I'm not familiar with the use of double quotes in regexes.  However, you 
seem to have the right idea.  Instead of quotes, try using \\ in place 
of each \ you want to match.  E.g.:

^\\(\\[A-Za-z0-0_-]+)+\\?$

Quick explanation

\\ - Must start with a single backslash

(\\[A-Za-z0-0_-]+)  - A pattern representing a backslash followed by one 
or more valid letters/numbers/symbols.  If - is the last character in a 
[ ] block, it loses its special meaning and just matches -. 



The pattern is wrapped in () and specified to occur 1 or more times with 
+. 

Finally, there's a trailing \\? saying the path may optionally end with 
\.  Don't know if you want that or not.

NOTE: this pattern won't allow "\\".  Don't know if that matters.

I am trying to write a regular expression to represent a network path.
Network paths are of the form
\\path\to\folder
The regular expression which I thought would achieve this is
^"\"{2}([A-Za-z0-9]"-_")+"\"{1}([A-Za-z0-9]"-_\")+$
But I am having no luck. Can anyone help?
Thanks
