seek { using (streamwriter sw = new streamwriter("c:/projects/data/pyaegon1aegonresult.csv")) using (streamreader sr = new streamreader("c:/projects/data/pyaegon1aegon.csv")) { heading = "title, first name, surname, date of birth, ni number, gender, payroll reference, address line 1, address line 2, address line 3, address line 4, addressline 5, postcode, country, email, date joined employer, annual pensionable salary, current period earnings (monthly), current period pensionable earnings (monthly), emnployee (amount deducted), employer (amount deducted), leaving date."; sw.writeline(heading); while((txtline = sr.readline()) != null) { oldcolumns = regex.split(txtline,","); newcolumns[0] = oldcolumns[0]; newcolumns[1] = oldcolumns[1]; newcolumns[2] = oldcolumns[2]; newcolumns[3] = oldcolumns[3]; newcolumns[4] = oldcolumns[4]; newcolumns[5] = oldcolumns[5]; newcolumns[6] = oldcolumns[6]; newcolumns[7] = oldcolumns[7]; newcolumns[8] = oldcolumns[9]; newcolumns[9] = oldcolumns[10]; newcolumns[10] = oldcolumns[11]; newcolumns[11] = ""; newcolumns[12] = oldcolumns[12]; newcolumns[13] = "united kingdom"; newcolumns[14] = oldcolumns[14]; newcolumns[15] = oldcolumns[15]; newcolumns[16] = oldcolumns[16]; newcolumns[17] = oldcolumns[17]; newcolumns[18] = oldcolumns[18]; newcolumns[19] = oldcolumns[19]; newcolumns[20] = oldcolumns[20]; newcolumns[21] = ""; csvline = ""; (int = 0; < 21; i++) { csvline = csvline + "\"" + newcolumns[i].replace("\"","") + "\","; } sw.writeline(csvline); }

just phone call sr.readline() before start reading input.

using (streamwriter sw = new streamwriter("c:/projects/data/pyaegon1aegonresult.csv")) using (streamreader sr = new streamreader("c:/projects/data/pyaegon1aegon.csv")) { sr.readline(); // rest of code

c# csv
