C# call c++ method with string parameter from wrapped class

Question

I am trying to call a method of a c++ class that uses a string parameter but I have this error

Error CS0570 'Wrapper.write(int, ?)' is not supported by the language

Basically I have this code, and it works with other simple methods without string object

I read this but as they are not static methods I can't use it

Any idea?

In C#

Wrapper tb = new Lib.Wrapper();
tb.write( 1, "tablas.txt");

In C++ Lib.h

private:
     myCppClass* pMyCppClass;
public:
     Wrapper();
     int write(int id, String^ file);

And C++ Lib.cpp

int Lib::Wrapper::write(int id, String^ file)
{
     std::string aux= marshal_as < std::string > (file);    
     return pMyCppClass->write(id, aux);
}

Yes, it is a manage c++ wrapping a unmaneged c++ class (myCppClass) — jgrdpy, Jun 13 '16 at 14:47
Can you give source C++ Lib? I tryed create it situation but all work fine for manage C++. — askeet, Jun 13 '16 at 14:52
I figured out the libraries wasn't updating so I delete the dll, clean the solution, recompile and add again the reference in C# and it works — jgrdpy, Jun 13 '16 at 15:07
