CppSharp is a tool and set of libraries which facilitates the usage of native C/C++ code with the .NET ecosystem.

It consumes C/C++ header and library files and generates the necessary glue code to surface the native API as a managed API. Such an API can be used to consume an existing native library in your managed code or add managed scripting support to a native codebase.

The supported target languages at present are C# and C++/CLI.

It can also be used as a library to parse native code into a syntax tree with a rich declaration and type information model.

Libraries

AST

Mirrors the Clang's C/C++ AST and type system classes in C# APIs.

Check out Clang's AST introduction docs for more details about its architecture.

  • C++ declarations
  • C++ statements / expressions
  • C++ types
  • Class object layout
  • Declaration visitors
  • Type visitors

Parser

Provides APIs for parsing of C/C++ source code into a syntax tree.

  • Parsing of C/C++ source code
  • Parsing of libraries archives symbols
  • Parsing of shared libraries symbols
  • Based on the very accurate Clang C++ parser.

Generator

Generates the glue binding code from a syntax tree of the native code.

  • Multiple backends: C++/CLI and C# (P/Invoke)
  • Multiple ABIs: Itanium, MS, ARM, iOS
  • Multiple platforms: Windows, OS X and Linux
  • Multiple runtimes: .NET and Mono
  • C++ virtual methods overriding from managed code
  • C++ multiple inheritance by translating to C# interfaces
  • C++ std::string
  • C++ default parameter values
  • C/C++ semantic comments (Doxygen) to C# comments
  • Extensible bindings semantics via user passes and type mapping
