This repository demonstrates the difference between traditional switch statements and modern switch expressions introduced in C# 8.
The goal is to show how modern C# encourages writing clearer, more expressive decision logic, rather than just reducing lines of code.
Switch expressions were introduced back in C# 8, yet many codebases still rely heavily on verbose switch statements.
With C# evolving rapidly (we’re already discussing C# 14), it’s important to not just learn new features — but to adopt better ways of expressing intent.
Switch expressions don’t just reduce lines of code — they improve how we think about decision logic.
- Traditional switch statements
- Modern switch expressions
- Same business logic implemented both ways
- Clear comparison focused on readability and intent
-
✅ Switch expressions
When your logic returns a value and can be expressed declaratively. -
✅ Switch statements
When your logic performs multiple actions or side effects.
- .NET SDK
- C# 8 or later
