title: FileHelpers -- Only read Nth Columns
body: <p>I am using <a href="http://filehelpers.sourceforge.net/" rel="nofollow noreferrer">FileHelpers</a> to read a CSV file that have hundreds of columns but I only need the first twenty or so, so while creating the mappings in the class I only put those twenty columns.</p>
  
  <p>When do the parsing, I get the following exception</p>
  
  <blockquote>
    <p>Delimiter ',' found after the last field 'CompanyDivision' (the file
    is wrong or you need to add a field to the record class)</p>
  </blockquote>
  
  <p>I read in other answers that a <strong>hack</strong> for this is to put dummy fields for the rest of the columns you don't want to read but, as I said, I have hundreds of those.</p>
  
  <p>Is there a way to configure the engine to stop after a certain number of columns? or is there a way to extend or modify the engine to do this?</p>
