Array of handles is not allowed C++

I'm having a issue translating a array of String^ that I'm receiving from a C# application. Why can I not create an array of String^? I'm fairly new to C++ so any help is appreciated.

public ref class Example
    {
        public:
            String^ Convert(String^ pointNames[], String^ outputPath)
            {

                std::string convertedPath = msclr::interop::marshal_as< std::string >(outputPath);
                std::string result = otherFunction(pointNames, convertedPath);

                return  msclr::interop::marshal_as< String^ >(result);
            }
    };

pointsNames[] is underlined as the error, with the message: Array of handles is not allowed.

What would be a better approach to send an array of strings from a C# application to C++?
