title: Get date creation of a text file
body: <p>I wrote a piece of code in c# to get the date of creation of a text file and to have the date in <code>yyyyMMddHHMMSS</code> format  :</p>
  
  <pre><code>FileInfo fileInfo = new FileInfo("test.txt");
  DateTime fileCreatedDate = fileInfo.CreationTime;
  string dateCreation = fileCreatedDate.ToString("yyyyMMddHHMMSS");
  </code></pre>
  
  <p>But it didn't work, <code>dateCreation</code> is for example: <code>201401291001SS</code></p>
  
  <p>How can I modify it ?</p>
