title: File.WriteAllText issue
body: <p>I am trying to save a number of different forms to a text file, currently I have:</p>
  
  <ul>
  <li>Temperature</li>
  <li>Wind</li>
  <li>Rain</li>
  <li>Cloud</li>
  </ul>
  
  <p>The issue that I'm having is that it only saves the "Cloud" data.  Is there a way I can save all the information on submission and have them separated by a comma, dash, or just a space?</p>
  
  <p>This is the code I'm currently using:</p>
  
  <pre><code>  private void button2_Click(object sender, RoutedEventArgs e)
      {
  
          File.WriteAllText("C:\\WeatherSpotter.txt", tempC.Text);
          File.WriteAllText("C:\\WeatherSpotter.txt", tempF.Text);
          File.WriteAllText("C:\\WeatherSpotter.txt", windMPH.Text);
          File.WriteAllText("C:\\WeatherSpotter.txt", windKM_Textbox.Text);
          File.WriteAllText("C:\\WeatherSpotter.txt", Cloud_ComboBox.Text);
  
  
      }
  </code></pre>
