title: Convert DateTime to US is not good
body: <p>I have a DateTimePicker in WPF.
  The dateTimePicker give me an European Format</p>
  
  <p>In my DateTimePicker, i select "01/02/2014" ( in european format )</p>
  
  <p>I would like to read the value, and convert it in a shortDateString with the US culture.</p>
  
  <p><strong>I have done this :</strong></p>
  
  <pre><code>CultureInfo m_UsCulture = new CultureInfo("en-us");
  string str = m_dDate.Date.ToShortDateString().ToString(m_UsCulture);
  </code></pre>
  
  <p><strong>The str variable is</strong> : "01/02/2014" instead of "2/1/2014"</p>
  
  <p>The ShortDateString appear to be OK, but not the "ToString(m_UsCulture);".</p>
  
  <p>I would like to do this in a one line please. Have you an idea for this error ?</p>
  
  <p>Thanks a lot :)</p>
