body: <p>I am using Csvhelper (version 2.16) to write the records to csv file.</p>
  
  <p><a href="https://joshclose.github.io/CsvHelper/#getting-started" rel="nofollow">https://joshclose.github.io/CsvHelper/#getting-started</a></p>
  
  <p>I want to keep leading zeros when generated csv file is opened in excel format,
  so i have used UseExcelLeadingZerosFormatForNumerics= true configuration while writing the csv file.</p>
  
  <pre><code>using (SqlDataReader dataReader = sqlHelper.ExecuteReader(sqlQuery, parameters))
                  {
                      using (StreamWriter writer = new StreamWriter(csvfilepathTowrite))
                      {
                          CsvConfiguration config = new CsvConfiguration
                          {
                              UseExcelLeadingZerosFormatForNumerics = true
                          };
  
                          var csv = new CsvWriter(writer, config);
  
                          if (dataReader != null)
                          {
                              for (var i = 0; i &lt; dataReader.FieldCount; i++)
                              {
                                  csv.WriteField(dataReader.GetName(i));
                              }
                              csv.NextRecord();
                              while (dataReader.Read())
                              {
                                  for (var i = 0; i &lt; dataReader.FieldCount; i++)
                                  {
                                      csv.WriteField(dataReader[i]);
                                  }
                                  csv.NextRecord();
                              }
                          }
                          else
                          {
                             //exception
                          }
                      }
                  }

  <p>What might be the problem here?</p>
