At Leoxia , we love to dive into practical performance topics that impact real-world development. This first post is a trial balloon—simple and concrete. And what better way to start than by benchmarking how we write conditions in C#?
🧪 What did we test?
We compared five common ways to structure condition logic in C#:
Classicif/else
Nested ternary operators
switchstatements
Pattern matching with types
Pre-computed array indexing
⚙️ Tools & Setup
Framework : .NET 8
Benchmarking : BenchmarkDotNet
Code available on GitHub : github.com/leoxialtd
📊 Results Summary
Each method has strengths and trade-offs. While array indexingmay seem unnatural in some cases, it turns out to be incredibly fast—especially when used for lookup scenarios rather than control flow. But beware: performance can shift depending on the complexity and size of your condition set.
