Code:

using System;
using System.IO;
class Test
{
    public static void Main()
    {
        string path = @"c:\sri\srip.txt";
        try
        {
            if (File.Exists(path))
            {
                File.Delete(path);
            }
            using (StreamWriter sw = new StreamWriter(path))
            {
                sw.WriteLine("This");
                sw.WriteLine("text is");
                sw.WriteLine("to test");
                sw.WriteLine("Reading");
            }

            using (StreamReader sr = new StreamReader(path))
            {
                while (sr.Peek() >= 0)
                {
                    Console.WriteLine(sr.ReadLine());
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
