Code
var regex = new Regex(@"[\n\r].*Id:\s*([^\n\r]*)");
var useridText = regex.Match(extractedDocContent).Value;
CodePudding user response:
You can use
var regex = new Regex(@"(?<=Id:[^()]*\()\d ");
See the regex demo.
Details:
(?<=Id:[^()]*\()
- a positive lookbehind that matches a location that is immediately preceded withId:
zero or more chars other than(
and)
(
\d
- one or more digtis.
Consider also a non-lookbehind approach:
var pattern = @"Id:[^()]*\((\d )";
var useridText = Regex.Match(extractedDocContent, pattern)?.Groups[1].Value;
