howto create a multidimensional Array of floats with Pythonnet

Question

I'm using pythonnet (http://pythonnet.sf.net) to bind together a python framework and a .NET library (I know if IronPython but this is not the question).

Using pythonnet, I can create an Array of floats, and initialize it from a sequence of values:

>>> from System import *
>>> Array[float]([1., 2.])
<System.Double[] object at 0x8a6c46c>

I need to pass an 3x3 array of floats to a method in the the .NET library, and I can't figure out how to create this.

Use Array.CreateInstance:

>>> a = Array.CreateInstance(Double, 3, 3)

That would create an empty 3x3 array though. How do you assign existing array values to the array?
