Extracting substring Regex

Question

I have the following string

[function('lookup')]

I want to extract the string lookup from the string above.

Tried doing using

var lookup = Regex.Match("[function('lookup')]", @"'\b\w*\b'").Value;

I end up getting 'lookup' with the single quotes instead of just lookup.

Where am I going wrong ?

Well yes, your pattern includes the quotes. Why would you expect it not to include the quotes? You could either just strip them off the front and back, or put a capturing group inside the quotes. — Jon Skeet

If I remove the quotes I end up with function. Is there a better way to directly extract out lookup ? — Frank Q.

No, I mean remove the quotes from the result. But yes, you could use a capturing group... — Jon Skeet

You can do it as:

var lookup = Regex.Match("[function('lookup')]", @"'\b(\w*)\b'").Groups[1].Value;
