FileSystemWatcher.Renamed Event

Occurs when a file or directory in the specified Path is renamed.

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

'Declaration
<IODescriptionAttribute("FSW_Renamed")> _
Public Event Renamed As RenamedEventHandler
'Usage
Dim instance As FileSystemWatcher 
Dim handler As RenamedEventHandler 

AddHandler instance.Renamed, handler

Renaming the directory you are watching will not raise a notification. Notifications are only raised for entries inside the directory you are watching.

The following example uses the Renamed event to display the file path to the console whenever the watched file is renamed.

Imports System.IO
Imports Microsoft.VisualBasic
Imports System.Security.Permissions

    Public Shared Sub Main()
	
         Run()

    End Sub

    Private Shared Sub Run

      Dim args() As String = System.Environment.GetCommandLineArgs()
        ' If a directory is not specified, exit the program. 
        If args.Length <> 2 Then 
            ' Display the proper way to call the program.
            Console.WriteLine("Usage: Watcher.exe (directory)")
            Return 
        End If 

        ' Create a new FileSystemWatcher and set its properties. 
        Dim watcher As 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 Or NotifyFilters.LastWrite Or NotifyFilters.FileName Or NotifyFilters.DirectoryName)
        ' Only watch text files.
        watcher.Filter = "*.txt" 

        ' Add event handlers. 
        AddHandler watcher.Changed, AddressOf OnChanged

        Console.WriteLine("Press 'q' to quit the sample.")
        While Chr(Console.Read()) <> "q"c
        End While 
    End Sub 

    ' Define the event handlers. 
    Private Shared Sub OnChanged(source As Object, e As FileSystemEventArgs)
        ' Specify what is done when a file is changed, created, or deleted.

        Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath)
