Buongiorno a tutti,

ho un file batch che generea in lista.txt tutti i percorsi  le foto present=
i in una cartella e relative sottocartelle (dir C:\miacartella\foto\*.jpg /=
b /on >C:\miacartella\foto\lista.txt)

l'ho tradotto in vb.net usando il seguente codice:

        For Each foundFile As String In
            My.Computer.FileSystem.GetFiles("C:\miacartella\foto\", FileIO.=
SearchOption.SearchAllSubDirectories, "*.jpg")
            foundFile =3D foundFile & vbCrLf
            My.Computer.FileSystem.WriteAllText("C:\miacartella\foto\LISTA.=
TXT", foundFile, True)
        Next


funziona ma ci mette troppo tempo rispetto al file batch (20 secondi per il=
 batch contro oltre il minuto per l'eseguibile vb.net)

E' un problema di metodo o si pu=C3=B2 cambiare codice migliorando le prest=
azioni?

grazie in anticipo

Nico
