Thank you!!

This is the second thread where I've cleaned up virtually the same code. Please don't post code containing great wads of whitespace and also please make sure that your braces are aligned. There's no reason to post code that inherently makes it hard for us to read it.

Ok
No great wads of whitespace the next time

you can use Regular Expression to extract all the words to to a list, say wordsList, then use Distinct() extension to get only distinct words
eg distinctWords().Distinct()
