Evento FileSystemWatcher.Renamed
.NET Framework 3.5
Aggiornamento: novembre 2007
Viene generato alla ridenominazione di un file o di una directory nella proprietà Path specificata.
Assembly: System (in System.dll)
Nell'esempio riportato di seguito viene utilizzato l'evento Renamed per visualizzare il percorso del file nella console ogni volta che il file controllato viene rinominato.
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); } }
