将对象的内容添加到列表而不是参数类型

希望我描述的足够正确和清楚。我试图保存由用户输入的多个详细信息，并将它们保存到列表。然而，目前我这样做的方式是只保存对象类型/名称，而不是数据。下面是我的代码，我如何保存对象的数据，而不是对象的名称?

Student stud = new Student();
stud.Enter_Student();
_studentList.Add(stud);

class Student : Person
{
    public string StudentId { get; private set; }
    public string Subject { get; private set; }
    //string[] _studentdb = new string[4];
    public Student()
    {
        StudentId = "abc123";
        Subject = "Building Subject";
    }
    public void Enter_Student()
    {
            this.Person_Prompt_Print(); //Prompts for user
            this.Address_Prompt_Print();
            this.Contact_Prompt_Print();
            Console.SetCursorPosition(4, 18);
            Console.WriteLine("Student ID:");
            this.Enter_Person(); // Inputs from user
            this.Enter_Address();
            this.Enter_Contacts();
            StudentId = Console.ReadLine();
            Console.SetCursorPosition(30, 18);
    }
}

person类的日期样本

class Person
{
    Tidyup tidy = new Tidyup();
    public string FirstName { get; private set; }
    public string Surname { get; private set; }
    public string MiddleName { get; private set; }
    public string AddressLine1 { get; private set; }
    public string AddressLine2 { get; private set; }
    public string Town { get; private set; }
    public string Postcode { get; private set; }
    public string Email { get; private set; }
    public string Telephone { get; private set; }

    public Person()
    {
        FirstName = "Name";
        Surname = "Surname";
        MiddleName = "Middle Name";
        AddressLine1 = "Address";
        AddressLine2 = "Address Ln2";
        Town = "Town";
        Postcode = "<xxx>/<xxx>";
        Email = "name@buildright.ac.uk";
        Telephone = "0800 0000000";
    }
    public void Person_Prompt_Print()
    {
        // Program Frame
        tidy.Line_Top();
        tidy.Line_Base();
        tidy.Sides_Left();
        tidy.Sides_Right();
        Console.SetCursorPosition(4, 2); //Prompts for user
        Console.WriteLine("FirstName:");
        Console.SetCursorPosition(4, 4);
        Console.WriteLine("Surname:");
        Console.SetCursorPosition(4, 6);
        Console.WriteLine("Middle Name:");
    }
    public void Address_Prompt_Print()
    {
        Console.SetCursorPosition(4, 8); //Prompts for user
        Console.WriteLine("House Number/Name:");
        Console.SetCursorPosition(4, 10);
        Console.WriteLine("Street:");
        Console.SetCursorPosition(4, 12);
        Console.WriteLine("Town:");
        Console.SetCursorPosition(4, 14);
        Console.WriteLine("Post Code:");
    }
    public void Contact_Prompt_Print()
    {
        Console.SetCursorPosition(4, 16);
        Console.WriteLine("Email:");
        Console.SetCursorPosition(4, 18);
        Console.WriteLine("Telephone:");
    }
    public void Enter_Person()
    {
        Console.SetCursorPosition(30, 2); // Inputs from user
        FirstName = Console.ReadLine();
        Console.SetCursorPosition(30, 4);
        Surname = Console.ReadLine();
        Console.SetCursorPosition(30, 6);
        MiddleName = Console.ReadLine();
    }
    public void Enter_Address()
    {
        Console.SetCursorPosition(30, 8);  // Inputs from user
        AddressLine1 = Console.ReadLine();
        Console.SetCursorPosition(30, 10);
        AddressLine2 = Console.ReadLine();
        Console.SetCursorPosition(30, 12);
        Town = Console.ReadLine();
        Console.SetCursorPosition(30, 14);
        Postcode = Console.ReadLine();
    }
    public void Enter_Contacts()
    {
        Console.SetCursorPosition(30, 16);
        Email = Console.ReadLine();
        Console.SetCursorPosition(30, 18);
        Telephone = Console.ReadLine();
    }
} // End of Class

最后我通过一个简单的嵌套foreach循环打印出来

public void Print_all_student()
{
    Console.Clear();
    foreach (Student t in _studentList)
    {
        // print another list items.
        foreach (Student t1 in _studentList)
        {
            Console.WriteLine("/" + t + "/" + t1);
        }
    }
    Console.ReadKey();
}

如果有人能帮助我了解我错过了什么，以及如何访问数据打印出来，我将不胜感激。
