How to generate a string from a Regular Expression?

I have a regular expression using which i need to generate its corresponding string token..

A regular expression can generate infinate strings. So, a single string token can't be generated to it. Do you want to find the strings that satisfies the Regular Expression from a list of strings?
Mention you requirement in detail.

Perhaps you mean to show the string representation of a regular expression in memory? The following code snippet shows how to print the internal regular expression as it was passed into the regex constructor. It prints the following:

[hH]ello\s+[wW]orld$

// output the internal regular expression
Regex re = new Regex(@"[hH]ello\s+[wW]orld$");
Debug.WriteLine(re.ToString());

i wasn't making a serious suggestion... i was attempting to demonstrate the futility of attempting it.

Nice one, I particularly like the Explain module (I don't really see the point in Genex... but hey, if that's the request ;-)

I think these answers are very valuable and all that for 50p ;-) ....but the q. has been abandoned since the start...

This question received ample coverage, multiple experts come to the same conclusion: "cannot be done" unless you have infinite time/space.
