Can't print String in console

Question

I am getting this error when I try to print

Error C3867 'Carta::mostrar': non-standard syntax; use '&' to create a pointer to member

Carta.h

using namespace System;
    ref class Carta
    {
    private:
         String^ cara;
         String^ palo;

    public:
         Carta();
         Carta(String^ pCara, String^ pPalo);
         String^ mostrar();
    };

main.cpp

#include "Carta.h"
#include <stdio.h>

using namespace System;
using namespace System::Windows::Forms;

[STAThread]
int main(array<String^>^ args) {

    Carta^ nueva = gcnew Carta("1", "Diamantes");
    Console::WriteLine(nueva->mostrar); //Error here
}

Answer 1

Console::WriteLine(nueva->mostrar); //Error here

You are trying to access a member of nueva object instead to call a method of this object. mostrar is a method, not a property. Try to change to:

Console::WriteLine(nueva->mostrar());
