Question about passing inherited objects in methods

Last Modified: 2015-03-01
Hi experts,

I have a class called student that inherits from a person class.  I wanted to update the student's name only so I created a method in my person repository called Update(Person p) that accepts a person.

public Person
public string Name;

public Student : Person
public string StudentID
Person Repository
public void Update(Person p)

xxx some where in my program xxx

Student student = Repository.GetStudent();
student.Name = "Jack";

I know that the Update method will contain a person object that I can interact with but HOW is the data being sent to the repository? Does the student object get sent to the repository or does .Net automatically extract the Person object from the Student object then sends it to the repository?
