Problems compiling in visual studio 2015 after adapting with visual studio 2010. What should I do?

Question

visual studio

The project was written in visual studio 2010. I translated it into visual studio 2015, but problems started to arise. I got rid of almost all of them, but the problem with std::array remained.
The Form1.h file, as I understand it, is a file for the form designer.

Example::top_cornea = gcnew array<int>(bmp->Width);
 Example::bottom_cornea = gcnew array<int>(bmp->Width);
 Example::x1_width= gcnew array<int>(bmp->Width);
 Example::x2_width= gcnew array<int>(bmp->Width);
 Example::width_cornea= gcnew array<int>(bmp->Width);

It writes errors:
1. A type specifier is required
2. Not enough arguments for the std::array class template
I searched the Internet, found such an option, but the errors do not disappear.

Example::top_cornea = gcnew array<int, (bmp->Width)>;
 Example::bottom_cornea = gcnew array<int, (bmp->Width)>;
 Example::x1_width= gcnew array<int, (bmp->Width)>;
 Example::x2_width= gcnew array<int, (bmp->Width)>;
 Example::width_cornea= gcnew array<int, (bmp->Width)>;

I've been digging for the second day already, I would have already redid this form, but the code is not mine, I'm afraid to dig even more.

Answer 1

Looks like using namespace std was added somewhere, causing array to be recognized as std::array instead of cli::array
Either remove using namespace std or explicitly specify cli wherever needed:
gcnew cli::array(...

Answer 2

std::array is created on the stack as a regular sish array and requires the size to be specified at compile time, something like this: std::array<int, 3> array = {1, 2, 3};
Edit: Perhaps something else is needed there, but somewhere using namespace std
Edit is used: Didn't get into the second part right away. The template parameter must be known at compile time, i.e. bmp->Width must be constexpr or statc constexpr with the appropriate referencing syntax. Dynamic arrays in C++ are std::vector, you most likely used array from CLI, but I don't understand CLI.
