Generate all Permutations of text from a regex pattern in C#

Question

So i have a regex pattern, and I want to generate all the text permutations that would be allowed from that pattern.

Example:

var pattern = \"^My (?:         


        

Answer 1

One method that might be a bit weird would be to put the possible choices into an array first, and then generate the regex based on the array and then use the same array to generate the permutations.
