Incompatibility using managed array and std:array at same time

Question

I have my C++/CLI code using arrays like this (for example):

array^ GetColNames() { 
    vector vec = impl->getColNames();
           


        

Answer 1

Clearly you have a using namespace std; in scope somewhere. Watch out for it being used in .h file if you cannot find it.

You can resolve the ambiguity, the C++/CLI extension keywords like array are in the cli namespace. This compiles fine:

#include "stdafx.h"
#include <array>

using namespace std;         // <=== Uh-oh
using namespace System;

int main(cli::array<System::String ^> ^args)
{
    auto arr = gcnew cli::array<String^>(42);
    return 0;
}
