Hi Martin, Thanks, you spotted the source of the problem. When I removed GetType() from around Int32, my solution works:
<snippet> from System import Array, Convert, Int32 pyList = [9, 7, 8, 4, 6, 3, 6, 8, 4, 1] toBeSorted = Array.CreateInstance(Int32, len(pyList)) for index, item in enumerate(pyList): toBeSorted.SetValue(item, index) Array.Sort(toBeSorted) </snippet> GetType() is a curious thing. It is an operator in VB.NET, which probably got into my snippet from copying the sample for Array.CreateInstance from the .NET SDK documentation somewhere. There wasn't any NameError while running the script though? In VB.NET, it returns the Type object for the specified type, so it should return the Type object for Int32 in this case. However, when I did this in my script: print GetType(Int32) print GetType the output was: IronPython.Objects.OpsReflectedType <built-in function GetType> Strange. Since it is an operator in VB, IP shouldn't even recognize it! Thanks again, Ray 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.
