件
{
公共字符串名称{get；set；}
公共度{get；set；}
公共图（字符串名称、度）
{
名称=名称；
度=度；
}
}
公立学位
{
公共字符串名称{get；set；}
公共课程{get；set；}
公共学位（字符串名称、课程）
{
名称=名称；
课程=课程；
}
}
公共课
{
公共列表教师{get；set；}
公共列表学生{get；set；}
公共字符串名称{get；set；}
公共课程（字符串名称、教师列表、学生列表）
{
名称=名称；
教师=教师；
学生=学生；
}
}
公共班主任
{
公共字符串名{get；set；}
公共字符串LastName{get；set；}
}
公立班学生
{
公共字符串名{get；set；}
公共字符串LastName{get；set；}
}

主要功能：

static void Main(string[] args)
    {
        var teachers = new List<Teacher>
        {
            new Teacher
            {
                FirstName = "Colin",
                LastName = "Firth"
            }
        };
        var students = new List<Student>
        {
            new Student
            {
                FirstName = "Mary",
                LastName = "Sue"
            },
            new Student
            {
                FirstName = "Joseph",
                LastName = "Jojo"
            }
        };

        var softEngCourse = new Course("Software Engineering", teachers, students);
        var bachelorDegree = new Degree("Bachelor", softEngCourse);

        var technologyProgram = new UProgram("Technology", bachelorDegree);

        Console.ReadLine();
    }

static void Main（字符串[]args）
{
var教师=新名单
{
新教师
{
FirstName=“科林”，
LastName=“弗斯”
}
};
var students=新列表
{
新生
{
FirstName=“玛丽”，
LastName=“苏”
},
新生
{
FirstName=“约瑟夫”，
LastName=“Jojo”
}
};
var softEngCourse=新课程（“软件工程”，教师，学生）；
var bachelorDegree=新学位（“学士”，软化课程）；
var technologyProgram=新图谱（“技术”，学士学位）；
Console.ReadLine（）；
}

我仍然不确定这是否正是您对课程的期望，这就是我将如何编写这样的代码（有一些小改动，但在这里并不重要）。 为什么会这样？因为当一个对象显式地接收到它所需要的一切时，它几乎总是在“工作”状态下构建一个对象，而不是创建一个将在“无效”状态下启动的原始对象。第二，它
