Try: ^Two as pattern,
^ means: match start of string ;)

I'm not sure exactly what you are looking for, but to ensure that the line contains "two" only, without other words, match to the beginning of the line:

^Two: (?'two'\d+)$

The named group "(?'two'\d+)" will capture all digits to the end of the line and put them in a group called "two".

Thanks for your comment. I want to capture only "Two: 2". In this case match count should be 1..

What result are you getting? The caret ^ ensures that the line has to start with the matching text, so it should match only one line from your sample.

getting zero count.

Be sure you specify the RegexOptions.Multiline option to change the meaning of ^ and $ to be per line.

still getting zero count for below code
MatchCollection matches = Regex.Matches(Txt, regX, RegexOptions.Multiline);

Solution 3
