OK. That's my code:
I have a code here:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace MyDirectoryWatcher
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("***** The Amazing File Watcher App *****\n");
// Establish the path to the directory to watch.
FileSystemWatcher watcher = new FileSystemWatcher();
try
{
watcher.Path = @"C:\MyFolder";
}
catch (ArgumentException ex)
{
Console.WriteLine(ex.Message);
return;
}
// Set up the things to be on the lookout for.
watcher.NotifyFilter = NotifyFilters.LastAccess
| NotifyFilters.LastWrite
| NotifyFilters.FileName
| NotifyFilters.DirectoryName;
// Only watch text files.
watcher.Filter = "*.txt";
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
// Begin watching the directory.
watcher.EnableRaisingEvents = true;
// Wait for the user to quit the program.
Console.WriteLine(@"Press 'q' to quit app.");
while (Console.Read() != 'q') ;
}
static void OnChanged(object source, FileSystemEventArgs e)
{
// Specify what is done when a file is changed, created, or deleted.
Console.WriteLine("File: {0} {1}!", e.FullPath, e.ChangeType);
}
static void OnRenamed(object source, RenamedEventArgs e)
{
// Specify what is done when a file is renamed.
Console.WriteLine("File: {0} renamed to\n{1}", e.OldFullPath, e.FullPath);
}
}
}
Why Changed event fires twice????
