        Match match = Regex.Match(input, @"content/(?:\s)(\w{8},)",
            RegexOptions.IgnoreCase);

        // Here we check the Match instance.
        if (match.Success)
        {
            // Finally, we get the Group value and display it.
            string key = match.Groups[1].Value;

Hi Dan;

Try placing this line of code for the same in your code.

 
Match match = Regex.Match(input, @"CN=.*([a-zA-Z1-9]{8}),", RegexOptions.IgnoreCase);

Thank you Fernanado. I used Rgonzo1971 earlier and it worked. I was incorreclty calling an expression as string.
