title: Local path URI in C# WPF
body: <p>If I use an open file dialog box that returns the absolute value of the file this works just fine:</p>
  
  <pre><code>  BMP = new BitmapImage(new Uri(filename));
  </code></pre>
  
  <p>However, I want to have a text file that contains the names of the files, like this:</p>
  
  <pre><code>01TopographicalMap.bmp
  01ElevationCompressed.elv
  01Terrain.trn
  01Placenames.pns
  </code></pre>
  
  <p>These files are loaded sequentially. Unfortunately, the previous Uri(filename) call barfs because it wants the whole absolute path. We're already in the same folder. What do I have to do to get the Uri to just default to the folder it's already in?</p>
  
  <p>Thanks, for the help.</p>
