Lesson 8:

File management

Exercise 8.7:

Text replacer


Create a program to replace words in a text file, saving the result into a new file.

The file, the word to search and word to replace it with must be given as parameters:

replace file.txt hello goodbye

The new file would be named "file.txt.out" and contain all the appearances of "hello" replaced by "goodbye".

Source Code:

using System;
using System.IO;
namespace Replace
    class Program
        static void Main(string[] args)
            ReplaceTextFile("file.txt", "Hola", "hola");

        public static void ReplaceTextFile(string urlFile, string textReplace, string newText)
            StreamReader myfileRd = File.OpenText(urlFile); ;
            StreamWriter myfileWr = File.CreateText("file.txt.out"); ;
            string line = " ";
                line = myfileRd.ReadLine();
                if (line != null)
                    line = line.Replace(textReplace, newText);
            while (line != null);
