Generics in C#: Flexibility, Reusability, and Type Safety

stp2y0 CommentsNewscoding, collections, community, csharp, development, engineering, generics, inclusive, software

Meta Description:Learn how generics in C# enhance flexibility, reusability, and type safety in your code. Explore their role in collections, algorithms, and scalable application design. 1. What Are Generics? Generics allow developers to define classes, methods, and interfaces with placeholders for the type of data they will operate on. This placeholder, called a type parameter, is replaced with a specific type at runtime or compile-time. 2. Why Are Generics Necessary? Generalized Algorithms: Some algorithms, like sorting, are independent of the type of data. For example, you can sort integers, cars, or apples as long as they are comparable. Type Safety:…

Adding Revision Support to Entities in Entity Framework Core

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, efcore, engineering, entityframeworkcore, inclusive, software

Introduction As applications evolve, the need to track historical data or version control often arises. In this article, we’ll refactor an existing entity to support revisions using Entity Framework Core, allowing us to maintain a history of changes without duplicating the data model or introducing unnecessary complexity. We’ll walk through a step-by-step approach to transition a simple Document entity into a revisioned model. This method uses a discriminator to track multiple versions of the same document, with all revisions stored in the same database table. This approach is both flexible and scalable, making it easy to apply to other entities…

Introduction Learn how to get started with file globbing by creating a console project to list all Visual Studio solutions (.sln) under a specific folder along with project names for the solution exported to a json file. The reason for using solution and project files is that every reader here using Microsoft Visual Studio should have at least two while if the example were for Word documents or specific image types the code presented may not work so well. Other opportunities besides using a conventual console project there are commandline dotnet tools C# .NET Tools with System.CommandLine which the code…

Conditional application of chained LINQ queries

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, engineering, inclusive, programming, software

I write C# and I'm a big fan of using LINQ to create nice, readable chains of operations to filter and transform data in a functional style. int HighestEvenNumber(IEnumerable<int> numbers) => numbers .Where(x => x % 2 == 0) .OrderByDescending(x => x) .FirstOrDefault(); Enter fullscreen mode Exit fullscreen mode Sometimes though, there are conditions where parts of the chain should be included or omitted, but breaking the chain to add an if-statement feels wrong and disruptive. Let's say our previous example should throw an exception if there are no even numbers in the sequence instead of returning the default int…

Meta Description:Learn how to use tuples in C# for grouping elements, returning multiple values, and enhancing code readability. Explore examples, key differences from anonymous types, and hands-on assignments at easy, medium, and difficult levels Understanding Tuples in C#: A Better Way to Group Elements Welcome to a deeper dive into a powerful language feature in C#: tuples. While anonymous types are useful for grouping data, tuples offer a more flexible way to organize and access multiple values together across your application. Let's explore tuples and see how they differ from anonymous types. What Are Tuples? Tuples have been around in…

I developed an application that saves a backup every time a file on the desktop folder is saved, so I would like to release it to you in the hope that it will be useful to you. https://drive.google.com/file/d/1Z_G7TtBs1T5cRITIteauW7UcLeB5NDUL/view?usp=sharing This is a Windows application that automatically saves file backups. It saves backups of all files on the desktop completely automatically, without any operation. No operation is required other than having it running. It must be running. It can be fully automated by registering it as a startup application when the PC starts up. A "Desktop_BackUP" folder is created at the same…

Understanding SOLID Principles in C#

stp2y0 CommentsNewscoding, community, csharp, development, engineering, inclusive, learning, software, softwaredevelopment, tutorial

As developers, we often come across the term "SOLID" principles, which are a set of five design principles that help us write maintainable, scalable, and efficient code. However, understanding and applying these concepts in real-life projects can sometimes be tricky. To make it simpler, let's break down each principle with practical, relatable examples and code snippets that any developer can understand. 1. Single Responsibility Principle (SRP) Real-Life Example: Imagine you’re organizing a community event, and Alex, your friend, tries to handle everything—from setting up the venue, to promoting the event, to managing food. With so many responsibilities, things often slip…

c# Best Practice: Writing Code That Humans Can Understand

stp2y0 CommentsNewscleancoding, coding, community, csharp, development, engineering, inclusive, software

Introduction:Many programmers can write code that works, but good programmers write code that is easy for humans to understand. Reflect on the last time you had to maintain someone else's code. How many times have you felt the urge to throw it all away and start from scratch? Such situations arise when the code is not clean. But what does it mean for code to be clean? Clean code is easy to read, maintain, extend, and modify by any developer, not just the original author. In this article, we’ll explore the importance of clean code, share practical examples of principles…
