FileSystemWatcher.Renamed Event
.NET Framework 3.0
Occurs when a file or directory in the specified Path is renamed.
Namespace: System.IO
Assembly: System (in system.dll)
Assembly: System (in system.dll)
The following example uses the Renamed event to display the file path to the console whenever the watched file is renamed.
public class Watcher { public static void Main() { Run(); } [PermissionSet(SecurityAction.Demand, Name="FullTrust")] public static void Run() { string[] args = System.Environment.GetCommandLineArgs(); // If a directory is not specified, exit program. if(args.Length != 2) { // Display the proper way to call the program. Console.WriteLine("Usage: Watcher.exe (directory)"); return; } // Create a new FileSystemWatcher and set its properties. FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = args[1]; /* Watch for changes in LastAccess and LastWrite times, and the renaming of files or directories. */ 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. watcher.EnableRaisingEvents = true; // Wait for the user to quit the program. Console.WriteLine("Press \'q\' to quit the sample."); while(Console.Read()!='q'); } // Define the event handlers. private static void OnChanged(object source, FileSystemEventArgs e) { // Specify what is done when a file is changed, created, or deleted. Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType); } private static void OnRenamed(object source, RenamedEventArgs e) { // Specify what is done when a file is renamed. Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath); } }
public class Watcher
{
public static void main(String[] args1)
{
Run();
}
/** @attribute PermissionSet(SecurityAction.Demand, Name="FullTrust")

String args[] = System.Environment.GetCommandLineArgs();
// If a directory is not specified, exit program.

return;
}
// Create a new FileSystemWatcher and set its properties.
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.set_Path(args[1]);
/* Watch for changes in LastAccess and LastWrite times, and
the renaming of files or directories.
*/
watcher.set_NotifyFilter
(NotifyFilters.LastAccess |NotifyFilters.LastWrite |
NotifyFilters.FileName | NotifyFilters.DirectoryName);
// Only watch text files.
watcher.set_Filter("*.txt");
// Add event handlers.

{
// Specify what is done when a file is renamed.
Console.WriteLine("File: {0} renamed to {1}",
