Export dll method from C++ to C#. Why I need: “ extern ”C“ ”

Question

In my dll there is a method that I want to export.

//Works:

extern \"C\" __declspec(dllexport)

//Wont work

__declsp         


        

Answer 1

The compiler normally decorates your exported names to include information about class and signature. extern "C" tells the compiler not to do that.
