FileSystemWatcher.Renamed-Ereignis

Tritt ein, wenn im angegebenen Path eine Datei oder ein Verzeichnis umbenannt wird.

Namespace: System.IO
Assembly: System (in system.dll)

public event RenamedEventHandler Renamed
/** @event */
public void add_Renamed (RenamedEventHandler value)

/** @event */
public void remove_Renamed (RenamedEventHandler value)

JScript unterstützt die Verwendung von Ereignissen, aber nicht die Deklaration von neuen Ereignissen.

Ein Umbenennen des überwachten Verzeichnisses löst keine Benachrichtigung aus. Benachrichtigungen werden nur für Einträge im überwachten Verzeichnis ausgelöst.
