I thought I used this expression (below) with success, but Expresso Regex Builder keeps returning this error:

Error: Invalid Group Name. Group names must begin with a word character

I'm trying to extract everything between ^ and ^ but exclude both ^

(?<\^).*(?=\^)

The syntax (?<groupname>pattern) can be used to name a capture group.  The assertions are probably overkill for something like this anyway.  You can get your data by utilizing your capture groups.  Note: the ^ character is an anchor, so they are escaped in the expression.

\^(.*?)\^

This: \^(.*?)\^
Returns this: ^12345678^
I also need to exclude both ^ from the result...

Check the second group:
Match match = Regex.Match("^12345^", "\^(.*?)\^");
 
string result = match.Groups[1].Value;
