folders creation from listbox

[Pascal]

Hi everybody

I try to create folders from a list stored in a listbox. It works a
"little"but, i would like to create these folders only if they don't exist.
here is the code i use :

Private Sub btnCreateFolders_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnCreateFolders.Click
Try
Dim i As Integer
For i = 0 To lstbEleves.Items.Count - 1
' Open the path
Dim D As DirectoryInfo
D = New DirectoryInfo(ParentFolder)
Dim SD As DirectoryInfo
SD = New DirectoryInfo(lstbEleves.Items.Item(i))
' Vérify existence of directory
If D.Exists Then
If SD.Exists Then
'Do nothing because the subdirectory already exists in the parent folder
Else
'Create the sub-directory with the name from the listbox
D.CreateSubdirectory(lstbEleves.Items.Item(i).ToString)
End If
End If
Next
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Exclamation, Me.Text)
End Try
End Sub
I don't why it doesn't work.
If i don't put any if the folders are created..... but there no test!
can you help
thanks

what about the use of DirectoryInfo.GetDirectories and compare if any items
in your list is in existence?
