A simple example of how to use the StreamReader class to read a text file using C#.

namespace ConsoleApplications
{
    class StreamReaderDemo
    {
        static void Main(string[] args)
        {
            string pathFile = "book.txt";
            string contentFile = String.Empty;

            try
            {
                if (File.Exists(pathFile))
                {
                    StreamReader sr = File.OpenText(pathFile);
                    contentFile = sr.ReadToEnd();
                    sr.Close();

                    // Print the content
                    Console.WriteLine(contentFile);
                }
                else
                {
                    // Print the message
                    Console.WriteLine("It was not possible to find the file {0}", pathFile);
                }
            }
            catch (Exception excp)
            {
                Console.WriteLine("Error:" + excp.ToString());
