One of my action outputs a csv file. The problem is if a field contains comma, then it splits the datarow into two fields. I tried using “\”” to include each row in double quotes but this is not working. Could someone guide me in the right direction?

UPDATE

var sw = new StringWriter();
            sw.WriteLine(String.Format("{0},{1},{2},{3},{4},{5},{6},{7},{8},{9},{10},{11},{12},{13}", "First Name","Last Name","Address1","Address2","City","State","Postal Code","Country","Dealer ID","Dealer Name","Survey Source","Amount","Email","Survey Code"));
            sw.WriteLine(String.Format("\"{0}\",\"{1}\",\"{2}\",\"{3}\",\"{4}\",\"{5}\",\"{6}\",\"{7}\",\"{8}\",\"{9}\",\"{10}\",\"{11}\",\"{12}\",\"{13}\"",  model.SurveyWinnerDetails.Select(p => p.FirstName).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.LastName).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.Address1).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.Address2).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.City).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.State).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.PostalCode).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.CountryCode).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.DealerID).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.DealerName).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.SurveySource).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.Amount).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.Email).First().Replace("\"", "\"\""),
                        model.SurveyWinnerDetails.Select(p => p.SurveyCode).First().Replace("\"", "\"\"")));
            return File(new System.Text.UTF8Encoding().GetBytes(sw.ToString()), "text/csv", "SurveyWinner.csv");

When i run this now, I get an error: Object reference not set to the instance of an object.

    There’s no one “official” CSV format, though the most common is outlined in RFC 4180 (http://tools.ietf.org/html/rfc4180). According to that RFC (section 6), fields containing commas should be enclosed in double quotes.

    Per @Axam’s observation below, RFC 4180 does not allow for extra whitespace around the commas. Change your format string to:

    "{0},{1},{2},{3},{4},{5},{6},{7},{8},{9},{10},{11},{12},{13}"
