[IronPython] Type.GetType returns None

Those aren't comparable statements.  If you had passed "String" (in quotes) in your C# I think that would have worked, but "string" should not -- the Type.GetType(string) overload is defined as a case-sensitive search, and in general wants an "assembly qualified name".


Perhaps all would be fine in pure IP if you had just used Type.GetType(String) or String.GetType(); I'm away and not easily able to try it myself.

I would guess that the cause is that Python's "string" type (lowercase without the quotes) is not the same as .Net's "String" type (mixed case without quotes).
