Slight modification to the comment I posted in your other question:

using System.Text.RegularExpressions;

...

Match m = Regex.Match(targetString, @"\b(?:[ ]*[a-zA-Z\d]){8}\b");

if (m.Success)
{
    string numericalValue = m.Groups[0].Value;
}

Hi

Having a bit of a problem with this, the string will always contain a mix of both numbers and letters. At the moment the regex is picking up strings with just letters.

The "\d" in the pattern should account for numbers. Can you provide some sample inputs?

The matches should be a mix including BOTH numbers and letters.

I have a large body of text, and "whatsapp" is being returned. This does not include both numbers and letters, and so should not match.

OK, I thought by "mix" you meant either all letters, all numbers, or all letters and numbers. I see now that you mean the latter.

Try:

\b(?=[a-zA-Z]*\d)(?=\d*[a-zA-Z])[a-zA-Z\d]{8}\b

Actually, I need to revise the above to account for the spaces. Uno momento.

Updated:

\b(?=[ \d]*[a-zA-Z])(?=[ a-zA-Z]*\d)(?: *[a-zA-Z\d]){8}\b

The last solution that deals with spaces picked up "february", but never mind, the example above is working fine and I don't think I will see any spaces. Thank you so much for the help! I appreciate it
