C# Formatter — Reindent C# Code with Allman Brace Style

Reindent only — not a full formatter

Reindent C# source with Allman braces, auto-property normalization, and expression-bodied member tidy-up. Indentation tidy, not a full Roslyn format.

How to use

  1. 1 Paste C# source code.
  2. 2 Pick brace style (Allman default for C#) and indent size.
  3. 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. 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.

What is C# Formatter?

A C# Formatter is a tool that reindents C# source code in the browser using Allman braces, with auto-property normalization and expression-bodied member tidy-up. It works as an indentation tidier rather than a full Roslyn-based formatter, applying consistent layout to code while keeping the source on the user's device.

Features

Allman-style reindent

Re-indents by nesting and places braces on their own line, the .NET convention (K&R also available).

Accessor & => tidy

Normalizes `{ get; set; }` spacing and expression-bodied member arrows.

100% private

Runs client-side — your C# is never uploaded.

Example

Input

public class A {
int X{get;set;}
}

Output

public class A
{
    int X{ get; set; }
}

Common use cases

  1. 1

    Fix pasted C#

    Repair indentation on a snippet from a log, gist, or forum.

  2. 2

    Apply Allman style

    Normalize brace placement to the standard .NET convention.

  3. 3

    Tidy before commit

    Clean up layout without running a full dotnet-format pass.

Summary

Zerethon's C# formatter reindents C# source in your browser by brace depth, defaulting to the Allman brace style common in .NET, and normalizes auto-property accessors (`{ get; set; }`) and expression-bodied `=>` spacing. It is a lightweight reindenter, not a full dotnet-format — it tidies layout without a full rewrite. Nothing is uploaded.
