Sample 1 demonstrates how to use the StreamReader technique when reading the contents of a file

[C# Version]

using System;
using System.IO;

namespace KeithRull.ReadMyFile
{
    class Program
    {
        static void Main(string[] args)
        {
            //the filename of the file to read
            string xmlFilename = "Symbols.xml";
          
            //validate if the file exist
            if (File.Exists(xmlFilename))
            {
                //create a new StreamReader object tha would read the file
                using (StreamReader sReader = new StreamReader(xmlFilename))
                {
                    //create a string object that would hold the
                    //value of each line in our file
                    string line = String.Empty;
                    
                    //iterate for each line item in our file
                    while ((line = sReader.ReadLine()) != null)
                    {
                        //display the output in the screen
                        Console.WriteLine(line);
                    }
                }
            }
            else
            {
                //notify that the file was not found
                Console.WriteLine("File not found!");
            }

            //pause and wait for the user.
            Console.ReadLine();
        }
    }
}
