title: WP7 Isolated Storage Text Document Read Line
body: <p>Is there a way using Isolated storage ie a Text document, to grab the text on a certain line.
  I would like to save variables to a text document on my settings page of my app. Then go back to the main page and read the variable saved on line 3. I already know how to save them. just not read certain lines.</p>
  
  <p>Also is the text document created by my app going to still be there if i close and reopen the app?</p>
