C# DllImport library written on C++

Question

I\'m pretty new in C#. I have Dll written on C++ by myself and I\'m going to use functions from that dll in C# app.

So, I do the following when declare functions in

Answer 1

public static __declspec(dllexport) int captureCamera(int& captureId);

is that method? If it is function, it cannot be static, as static and dllexport are mutually exclusive.

And the name is mangled. See http://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B_Name_Mangling. If you can get the mangled name, and then provide the DllImport with it (EntryPoint=MANGLED_NAME), it should work.

You can provide linker with .def file, containing definition of exported functions, and their names aren't mangled then:

Project.def:

EXPORTS
    captureCamera @1
