Search Sub-Directories Also

Right now this code just searches 1 directory, how can i get it to search the original directory and all the sub-directories

Code:

---

Imports System.IO

Public Class Form1
    Dim strFileSize As String = ""
    Dim di As New IO.DirectoryInfo("C:\Pictures")

    Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")
    Dim fi As IO.FileInfo
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        For Each fi In aryFi
            If fi.Extension = ".jpg" Or fi.Extension = ".gif" Or fi.Extension = ".bmp" Or fi.Extension = ".png" Or fi.Extension = ".PNG" Or fi.Extension = ".JPG" Then ''etc etc etc
                ListBox1.Items.Add(fi.Name)
            End If
        Next

    End Sub
End Class

From VS IntelliSense with a little change...

VB.NET Code:

Dim files As ReadOnlyCollection(Of String)
        Dim wildcards() As String = {".jpg", ".gif", ".bmp", ".png"}
        files = My.Computer.FileSystem.GetFiles("C:\", FileIO.SearchOption.SearchAllSubDirectories, wildcards)

its not recognizing ReadOnlyCollection(Of String), saying it's not declared, i'm using .netframework 2.0 for this project

It is part of the System.Collections.ObjectModel namespace, so you may need an import on that.

Also, be careful with the SearchAllSubDirectories option on machines that are locked down, especially Vista machines. It will throw an exception and stop processing if it runs into files that it does not have access to.

OK I got it working, but it is stopping at stuff like documents & settings, is there any way to bypass these restrictions?

If you really want to search all directories, you can ignore all exceptions...

That won't work if you're using the recursive function shown above, because when it errors out it just won't return anything at all. You'll have to do a manual function to recurse through subdirectories and handle errors.
