declare a vector of arrays or an array of arrays (Platform::Collections::Vector<Platform::Array<uint16>^>^)

Question

I need to declare a vector of arrays or an array of arrays in c++ but if I declare it in the following way:

Platform::Collections::Vector<Platform::Array<unsigned char>^>^ mVectorArray = ref new Platform::Collections::Vector<Platform::Array<unsigned char>^>();

But I get the following compiler error, and I don't know how to fix it:

1>C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\collection.h(508): error C2728: 'Platform::Array<__TArg,__dimension> ' : a native array cannot contain this type

Thank you!

Hello,

 

I think this issue
is caused by we can not use jagged array with Windows Runtime type in C++/CX.

Answer 2

Is there any other way to do that?

I've also tried with std::vector but other errors appeared.

Thank you

Answer 3

Hi,

Maybe you can try to use native point, and use a function to get the value.

Best regards,
Jesse
