.net - How do I specify a wildcard (for ANY character) in a c# regex statement?

Trying to use a wildcard in C# to grab information from a webpage source, but I cannot seem to figure out what to use as the wildcard character. Nothing I've tried works!

The wildcard only needs to allow for numbers, but as the page is generated the same every time, I may as well allow for any characters.

Regex statement in use:

Regex guestbookWidgetIDregex = new Regex("GuestbookWidget(' INSERT WILDCARD HERE ', '(.*?)', 500);", RegexOptions.IgnoreCase);

If anyone can figure out what I'm doing wrong, it would be greatly appreciated!

The wildcard character is ..
To match any number of arbitrary characters, use .* (which means zero or more .) or .+ (which means one or more .)

Note that you need to escape your parentheses as \( and \). (or ( and ) in an @"" string)
