C++ vector with managed objects

Question

Hello I need to have vector (or some other data structure, which is similar) filled with managed objects.

Usually I can write:

std::vector<Object> vect;

But I cannot use:

std::vector<Object^> vect;

Can somebody explain, how to change declaration or advice other structure instead of vector. Thanks.

Answer 1

Use .NET generic List class: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx

List enumeration sample from the same WEB page, as requested by user1237747's comment:

#include "stdafx.h"
using namespace System;
using namespace System::Collections::Generic;

int main(array<System::String ^> ^args)
{
    List<String^>^ dinosaurs = gcnew List<String^>();

    dinosaurs->Add("Tyrannosaurus");
    dinosaurs->Add("Amargasaurus");

    for each(String^ dinosaur in dinosaurs )
    {
        Console::WriteLine(dinosaur);
    }

    return 0;
}

Replace String^ with the type you need. You can also access List elements by index using [] operator.

Generally, avoid mixing managed and unmanaged types, if this is not absolutely necessary.

Answer 2

Yes, there are stl data structures for managed types. Below is an example using a vector (per your request).

#include <cliext/vector>

cliext::vector<Object^> vect;
