You did make a couple of mistakes, but you led me in the right direction. This is the right code in the middle:
return Pattern.Replace(String, match =>
{
var str = match.Groups[0].Value;
var provideStr = str.Substring(1, str.Length - 2);
var value = new StaticResourceExtension(provideStr).ProvideValue(serviceProvider);
return Convert.ToString(value);
});

Thanks for your response...Just what I was looking for.

Thanks so much I knew there was something, but I completely forgot (it was years ago) and it was hard to find the answer since most information on RegEx is the basic stuff, which is still hard to remember unless you work with it all the time. I figured there was some brain out there I could pick and appreciate that you took the time to answer.
