You can open a text file and read each line.

• The StreamReader represents a text file that can process one

line at a time.

• We use the ReadLine method to obtain a single line of text.
• When the file has been exhausted the string returned will be null.

The text file http://progzoo.net/haggis.txt includes some lines of text.

.

using System; using System.IO; public class Demo{ public static void Main(string[] argv) { StreamReader fh = new StreamReader("haggis.txt"); string s; while ((s=fh.ReadLine())!=null) Console.WriteLine(s); fh.Close(); } }
