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)
System.Int32(0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
>>> r = range(10)
>>> for i in r: a[i] = i
System.Int32(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
I tried your code snippet, but couldn't identify what the GetType
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.
