About C# by Examples

What Is This Site?

C# by Examples is a free, open educational resource that provides practical, ready-to-run C# code snippets for developers at every level — from beginners picking up their first language to experienced engineers who need a quick reference.

Every example on this site is written to be clear, concise, and immediately copyable. No fluff, no lengthy preambles — just working code with enough context to understand what it does and why.

What You Will Find Here

• Idiomatic C# patterns covering strings, collections, LINQ, async/await, and more
• Side-by-side comparisons (e.g., struct vs class, List vs Array)
• Practical examples for everyday tasks such as reading files, formatting dates, and handling nulls
• A growing library of 60+ topics, organized by tag for easy discovery
• A built-in Regex Tester for C# regular expressions

Our Goal

The goal is simple: help C# developers solve problems faster. Whether you search for “how to iterate a dictionary in C#” or “difference between const and readonly”, we want the answer to be here — correct, modern, and easy to understand.

All content targets modern C# (C# 10+) and .NET 6+ unless otherwise noted.
