What is the negation of the test "is"?

Question

To test if an object is of a certain type then we write if ( myObject is SomeClassName )

But how do we write if I want to test that the object is not of the mentionned type ?

`if (! myObject is SomeClassName)` ? – Gilad Green Oct 27 '18 at 19:22 — Gilad Green, Oct 27 '18 at 19:22

There isn't one, you have to wrap it in a ! operator:

if (!(myObject is SomeClassName))

if (!(myObject is SomeClassName))

Is probably the cleanest way of checking not is. Just checks if it is the type of object then flips it.
