Copy from const char* to a byte array C++/c# interop Marshal::Copy

Question

I\'m trying to send an image from C++ to C# with an interop (marshaling) of C++ managed. image->getStream() return a const char* from a string.<

Answer 1

I wouldn't use Marshal::Copy. Since you have the array locally, why not just pin it and use memcpy?

pin_ptr ptrBuffer = &byteArray[byteArray->GetLowerBound(0)];

You can now call memcpy to ptrBuffer.

When the scope ends the pinning is automatically undone.
