c# - Match vertical slash -


how can match vertical slash | in regular expression

i've trying match content "1|2|3|4|" regex expression
"(<group1>.*?)|.*?|.*?|(<group2>.*?)|

i'd in first group value 1 , in second 4 regular expression not working

what have close, remove question marks. asterisks match 0 or more there's not need question marks.

the \ escapes |. you're missing couple slashes. should like:

(<group1>.*)\|.*\|.*\|(<group2>.*)\|

and you'll need add @ sign in front of string declaration c# take literal text.

@"backslash\all day"
