Can a regex consist of child patterns (not value) in some variables so for example if I have following regex:-

"\d+X\d+" which can capture values like 7X4, is it possible to assign \d+ in some sort of variable and specify that variable in place of second \d+. Note that I am not talking about back-reference which will match the captured value rather than the pattern.

You are most likely looking for subroutines. – Jan Nov 11 '16 at 08:22
C# regex does not support recursion. You can build the pattern dynamically. – Wiktor Stribiżew Nov 11 '16 at 08:40
It seems so but I think subroutines are not available in C# which I am using. Thanks for the suggestion though. – tangokhi Nov 11 '16 at 08:41
