📋 About This Course

This repository contains my implementations for Course 16 — OOP as it Should Be in C# from ProgrammingAdvices.com, taught by Dr. Mohammed Abu-Hadhoud.

Course 16 takes the solid OOP foundations built in C++ (Courses 10–11) and applies them fully in C# and .NET — teaching how to build clean, scalable, and professional systems using real object-oriented design principles in the language used in the industry.

📦 What's Inside

C# OOP implementations and exercises including:

• Class Design — Properties, constructors, encapsulation
• Inheritance — Base and derived classes, method overriding
• Interfaces & Abstraction — Designing contracts and abstract layers
• Generics — Type-safe reusable classes
• Collections — Working with Lists, Dictionaries, and custom collections
• C# OOP Patterns — Real-world patterns used in professional .NET development

Sample Code

class clsPerson
{
    public int Id { get; set; }
    public string? Name { get; set; }
    public int Age { get; set; }

    public clsPerson(int Id, string Name, int Age)
    {
        this.Id = Id;
        this.Name = Name;
        this.Age = Age;
    }
}
