Hi Ray, Fredrik already asnwered your generator expression related question. As for the arrays, Here is solution that seems to work:
>>> from System import * >>> a = Array.CreateInstance(Int32, 10) >>> a System.Int32[](0, 0, 0, 0, 0, 0, 0, 0, 0, 0) >>> r = range(10) >>> for i in r: a[i] = i >>> a System.Int32[](0, 1, 2, 3, 4, 5, 6, 7, 8, 9) I tried your code snippet, but couldn't identify what the GetType function was. I hope this helps. Again, it is not a perfect solution and it is one of many items on our to-do list to make Python built-in types and .Net types play better together.
