C# Formatting Tips

  • Use consistent brace style — Allman (new line) or K&R (same line) throughout your project.
  • Keep one statement per line for easier debugging and code review.
  • Use var only when the type is obvious from the right-hand side of the assignment.

Frequently Asked Questions

Common questions about Csharp Formatter formatting answered

Yes, our C# formatter is completely free with no registration required. All processing happens in your browser.

Yes, our formatter supports modern C# features including records, pattern matching, nullable reference types, and top-level statements.

Yes, you can choose between Allman style (braces on new lines) or K&R style (opening brace on same line) to match your team conventions.

No. The formatter only adjusts whitespace, indentation, and spacing. It never modifies identifiers, types, or logic.

Yes, the formatter properly handles LINQ query expressions, lambda expressions, and method chains with consistent formatting.

The .NET runtime (dotnet/runtime) engineering guidelines: 4-space indent, Allman braces (opening brace on its own line) - the style of the .NET reference source and what Visual Studio and Rider both default to for C#. K&R style is available as an option for Unity and game-studio codebases, which commonly use it.

Method chains keep one call per line when wrapping (items.Where(...).Select(...).ToList()), aligned on the dot; query syntax (from x in xs where ... select x) breaks one clause per line. Both are preserved as written - converting between query and method syntax is a semantic refactor, not formatting.

Preprocessor directives (#if DEBUG) keep their position relative to the code they gate and are never re-indented to match surrounding code (the compiler treats them as line-anchored). File-scoped namespaces (namespace App; - C# 10+) are left as-is rather than expanded to block form, since converting back and forth changes the file's brace balance.
