Hello,

I have a regex and I want to modify the value of a named capture
before doing the regex.Replace.

So something like:

string text = Regex.Replace(oldText, myRegex, @"<a href="$1">$1</a>",
regexOptions);

Now I want to modify the value of the second $1 just in case it is too
long to display.

This doesn't work, but this is what I want to do somehow!

string text = Regex.Replace(oldText, myRegex,
                        String.Format(@"<a href="$1">{0}</a>",
MyFunction("$1")),
                      regexOptions);
