const string input = "http://www.youtube.com/watch?v=bsidlcf5u3s " +                      "https://www.youtube.com/watch?v=bsidlcf5u3s " +                      "http://youtu.be/bsidlcf5u3s " +                      "www.youtube.com/watch?v=bsidlcf5u3s " +                      "youtu.be/bsidlcf5u3s " +                      "http://www.youtube.com/watch?feature=player_embedded&v=bsidlcf5u3s " +                      "www.youtube.com/watch?feature=player_embedded&v=bsidlcf5u3s " +                      "http://www.youtube.com/watch?v=_-qpudvtdny"; const string pattern = @"(?:https?:\/\/)?(?:www\.)?(?:(?:(?:youtube.com\/watch\?[^?]*v=|youtu.be\/)([\w\-]+))(?:[^\s?]+)?)"; const string replacement = "<iframe title='youtube video player' width='480' height='390' src='http://www.youtube.com/embed/$1' frameborder='0' allowfullscreen='1'></iframe>";  var rgx = new regex(pattern); var result = rgx.replace(input, replacement);  // result == // <iframe title='youtube video player' width='480' height='390' src='http://www.youtube.com/embed/bsidlcf5u3s' frameborder='0' allowfullscreen='1'></iframe> // ...
