Question

What is the syntax for finding and selecting part of a string in Regx C#?

The string could be:

string tdInnerHtml = "<strong> You gained  230 Points </strong> 
                      there is going to be more text and some html code part of this       
                      string <a href=http://google.com>Google it here </a>";

// I want to extract 230 from this string using Regx. 
// The digits (230) vary for each tdInnerHtml. 
// So code would be to look for digits, followed by space, ending with Points

Answer 1

If the space and the </strong> tag are consistent, you can use the following to get the match there, and will work with strings like: “ Pints are between 230-240 Points and You gained 230 Points “

        var match = Regex.Match(tdInnerHtml, @"(?<pts>\d+) Points ?</strong>");
        if (match.Success) {
            int points = Convert.ToInt32(match.Groups["pts"].Value);
            Console.WriteLine("Points: {0}", points);
        }
