Setting FileSystemWatcher

I have to watch for changes in INI file so needed somehow to put an event which should trigger an action in my program.FileSystemWatcher class is exactly what I needed.It’s easy to use and very helpful so I will paste the codesnippet that I have found:

using System;
using System.IO;

namespace Client.Chapter_11___File_and_Streams
{
  public class TestChapter_11___File_and_Streams {
    public static void Main(string[] args)
        {
             FileSystemWatcher watcher = new FileSystemWatcher();
       watcher.Path = @"c:\Test";
             watcher.NotifyFilter  =
                          NotifyFilters.LastAccess |
                          NotifyFilters.LastWrite |
                          NotifyFilters.FileName |
                          NotifyFilters.DirectoryName;
             watcher.Filter = "*.txt";
             watcher.Changed += new FileSystemEventHandler(OnChanged);
             watcher.Created += new FileSystemEventHandler(OnChanged);
             watcher.Deleted += new FileSystemEventHandler(OnChanged);
             watcher.Renamed += new RenamedEventHandler(OnRenamed);
             watcher.EnableRaisingEvents = true;
                         
        }
    
    public static void OnChanged(object source, FileSystemEventArgs e)
        {
               Console.WriteLine("Event Fired");
        }
    public static void OnRenamed(object source, RenamedEventArgs e)
    {
      Console.WriteLine("Event Fired");
    }
  
  }
}

Another good example from the CodeProject.
