C# Viewer

Paste C# source code to create a clean, line-numbered review view. The tool measures code, comment, and blank lines, detects line endings and long lines, and produces copy-ready output without sending code to a server.

How to use this developer tool

Paste source code into the input area.
Select the processing mode and adjust the numeric option.
Run the tool or keep auto-run enabled.
Review status, summary, interpretation, and the copy-ready output.
Copy the result or download it with the appropriate extension.

What this developer tool does

Input → protected lexical scan → tool-specific parsing or transformation → metrics → status and recommendations

Results are browser-side heuristics. They do not replace Roslyn, Clang, a compiler, unit tests, or project-specific static analysis.

Example

Input: Paste the included sample and run the tool.
Output: The page produces a real C# Viewer result, statistics, status, and practical interpretation.

Tips for better output

Use complete, consistently encoded source whenever possible.
Run compiler and project tests after automated formatting or conversion.
Macro-heavy, generated, or incomplete code may produce partial structural analysis.
Keep auto-run disabled when editing extremely large source files.

FAQ

How do I view C# code online?

Paste source into the input area, select the available options, and run C# Viewer. The result is processed locally in your browser.

How do I add line numbers to C# source code?

The tool reports browser-detectable structure and style signals with line-oriented output where applicable.

Can I inspect long lines in C# code?

The analysis is heuristic and intentionally avoids claiming compiler-level certainty.

How do I review C# source without an IDE?

Large or macro-heavy files may produce partial results; use a compiler or language-specific analyzer for final verification.

Does this C# Viewer upload my code?

Run the formatter or validator first, then review the generated recommendations and copy or download the output.
