title: How to get short month name from full month name?
body: <p>I need to get the short month name for the full month name.</p>
  
  <p>For example,</p>
  
  <pre><code>DateTime.Now.ToString("MMMM", CultureInfo.CurrentCulture);
  this returns - "agosto"
  
  DateTime.Now.ToString("MMM", CultureInfo.CurrentCulture);
  this returns - "ago."
  </code></pre>
  
  <p>This two codes works only to get the current month. I need to get the short month name for all the months. </p>
  
  <p>If I give <code>"agosto"</code>, it should return <code>"ago."</code>. How could I achieve this?</p>
