And if anyone is wondering, the set would be:

foo.set_Item(0, "World")

Good Call. foo.get_Item() works great.  foo[0] throws an exception.

Thanks Justin!  That's much better than ToArray.GetValue...

I can't figure out how to get items out of any of the CLR List types in IronRuby.  Here's a contrived example:

>>> require 'mscorlib'
=> true
>>> foo = System::Collections:: ArrayList.new()
=> #<ArrayList:0x0000056>
>>> foo.Item(0)
System.MissingMethodException: undefined local variable or method `Item' for #<ArrayList:0x0000056>:ArrayList

The actualy method name will be get_Item(), I think. But did you try

>>> foo[0]

Might work!
