Testing contract
Expected to pass- Scenario
- Parse the file with a C# parser or language server and resolve its top-level declarations.
- Expected result
- It parses with no diagnostics: 115 bytes and 4 lines of C#, LF line endings, no BOM, containing a LINQ method chain. Round-tripping it through a formatter must not change the token stream.
What is a .cs file?
C# (.cs) is a plain-text source file for Microsoft's C# language: a statically typed, object-oriented language on .NET. It features classes, records, LINQ, async/await, and nullable reference types.
How to use this file
Use an example .cs file to test syntax highlighters, Roslyn-based analyzers, formatters (dotnet format), and language-detection tooling.
How to use this file for testing
“C# LINQ SAMPLE” is a deterministic Novus Examples fixture for Syntax highlighting, Code parsing, Editor testing. Idiomatic hello-world programs and realistic snippets across sixteen languages, exercising comments, string escapes, interpolation, numeric literals, and language keywords, for testing syntax highlighters, editor themes, and tree-sitter grammars.
Documented properties for this file: idiomatic sample · csharp · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.
This is a short, known-correct source file. Run it through your syntax highlighter, linter, formatter, tree-sitter grammar, or parser, and open it in the in-browser editor to tweak and re-download. Each snippet exercises comments, string escapes, literals, and language keywords.
