title: Appending text to FTP instead of overwriting
body: <p>I'm trying to <strong><em>append</em></strong> a line of text to a txt file online, but the code I've tried is replacing all the txt in the file as opposed to adding a new line, even after adding <code>Enviorment.Newline</code>.</p>
  
  <p>Here's what I've tried:</p>
  
  <pre><code>  private void submithsbtn_Click(object sender, EventArgs e)
      {
          WebClient client = new WebClient();
          client.Credentials = new NetworkCredential("username", "password");
  
          string peak = peakvaluelbl.Text;
          string dir = @"ftp://example.com/file.txt";
          string name = nametbox.Text;
  
         client.UploadString(dir, name + " recived a peak score of: " + peak + Environment.NewLine);        
      }
  </code></pre>
  
  <p>Does anyone know how I might be able to achieve the result?</p>
