1. File.ReadAllLines

using System;
using System.IO;

public class ReadFile
{
    public static void Main()
    {
      string FileToRead = @"D:\New folder\textFile.txt";
      using (StreamReader ReaderObject = new StreamReader(FileToRead))
      {
          string Line;
          // ReaderObject reads a single line, stores it in Line string variable and then displays it on console
          while((Line = ReaderObject.ReadLine()) != null)
          {
              Console.WriteLine(Line);
