DLL import

Question

I have a c++ code and it has some operator overload methods like operator ()
As far as I know () operator can not be used in C# directly (or indirectly).
Is it possible to import such a dll writen in C++ to C#? Can I still use () operator in C# if it is possible?
Example in C++:

const MyClass MyClass::operator()(...) const {
...
  }
