Retrive only replacement template of regex in C#

can i get only the substitution of the Regex.Replace?
Example.

String text = @"asdfgs sda gsa ga s
SECTOR:124 NAME:Ricko
asdfgs sda gsa ga s";
String regex = "^SECTOR:(\d+) NAME:(\w+)";
String substitution = "$2 $1";

String result = Regex.Replace(text, regex, substitution);

Console.WriteLine(result);

Normal result

asdfgs sda gsa ga s
Ricko 124

Wanted result

Ricko 124

>Solution :

You are not matching all the characters around what you want to keep that should be deleted.

You could have the dot match a newline and using the multiline flag for the anchor.

(?sm).*?^SECTOR:(\d+) NAME:(\w+).*

The pattern matches:

• (?sm) Inline flags having the dot matching a newline and multiline
• .*? Match any character including a newline as least as possible
• ^ Start of string
• SECTOR:(\d+) NAME:(\w+) Capture 1+ digits in group 1 for SECTOR: and capture 1+ word chars in group 2 for NAME:
• .* Match the rest of the lines

Example

String text = @"asdfgs sda gsa ga s
SECTOR:124 NAME:Ricko
asdfgs sda gsa ga s";
String regex = @"(?sm).*?^SECTOR:(\d+) NAME:(\w+).*";
String substitution = "$2 $1";

String result = Regex.Replace(text, regex, substitution);

Console.WriteLine(result);

Output

Ricko 124
