Question

I want to declare an array of handel as the following code:

using namespace System::Drawing;
ref class B 
{
    Bitmap^ b[];

    B()
    {
        b = new Bitmap^[10];
    }
};

But it threw error when compiling

error C2728: 'System::Drawing::Bitmap ^' : a native array cannot contain this managed type
error C4368: cannot define 'b' as a member of managed 'B': mixed types are not supported
error C2728: 'System::Drawing::Bitmap ^' : a native array cannot contain this managed type
error C2440: '=' : cannot convert from 'System::Drawing::Bitmap ^*' to 'System::Drawing::Bitmap ^[]'

Someone can tell me the correctly way to declare an array of handel?

Many thanks!

You need to use gcnew since this a .Net array, not a C++ array since this is an array of a managed type, not an array of a native type. I don’t have a compiler handy to test this code, but I believe this would be the way to do it.

using namespace System::Drawing;
ref class B 
{
private:
    array<Bitmap^>^ b;

public:
    B()
    {
        b = gcnew array<Bitmap^>(10);
    }
};
