Use C# data from a C++ DLL

[Fabry]

Dear all,

I do not know if this is the right group for my questions but I would
guess.

I have some DLL written in ANSI C++ for a cross platform use. For each
DLL I have a Plugin class that extend an interface tha allow me to
load the internal functionality of the DLL. Now I would like to use my
DLLs in a C# application.

The big problem is that my C++ routines have different data structure
as argument. The data structures are complex and use char, int,
double, char* and so on...

How can I wrap my plugins for the use of the data structures? There is
any trick for my purposes?

Thank you in advance for the help.

Best Regards,
Fabrizio

Fabrizio,

One solution is to design an idealised C# interface to your DLL but
implement it in C++/CLI in your C++ project. You can then use C++/CLI
to interface seamlessly with your native C++ code.
