Why the compiler is giving me an error of Age ?

Question

Base Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Assignment_3_Csharp
{
internal class Person
{
private int age;
public virtual int SETAGE
{
get
{
return age;
}
}
}
}

Another Class

ng System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Assignment_3_Csharp
{
internal class STUDENTANDTEACHERTEST
{
static void Main(string[] args)
{

Person person = new Person();

Console.WriteLine("Hello");

Student student = new Student();

student.Age = 21;

Console.WriteLine("Hello , my age is : {0} ");

}
}
}

Answer 1

your age property is not well defined

there is different ways to do this:

This is quite common and usually enough
class Person
{
public int Age {get; set;}
}

use this if the age variable does more actions when it's being set. This is where you would do validation.
class Person
{
private int _age;
public int Age
{
get
{
return _age;
}
set
{
_age = value;
}
}

Answer 2

oh yeah, but I have to be honest, even after my many years of experience I'm still googling the basics!

There is so much to learn and so much concepts to understand. it's impossible to know it all.

If syntax is difficult for you, I'd recommend you to explore other languages after learning the basics. Knowing more languages helps a lot to break through this syntax barrier.

Answer 3

Thank you Apollo-Roboto but I find OOP very hard , any tips how it can get easier ?
I mean the theory of OOP 4 pillars are easy but applying them into code is the challenge

Answer 4

I like to see a class as a collection of information. From your example, you can say that you have a collection of information for a student. The class is just there to keep it together.

Answer 5

And the syntaxes will get easier by practice , right ? Apollo-Roboto
