title: Csvhelper - read / get a single column of all rows?
body: <p>Hi I'm using csvHelper to read in a csv files with a variable number of columns. The first row always contains a header row. The number of columns is unknown at first, sometimes there are three columns and sometimes there are 30+. The number of rows can be large. 
  I can read in the csv file, but how do I address each column of data. I need to do some basic stats on the data (e.g. min, max, stddev), then write them out in a non csv format.
  Here is my code so far...</p>
  
  <pre><code>try{
      using (var fileReader = File.OpenText(inFile))
      using (var csvResult  = new CsvHelper.CsvReader(fileReader))
      {
          // read the header line   
          csvResult.Read();
  
          // read the whole file
          dynamic recs = csvResult.GetRecords&lt;dynamic&gt;().ToList();
  
          /* now how do I get a whole column ???
           * recs.getColumn ???
           * recs.getColumn['hadername'] ???
           */
  
      }
      catch (Exception ex)
      {
          MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
      }
  </code></pre>
  
  <p>Thanks</p>
