title: How do I get the assigned fixed length of the field from FileHelpers library?
body: <p>I am using FileHelpers library to write output files. Here is the sample code snippet:</p>
  
  <pre><code> public class MyFileLayout
   {
      [FieldFixedLength(2)]
      private string prefix;
  
      [FieldFixedLength(12)]
      private string customerName;
   }
  </code></pre>
  
  <p>In my code flow, I would like to know each of those fields assigned length at run time, for eg: it is 12 for customerName. </p>
  
  <p>Is there a way to get the values like above from FileHelpers library?</p>
