👨 About Me 👨
Hi, I’m Zoran. I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017, I have started publishing professional video courses at Pluralsight and Udemy, and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️

Zoran Horvat

A comprehensive guide to six core .NET collections: Array, List, Dictionary, Stack, Queue, and HashSet. Explains the performance characteristics, use cases, and trade-offs of each collection type. Covers when to choose arrays vs lists, proper usage of queues and stacks, and the benefits of dictionaries and hash sets for mapping and set operations. Includes practical examples like implementing undo-redo functionality with stacks and performance considerations for different operations.

The Ultimate .NET Collections Cheat Sheet

<p>I don’t know that I’d call it an “ultimate” cheat sheet, because it doesn’t go into detail on anything other than the core collections. To the video’s credit, it’s explicit about that fact within the first two minutes.</p>
<p>Maybe it’d be better called a basics cheat sheet.</p>
