body: <p>I have tried this but it's giving me an error: </p>
  
  <blockquote>
    <p><em>"The given path's format is not supported".</em></p>
  </blockquote>
  
  <pre><code>private void btnVerify_Click(object sender, EventArgs e)
  {
      int counter = 0;
      string email = textVarify.Text;
      string line="";
      System.IO.StreamReader file = new System.IO.StreamReader("https://dl.dropboxusercontent.com/u/9013501/bots/lic.txt");
      while ((line = file.ReadLine()) != null)
      {
          if (line.Contains(textVarify.Text))
          {
              DevComponents.DotNetBar.MessageBoxEx.Show("Email",textVarify.Text+" Found");
          }
          counter++;
      }
  
      file.Close();
  }
