Object-Oriented Programming

Introduction Ever stared at a massive class file with hundreds of lines of code and thought, “What is this thing even supposed to do?” I sure have. That confusion usually points to problems with cohesion and coupling, two concepts that might sound academic but actually make the difference between code you want to work with and code you want to run away from. Let’s talk about these two fundamental ideas that can transform your code from a tangled mess into something you’re actually proud of. ...

Constructor Chaining in C# Ever written the same initialization code in multiple constructors? Constructor chaining is a neat trick in C# that lets you call one constructor from another in the same class. It’s a simple way to avoid repeating yourself and keep your initialization logic in one place. What’s Constructor Chaining All About? When you’re building a class in C#, you often need different ways to create objects. Maybe sometimes you have all the details, other times just the essential ones. ...

Introduction If you’ve ever been in a job interview for a software developer position, chances are you’ve been asked to explain the difference between DIP, DI, and IoC. I know I have, and the first time I was asked, I definitely stumbled through my answer! These three terms, Dependency Inversion Principle, Dependency Injection, and Inversion of Control, sound awfully similar and are often used interchangeably (incorrectly) by developers. But they’re actually distinct concepts that play different roles in helping us write better code. ...

Introduction If you’ve been coding for a while, you’ve probably heard of SOLID. It’s a set of five design principles that Robert C. Martin (better known as “Uncle Bob”) came up with back in the early 2000s. Since then, these ideas have become pretty much essential knowledge for anyone writing object-oriented code. But SOLID isn’t just another tech buzzword to memorize for interviews. These are practical ideas that actually help you write better code. I’ve found that following these principles helps me avoid creating those messy, brittle codebases that become a nightmare to change later on. ...

Introduction If you’ve spent any time building C# applications, you’ve probably run into situations where you need to decide whether your objects should be changeable or locked down after creation. This choice between mutability and immutability isn’t just academic, it can significantly impact how your code behaves, how easy it is to debug, and even how it performs. In this post, I’ll walk you through both approaches and help you figure out which one makes sense for your specific coding challenges. ...

Introduction to Object-Oriented Programming Ever wondered why most modern programming languages are object-oriented? It’s not just a trend; OOP completely changed how we think about building software. Object-Oriented Programming (or OOP, as we’ll call it) burst onto the scene in the 1990s and turned traditional programming on its head. Before OOP came along, most developers wrote procedural code, essentially a series of steps for the computer to follow, like a cooking recipe. While that worked for simpler programs, it became unwieldy as software grew more complex. ...

Introduction: Two Approaches to Global Access When building C# applications, we often need functionality that’s accessible from anywhere in our codebase. Two common approaches to this problem are static classes and the singleton pattern. While they might seem similar at first glance, they serve different purposes and come with their own strengths and trade-offs. In this post, I’ll walk through both approaches, show you real-world examples, and help you decide which one fits your specific needs. ...

So What’s an Abstract Class Anyway? Think of an abstract class as a half-finished blueprint. You can’t build directly from it, but it gives any derived classes a head start with some pre-defined structure and behavior. It’s like a parent saying, “Here’s how our family does some things, but you’ll need to figure out these other parts yourself.” Abstract classes sit right in the sweet spot between interfaces (all talk, no action) and concrete classes (fully ready to use). They’re perfect when you want to share code but still enforce certain implementation requirements. ...

Understanding Static Classes in C# A static class in C# is basically a container for methods and properties that don’t need any object to work. You can’t create instances of these classes, there’s no way to use the new keyword with them. Instead, you just call their methods directly through the class name. When Should You Use Static Classes? Static classes can really clean up your code when used correctly. Here are some situations where they make perfect sense: ...
