Question

I have this regex to read all lines after the value Description:

var descriptionMatches =
  Regex.Matches(source, @"\b(?<key>Description)\s*(?<value>\w+)");

The problem is, the returned value is only the first word, not the whole line.

What I’m missing,

Answer 1

Change \w+ to be .+. This will match all characters instead of just a series word characters (which does not include whitespace).

Also, if you want . to match newlines (you indicate that you want to match all lines after the description), then you must use the RegexOptions.Singleline option:

var descriptionMatches =
  Regex.Matches(source, @"\b(?<key>Description)\s*(?<value>.+)", RegexOptions.Singleline);
