title: FileHelpers .Net library Error - delimeter found after the last field of the class
body: <p>Visual Studio 2019, .Net Core 2.2 - getting the following error when debugging code to parse a csv file with 10 rows, using the FileHelpers .Net library:</p>
  
  <pre><code>{"Line: 2 Column: 593. Delimiter ',' found after the last field 'Taxonomy_Group_15' (the file is wrong or you need to add a field to the record class)"}
  </code></pre>
  
  <p>I have checked the file and I don't see anything in column 593 (or anywhere else beyond the defined columns for that matter).</p>
  
  <p>Here is the code I'm testing with:</p>
  
  <pre><code>public static void Main(string[] args)
          {
              var engine = new FileHelperEngine&lt;Entity&gt;();
  
              var result = engine.ReadFile(@"C:\Users\me\Desktop\pfile_20190902-20190908.csv");
  
                  foreach (Entity subject in result)
                      {
                      Console.WriteLine("Subject Info:");
                      Console.WriteLine(subject.NPI + " - " + subject.Entity_Type_Code);
                      }
          } 
  </code></pre>
  
  <p>The error is thrown before the foreach loop is entered. I've checked my Entity Class and all columns are present. Can someone help me understand what's going on here?</p>
