Run NQueryViewer and paste the following query:

SELECT  ''.Split('-'.ToCharArray(), 10)

Then type a . at the end to get the list of available properties and methods on the string[] type. It fails with the following exception:

Reason: There is a method named Get in the string[] (Array) type, which accepts a single int32 parameter and said parameter does not have a name.
