An aside that may be useful: .net will skip array bounds checking within simple for-loops, as an optimization. But only if the binaries have all their optimizations turned on. A binary built for debug has them turned off. There is a huge speed up for iterating over an array when these optimizations are used. So make sure you are not looking at a compiler optimization configuration problem.

I need to copy a .NET Array (e.g. Double[] or Byte[]) to a numpy array, but it seems the only way to do so is element by element, which is very slow. Since we are copying a lot of data in real time, it creates a real bottleneck.
Alternatively, efficient conversion of the .NET array to a Python style byte string would allow numpy.fromstring() to be used for creating the numpy array.
(I see a similar question went unanswered on the list in August 2011, but I was hoping someone may have figured it out by now.)
