How do I check for type equality in IronPython?

I need the equivalent of the following C# code in IronPython:

if (x.GetType() == typeof(xType))

or

if (x is xType)

Answer 1

from System import *
if x.GetType() == Type.GetType(xType):

Answer 2

Say C is a static class, not fully qualified but imported into the iron python script x is an instance of C And ABC is the fully qualified name

Why don't these work?

x.GetType() == Type.GetType("A.B.C")

OR

x is Type.GetType("A.B.C")

OR

x is C

OR

x.GetType() == Type.GetType(C)
