Hi all,
I am trying to get my head arround the classes and inheritance.
I understand the thoery quite well I beleive but I am having trouble getting the structure of the code straight in my head.

I have a class named Person, and a class named User which inherits the Person class.

In my working example i wish to log the user in.

To do this I had planned on making the User constructor take the log in details, Username and Password.

My intension was the same for the Person to a point, the personID would be passed to the constructor.

My question is how do I run the two constructors to create a complete user with all the attributes of a person?

Or should I be looking at this all together differently?

PS.
I did not wish to have a set accessor to the PersonID or UserID. Which started my problems as I don't now how to set the PersonID varaible form the User class

======================================

My idea is to write overloaded constructors in User.
public User(string name,string pwd)
{
//your code
}
public User(string name,string pwd,int perrsonid) : base(personid)
{
//your code
}

Everybody is talented but i am intelligent enough to learn from their knowledge.

I think your mean is getting all(or necessary)fields from your parent class
and giving them to your child class
------------
//C#
class Parent
//declare all(or necessary)fields for childs as public(or protected)
public int necessaryForAll;
protected int necessaryForChilds;
private int unnecessaryForOtherClasses;
//your constructer
public Parent(,,,)//could have more parameters
{
//initialize all the fields if you forget some of them compiler gives them the default value(null for classes,0 for integers,.....)
}
//now Derivation
Class Child:Parent
{
//Declare the new necessary fields in addition to-
//your fileds (public or protected) in Parent class
//***IMPORTANT...Then you should exactly call
//the constructer with the same parameters as parameters in your parent
//constructor *****Because here you want to load the necessary fields of
//your parent class in addittion the fields of your child class******
public child:base(,,,)
{
//initialize all new fields declared in your child class
}

Hope This could help you.

Thank you both, I'll try out these ideas.
