Is there a tool that generates P/Invoke signatures

Question

I stumbled upon a tool that generates P/Invoke signatures for Microsoft's own unmanaged DLLs: PInvoke Interop Assistant

Is there a similar tool that will generate P/Invoke signatures for third-party unmanaged DLLs?

Alternately, any way to feed a third-party DLL to PInvoke Interop Assistant

EDIT: Actual issue I am trying to resolve

Answer 1

You can create C# wrapper for any native DLL including both C-style DLL exporting functions and C++ DLL exporting classes by using xInterop C++ .NET Bridge with .NET to Native C++ Bridge. It is available for free evaluation with some limitations.

Google quickly found http://www.pinvoker.com/ (Compatiblity listed as VS2005, 2008, and 2010; it doesn't seem to have been updated to work with newer versions)

Microsoft's C++/CLI compiler can also do this, if you use /clr:safe and #include the header file, it will generate p/invoke code which you can extract with e.g. ILSpy (free) or Red Gate Reflector (used to be free).

This project is active and looks promising for the task: https://github.com/mono/CppSharp

Answer 4

I use PInvoke Interop Assistant for unmanaged DLLs by using the third tab in the UI, marked "SigImp Translate Snippet". Simply copy-and-paste your header into the "Native Code Snippet" window and press Generate (or turn on Auto Generate). As an illustration here's some code from a question of mine. Note that for some reason errors don't appear in the Error panel but as comments at the top of the generated code.

As several people have already said, the generated code should be used as a guide - you may well have to make changes to get exactly what you want.

Use Dumpbin.exe that comes with the VS SDK, Dumpbin, you'll still need to write the pinvoke signatures manually from the dumped data
