title: Invalid URI: The format of the URI could not be determined
body: <p>I keep getting this error.</p>
  
  <blockquote>
    <p>Invalid URI: The format of the URI could not be determined.</p>
  </blockquote>
  
  <p>the code I have is:</p>
  
  <pre><code>Uri uri = new Uri(slct.Text);
  if (DeleteFileOnServer(uri))
  {
      nn.BalloonTipText = slct.Text + " has been deleted.";
      nn.ShowBalloonTip(30);
  }
  </code></pre>
  
  <p><strong>Update:</strong> the content in slct.Text is <code>ftp.jt-software.net/style.css</code>.</p>
  
  <p>What gives? How is that not a valid URI format? It's plain text.</p>
