问个正则分组

[swordman123]

IF THE FARE COMPONENT INCLUDES TRAVEL BETWEEN HND AIRPORT
AND SEL
ON DIRECT FLIGHTS
OUTBOUND -
PERMITTED 201PM TO MIDNIGHT DAILY ON THE FIRST
INTERNATIONAL SECTOR.
INBOUND -
PERMITTED 1201AM TO 200PM DAILY DEPARTURE OF LAST
INTERNATIONAL SECTOR.
OTHERWISE
PERMITTED 1201AM TO MIDNIGHT DAILY.

我想分成两组
A:
IF THE FARE COMPONENT INCLUDES TRAVEL BETWEEN HND AIRPORT
AND SEL
ON DIRECT FLIGHTS
OUTBOUND -
PERMITTED 201PM TO MIDNIGHT DAILY ON THE FIRST
INTERNATIONAL SECTOR.
INBOUND -
PERMITTED 1201AM TO 200PM DAILY DEPARTURE OF LAST
INTERNATIONAL SECTOR.

B:
PERMITTED 1201AM TO MIDNIGHT DAILY.

这样的正则，解析不出来。
(?<A>\s+.*)\sOTHERWISE(?<B>\s+.*)

(.*SECTOR\.)(.*)

$1对应第一部分，$2对应第二部分

(.*)[\n\r]*OTHERWISE[\n\r]*(.*)

看错你的要求了，这个才是

[swordman123]

想要这种效果 string reg = @"(?<A>\s+.*)\sOTHERWISE(?<B>\s+.*)"; var arr = Regex.Matches(str, reg, RegexOptions.IgnoreCase); foreach (Match item in arr) { Console.WriteLine("A：" + item.Groups["A"]); Console.WriteLine("============================="); Console.WriteLine("b：" + item.Groups["B"]); } Console.ReadLine();
