C# Formatter
Reformat C# source with Allman braces, auto-property normalization, and expression-bodied member tidy-up.
How to use
- 1 Paste C# source code.
- 2 Pick brace style (Allman default for C#) and indent size.
- 3 Toggle auto-property normalization to tidy <code class="rounded bg-slate-100 px-1 text-xs dark:bg-slate-800">{get;set;}</code> blocks.
- 4 Copy or download the result.
Why use this tool
- Defaults match the Microsoft / Visual Studio style: Allman braces, 4-space indent.
- Tidies common shorthand: auto-properties and expression-bodied members.
- Pure client-side — your code never leaves the browser.
- For full Roslyn-level format use <code class="rounded bg-slate-100 px-1 text-xs dark:bg-slate-800">dotnet format</code> locally.
Frequently asked questions
Does this match the dotnet format CLI?
Close on braces and indent — but the CLI also reorders usings, applies analyzers, and rewrites expressions. Use dotnet format for canonical output.
Will it touch LINQ chains?
LINQ statements are reindented if they break across lines but never rewritten. Method-chain layout is preserved.
Looking for a Java formatter?
Yes — see our <a href="/java-formatter" class="underline">Java Formatter</a> which uses the same engine with K&R default.
