Your code makes no sense. You allocate some unmanaged memory large enough to store the report bytes, but you never initialize it. You then pass an IntPtr to a method which expects a String containing the report path.

There doesn't seem to be a way to load a Crystal Reports file from an in-memory representation. You'll need to save the report to a temporary file, and load it from there.
