How to Use Extension Methods in C# with Examples

🚀 10 Essential C# Fixes That Will Make You a Better Programmer 💻 Many developers unknowingly write C# code that’s inefficient or hard to maintain. In my latest article on CSharpCorner , I’ve shared 10 common mistakes and practical fixes to help you write cleaner, faster, and more maintainable code. Here’s a sneak peek: ✅ Avoid magic strings & numbers ✅ Stop using empty catch blocks ✅ Simplify overly complex conditions ✅ Replace async void with async Task …and more best practices you can apply today!

What is a Class in C#? Everything begins with one essential concept — the Class. In C#, a Class is the foundation of Object-Oriented Programming. It acts as a blueprint that defines how your digital world behaves. It describes what an object has (its properties) and what it does (its methods). Think of it like this: the Class defines the structure, and the Object is the instance created from it. Each object carries its own unique data and behavior, but all follow the same design defined by the class. Classes make your code organized, reusable, and easier to maintain. They enable inheritance and polymorphism — two key principles that make software modular and scalable. In short, Classes are the backbone of C#. They transform ideas into code, and code into something real. #CSharp #CSharpProgramming #DotNet #ObjectOrientedProgramming #OOP #SoftwareDevelopment #ProgrammingConcepts #LearnToCode #CodingJourney #4brio #TechEducation

💡 C vs C++ — Understanding the Core Difference As developers, we often start our journey with C, the foundation of modern programming — a procedural language focused on functions and structured logic. Then we move to C++, an evolution that introduces Object-Oriented Programming (OOP) — bringing classes, objects, and reusability into play. Both languages are powerful in their own way: ✅ C – Fast, low-level, close to hardware ✅ C++ – Flexible, modular, and object-oriented Understanding their differences helps us appreciate how programming has evolved — from procedural thinking to object-oriented design. 🚀 #C #CPlusPlus #Programming #Developers #Coding #Learning #SoftwareDevelopment #OOP #TechEducation

🧵 Comparing C# and Go programming languages: classes, structures, methods and where they live In previous posts (https://lnkd.in/eqK5dduM) we have taken a look at variable declaration in C# and Go and their differences. As last time, it won’t be a detailed review of the languages — just simple words and definitions. 📦 Now it’s time to discover how different objects work in C# and Go. 👇 In the image below you can see the difference of types declaration that wonderful languages. 🔄 As in the previous topic, the syntax and philosophy are very different — but they serve the same purpose. The next topic are going to consider abstractions and inheritance. 🙏 Thanks for reading, and have a nice day! #GO #CSharp #backend #ProgrammingLanguages #programming

Delphi/Object Pascal's new position is 8th, which was 11th in 2016, with 2.06% market share and a +0.58% rating increase, a stronger increase than many mainstream languages. This indicates a continued momentum in the desktop, embedded and enterprise niches where a strong type system, fast RAD GUI tooling and very long-lived code bases matter, and while Python remains the top language and C/C++ continue to dominate systems programming work, Object Pascal's continued growth suggests renewed investment, modern frameworks and active maintenance of legacy applications. Therefore, for teams seeking stability, native performance and productive RAD workflows, Pascal may be increasingly considered a pragmatic choice to mainstream languages.

🚀 Final chapter of my LINQ series is out! After exploring IEnumerable, yield return, and unit testing, it’s time to put everything together by building our own LINQ methods from scratch. In this article, I share how I used this project to teach my team that LINQ isn’t “magic”, it’s just clean, powerful C# code. We implement .Where() and .Any() step by step, using everything we’ve learned so far. 👉 Read here: https://lnkd.in/dSS6FHq9 #dotnet #csharp #linq #learning #programming #developers #teamlead

Are you interested in learning CSharp? I've created a course to take you from zero coding experience through to understanding the basics of writing code in C#. This 5 hour course gives you a short primer on what programming is and what tools you need to get started writing C#. From there, I jump into examples that you can follow along with to help reinforce the learning as you go through the course. No previous experience required! And if you know some other languages already, this is still a great opportunity to get into C#. #DotNet #CSharp #LearnToCode #Coding #Programming

🚀 C vs C++ — One of the most important comparisons every programmer should know! Many beginners get confused between these two languages, but understanding their core difference helps you decide which one to learn first and how both shape your programming fundamentals. ✔️ C = Procedural (step-by-step logic) ✔️ C++ = Object-Oriented (real-world modelling with classes & objects) This chart explains all the key differences — from polymorphism to inheritance to approach style. A must-know topic for anyone starting their programming journey! 💡👨💻 #CProgramming #CPP #ProgrammingBasics #SoftwareEngineering #CodingJourney #LearnToCode #TechCommunity #DeveloperLife #CodeNewbie #ProgrammingConcepts #ComputerScience #BuildInPublic #WebDevelopment

Recently, I came across an interesting feature introduced in 𝗖# 𝟴.𝟬 — the ability to 𝗽𝗿𝗼𝘃𝗶𝗱𝗲 𝗱𝗲𝗳𝗮𝘂𝗹𝘁 𝗺𝗲𝘁𝗵𝗼𝗱 𝗶𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻𝘀 inside interfaces. Traditionally, interfaces in C# could only 𝗱𝗲𝗳𝗶𝗻𝗲 𝗺𝗲𝘁𝗵𝗼𝗱 𝘀𝗶𝗴𝗻𝗮𝘁𝘂𝗿𝗲𝘀, and every class had to provide its own implementation.  Now, we can define 𝗱𝗲𝗳𝗮𝘂𝗹𝘁 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝗿 𝗱𝗶𝗿𝗲𝗰𝘁𝗹𝘆 𝗶𝗻𝘀𝗶𝗱𝗲 𝘁𝗵𝗲 𝗶𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲, making it easier to evolve codebases without breaking existing implementations. If a class doesn’t override the method, it simply uses the default implementation.  If it does override, the class’s version takes precedence. #CSharp #DotNet #SoftwareDevelopment #Learning #Programming #CodeTips

Today I solved the Range Addition II problem using the 2D Difference Matrix + Prefix Sum technique. This approach reduces each query from O(n²) → O(1) using boundary marking, followed by prefix propagation. It helped me get a clean 10 ms runtime (Beats 85%) on LeetCode! What I learned: Efficient 2D range updates using difference matrices How prefix sums can rebuild cumulative effects How to avoid repetitive computation inside loops Writing clean and optimal Java for competitive programming Key insight: Instead of updating every single cell in each query, update only the entry and exit boundaries, then use prefix sums to expand the changes across rows and columns. A small trick — but a huge performance boost. Proud of the progress. On to the next challenge! #leetcode #javaprogramming #interviewprep #codingchallenge #dsa #learningeveryday #programming
