I have a string value as follow

([68_89]+([65_79]/100)) + (([68_111]*12)*([65_79]/([IC_555]*12)-100))

If i try to use following regex for the related string value

MatchCollection matchList = Regex.Matches(formulaWithPrefix, @"((?:\w+|\((?1)\))(?:[+*^-](?1)|)?)", RegexOptions.ECMAScript);

I got the following excepition:

unrecognized grouping construct

What value should I change in regex to solve this issue

Any help will be appreicated.

Thanks

.NET regex does not support recursion and subroutines – Wiktor Stribiżew Dec 20 '19 at 11:39
For the time being, you might as well use `\w+`. – Wiktor Stribiżew Dec 20 '19 at 11:42
@WiktorStribiżew Could you share example according to given string regex ? – Soner Dec 20 '19 at 11:45
I used your string and regex in regex101 tester and saw that it yielded the same results as `\w+` did – Wiktor Stribiżew Dec 20 '19 at 11:46
