Regex Group Contains

hey simple easy question, but are there ways to access individual capture groups in a regex match? I want to say

if(regex.Group(2).contains("401") {
//do some stuff with
}

if(regex.Group(2).contains("401") {
//do some stuff with
}

regexMatch.Groups[2].Value.Contains("401")

thanks brotha looks like a match class word

Omnissiah•12mo ago

you could consider using named groups (?<name>pattern)

TheRanger•12mo ago

if you did that you can access the group like this

regexMatch.Groups["name"].Value.Contains("401")

regexMatch.Groups["name"].Value.Contains("401")

perf i appreciate it guys that looks like its in the actual regex declaration? hang on

^(<name>(ADIP)(\\d*)?([/])?([A-Za-z])*(\\d)*(\\.)?(\\d{1,2}))$

^(<name>(ADIP)(\\d*)?([/])?([A-Za-z])*(\\d)*(\\.)?(\\d{1,2}))$

is that right?

TheRanger•12mo ago

u forgot a ? before <name>

mrdudebro1OP•12mo ago

oops

^(?<name>(ADIP)?<name2>(\\d*)??<name3>([/])?([A-Za-z])*(\\d)*(\\.)?(\\d{1,2}))$

^(?<name>(ADIP)?<name2>(\\d*)??<name3>([/])?([A-Za-z])*(\\d)*(\\.)?(\\d{1,2}))$

huh there's 2 questions marks in there now. i can do some debugging no worries

Omnissiah•12mo ago

something doesn't look right

mrdudebro1OP•12mo ago

yeah i already have a star in there i should probably remove the first question mark lol idk tbh i can't debug atm i will later

^(?<name>(ADIP)(?<name2>(\d*))(?<name3>([/]))?([A-Za-z])*(\d)*(\.)?(\d{1,2}))$

^(?<name>(ADIP)(?<name2>(\d*))(?<name3>([/]))?([A-Za-z])*(\d)*(\.)?(\d{1,2}))$

Omnissiah•12mo ago

i mean there are no ( before name2 and name3 ah ok

mrdudebro1OP•12mo ago

just had to put parantehses around it lmao

Omnissiah•12mo ago

also why capture the whole name group, it's just constant+name2

mrdudebro1OP•12mo ago

ope didn't mean to do that tbh
