            }
            List<Subject> sub = new List<Subject>();
        }
        List<Department> dep = new List<Department>();

        public void getdata()
        {
            List<Student> stu = new List<Student>();
        }
    }

}

Answer 1

您可以从：

开始

class Student
{
    string studentname;

    public Student(string studentname) {
        this.studentname = studentname;
    }

    public List<Department> Departments = new List<Department>();
}

class Department
{
    string departmentname;

    public Department(string departmentname) {
        this.departmentname = departmentname;
    }

    public List<Subject> Subjects = new List<Subject>();
}

class Subject
{
    string subjectname;

    public Subject(string subjectname) {
        this.subjectname = subjectname;
    }
}

以这种方式使用上述结构：

Student s = new Student("Student 1");
Department d = new Department("Department A");
s.Departments.Add(d);
d.Subjects.Add(new Subject("Subject A"));
