using System.Linq;
using System.IO;
namespace csvreaderfile
{
class Program
{
static void Main(string[] args)
{
//Reading the csv file and storing it in an array
string[] arr = File.ReadAllText("..//doc.csv").Split(',');
for(int i=0;i<arr.Length;i++)
{
Console.WriteLine(arr[i]);
}
Console.ReadLine();
//string content to write it to the next row
string val = "7,8,9,10,11,12";
File.AppendAllText("..//doc.csv", val);
}
