[IronPython] [Bug] Arrays are stripped of .NET methods / properties

[Dino Viehland]

This one is definite a bug - all the methods on array should always be visible.  I've created work item 11971 for the issue (http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=11971).  I've tentatively lumped it in 1.1.1 but having not looked at the issue I don't know how invasive the fix will be - but I suspect it will be fairly simple.

Hello all,

A bug in IronPython 1.1. This one has bitten us and it would be very
nice to have it fixed.

Create a .NET array in one module and then use it in another module that
hasn't imported clr (or System) and it will be stripped of its .NET
methods and properties.

Importing clr fixes the problem, but shouldn't be necessary (right?).

To see this, create a module called 'createArray.py':

from System import Array

def CreateArray():
    return Array.CreateInstance(int, 2, 2)


Then use the module from another IronPython program. E.g. :

from createArray import CreateArray

array = CreateArray()
print array.Rank

This results in the following error:

C:\>ipy testArray.py
Traceback (most recent call last):
  File C:\testArray.py, line 4, in Initialize
AttributeError: 'Array[int]' object has no attribute 'Rank'

If you add an import clr to the program then it does the right thing...
