title: Convert string to date with format (VB.net)
body: <p>I have a string with a date in this format. "24-11-2015" or "dd-MM-yyyy". I need to convert this to a date with this format. "2015-11-24" or "yyyy-MM-dd".
  I've tried several ways, and all of them rely on my system format for this to work. If i run my program on a computer with english time format this works.</p>
  
  <pre><code>Date.ParseExact("24-11-2015", "dd-MM-yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo)
  </code></pre>
  
  <p>But if i run it on a computer running danish format i get error because there is no 24th month. How do i make the date format independent of my system time format.</p>
