title: Retrieve string from the middle of a string
body: <p>I have a coded string that I'd like to retrieve a value from. I realize that I can do some string manipulation (<code>IndexOf</code>, <code>LastIndexOf</code>, etc.)  to pull out <code>12_35_55_219</code> from the below string but I was wondering if there was a cleaner way of doing so.</p>
