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.
