Level Inheritance

[Weste]

I am attempting to learn OOP. The book I am using has the examples in C++. I am attempting to modify the code in C#. .Net doesn't like Personisplay(); in the Student class below. Can someone tell me how this should be modified with C#. Thanks.

using System;

namespace LevelInheritance
{
/// <summary>
/// Summary description for Person.
/// </summary>
public class Person
{
protected int m_ID;
protected string m_First;
protected string m_Last;

public Person()
{

m_ID = 0;
m_First = "\0";
m_Last = "\0";
}

public virtual void Display()
{
Console.WriteLine("ID: " + m_ID +
"\rFirst: " + m_First +
"\rLast: " + m_Last);
}

public void Write(int ID, string First, string Last)
{
m_ID = ID;
m_First = First;
m_Last = Last;
}
}

class Student: Person
{
protected int m_Graduation;

public new virtual void Display()
{
Personisplay();
Console.WriteLine("Graduation: " + m_Graduation);
}

public void Write(int ID, string First, string Last, int Graduation)
{
Person:Write(ID, First, Last);
m_Graduation = Graduation;
}

public Student()
{
m_Graduation = 0;
}
}

Try

public override void Display()
{
Person:Display();
Console.WriteLine("Graduation: " + m_Graduation);
}

It looks like something wigged out in your code block, PlausiblyDamp. Were your recomending Person.Display()? Wouldn't you need to do base.Display() becuase Display is a non-static method?

public override void Display()
{
   base.Display();
   Console.WriteLine("Graduation: " + m_Graduation);
}

The only colon format I know of is used for labeling goto's so as far as I know, Personisplay() will not work.

My bad - I just copied, pasted and tweaked the code without checking it...

About mskeel's comment ("...wigged out..."), I edited PM's message to turn off smilies. The line "Personisplay();" was interpreted as "" and, I guess in the code brackets, turned it into a big mess!
