Lesson 11:

Exercise 11.6:

ArrayList duplicate a text file


Objetive:

Create a program that reads from a text file and stores to another text file inverting the lines.

So, an input text file like:

ayer el Madrid
le ganĂ³
al Barcelona

will be stored in an output text file like:

al Barcelona
le ganĂ³
ayer el Madrid


Source Code:


using System;
using System.IO;
using System.Collections;
namespace TextFileInvert
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Introduce el nombre del fichero: ");
            string nombreArchivo = Console.ReadLine();

            if (!File.Exists(nombreArchivo))
            {
                Console.Write("El archivo no existe!");
                return;
            }

            try
            {
                StreamReader miArchivo;
                miArchivo = File.OpenText(nombreArchivo);
                string line;

                ArrayList miLista = new ArrayList();

                do
                {
                    line = miArchivo.ReadLine();
                    if (line != null)
                        miLista.Add(line);
                }
                while (line != null);

                miArchivo.Close();

                StreamWriter miArchivoAlReves = File.CreateText(
                    nombreArchivo + "-reverse.txt");

                int tamanyoArchivo = miLista.Count;
                for (int i = tamanyoArchivo - 1; i >= 0; i--)
                {
                    miArchivoAlReves.WriteLine(miLista[i]);
                }

                miArchivoAlReves.Close();

            }
            catch (Exception e)
            {
                Console.WriteLine("Error, " + e.Message);
            }
            Console.ReadLine();
        }
    }
}
