C# Code to generate strings that match a regex [closed]

Question

I use regular expressions to validate user input. Now I can configure the regex and so it would help the user to see an example of how a certaint input has to be formatted.

Is it possible to generate some strings that match an arbitrary regex? And is there even an implementation usable somewhere?

UPDATE: Due to the licence I can not use REX. Are there other possiblities?

Answer 1

Try using this app Rex can do this :)

For java it's https://code.google.com/p/xeger/

So there are many regex matches generators :)
