使用例
特定のファイル変更通知が行われるのを待機して、FileSystemWatcher を同期的に使用する例を次に示します。
Imports System.IO Module Module1 Sub Main() ' Define a path and a file name for a temporary file. Dim pathname As String = "C:\" Dim filename As String = "JunkFile.tmp" Dim filepathname As String = Path.Combine(pathname, filename) ' Create the temporary file and then close it. File.Create(filepathname).Close() Console.WriteLine("This application will terminate when you delete the {0} file", filepathname) ' Have a FileSystemWatcher monitor the path and file for changes. Dim fsw As New FileSystemWatcher(pathname, filename) fsw.NotifyFilter = NotifyFilters.FileName fsw.EnableRaisingEvents = True ' Suspend the calling thread until the file has been deleted. Dim cr As IO.WaitForChangedResult = fsw.WaitForChanged(WatcherChangeTypes.Deleted) ' Tell the user the file is deleted and exit. Console.WriteLine("The {0} files is deleted; program is exiting", cr.Name) End Sub End Module ' This code produces the following output. ' ' This application will terminate when you delete the C:\JunkFile.tmp file ' The JunkFile.tmp files is deleted; program is exiting
