What C# Parsers Exist for Source Code and Assemblies, and Which Are Recommended?

Comprehensive Guide to C# Code Parser

In the field of software engineering, code parsing plays a key role in extracting meaning and structure from source code. For C#, there are a range of parsers for different parsing needs. This article will take an in-depth look at the available options and their respective advantages, covering parsing from source code to assembly.

Source Code Parser

• CSParser: An open source parser that supports C# versions 1.0 to 2.0.
• Metaspec C# Parser: A commercial parser that supports C# versions 1.0 to 3.0.
• #recognize!: A commercial parser supporting C# versions 1.0 to 3.0.
• SharpDevelop Parser: Provides line and file information for parsed code.
• NRefactory: An open source parser with semantic analysis capabilities, supporting C# versions 1.0 to 4.0.
• C# Parser and CodeDOM: A commercial parser that supports C# 4.0 and includes C# 5.0 asynchronous capabilities.
• Microsoft Roslyn CTP: A "compiler as a service" that provides parsing capabilities.

Assembly parser

• System.Reflection: A built-in parser for interacting with assemblies.
• Microsoft Common Compiler Infrastructure (CCI): Open source parser used by Fxcop and Spec#.
• Mono.Cecil: An open source parser supporting C# versions 1.0 to 3.0.

Selection Considerations

When choosing a parser, consider the following factors: source code and assembly parsing, support for specific C# versions, and availability of line and file information. Also, keep in mind that assembly parsing provides limited line and file information compared to source code parsing.

Recommended

For comprehensive parsing of C# source code, Mono.Cecil and NRefactory are highly recommended. Mono.Cecil excels at assembly parsing, while NRefactory provides extended functionality with its semantic analysis capabilities.
