c# - Storing a DataTable in a Flatfile -

this first time have done sort of work flat files. need plain txt file not xml.

i have written following opting comma delimited format.

    public static void datatabletofile(string fileloc, datatable dt)     {         stringbuilder str = new stringbuilder();         // column headers         foreach (datacolumn c in dt.columns)         {             str.append(c.columnname.tostring() + ",");         }         str.remove(str.length-1, 1);         str.appendline();         // write data here         foreach (datarow dr in dt.rows)         {             foreach (var field in dr.itemarray)             {                 str.append(field.tostring() + ",");             }             str.remove(str.length-1, 1);             str.appendline();         }         try         {             write(fileloc, str.tostring());         }         catch (exception ex)         {             //todo:add error logging         }     } 

my question is: can better or faster? , str.remove(str.length-1, 1); there remove last , way think of. suggestions?

use

public static void datatabletofile(string fileloc, datatable dt) {     stringbuilder str = new stringbuilder();      // column headers     str.append(string.join(",", dt.columns.cast<datacolumn>()                                       .select(col => col.columnname)) + "\r\n");      // write data here     dt.rows.cast<datarow>().tolist()            .foreach(row => str.append(string.join(",", row.itemarray) + "\r\n"));      try     {         write(fileloc, str.tostring());     }     catch (exception ex)     {         //todo:add error logging     } }
