Re: [Swig-user] Generating CSharp wrappers

[David P. <dpi...@me...>]

My C++ DLL also contains C-mangled names, and my C# wrapper also does not include the prefix "_" and suffix "@d", but somehow it works anyway. I guess the CLR tries "_Name@d" if it can't find "Name" itself. Perhaps something else is wrong.
