Recurse through TreeView and create folders
I want to build a function to recurse through a treeview and create each folder on a harddrive. The code is working fine so far. Once it reaches the end of a node it jumps one level deeper. But whta I am missing here is a line of code to jump back to the upper folder to continue creating the other folders.
This is what I have so far:
Private Sub RecurseNodes(ByVal col As TreeNodeCollection)
For Each tn As TreeNode In col
Console.WriteLine(drive_letter & treefix & tn.Text)
If tn.Nodes.Count > 0 Then
treefix = treefix & tn.Text & ""
RecurseNodes(tn.Nodes)
End If
Next tn
End Sub
This is what my output looks like:
E:Auftraggeber Projektname 00000
E:Auftraggeber Projektname 00000Export
E:Auftraggeber Projektname 00000Material
E:Auftraggeber Projektname 00000MaterialOriginal
E:Auftraggeber Projektname 00000MaterialTranscodiert
E:Auftraggeber Projektname 00000MaterialFootage
E:Auftraggeber Projektname 00000MaterialGFX
E:Auftraggeber Projektname 00000MaterialSFX
E:Auftraggeber Projektname 00000MaterialSprecher
E:Auftraggeber Projektname 00000MaterialProjekt
E:Auftraggeber Projektname 00000MaterialMusikand this is what the tree actually looks like:
So once the code gets to E:Auftraggeber Projektname 00000MaterialFootage, it should go back the upper folder to continue processing.
It is probably just a single line or two of code but I just can't figure it out.
Thanks for your help!

The simple solution in this case is to store the old value of the treefix variable before changing it, then revert to it after the inner RecurseNodes() call has exited:
If tn.Nodes.Count > 0 Then
Dim currentPath As String = treefix
treefix = treefix & tn.Text & ""
RecurseNodes(tn.Nodes)
treefix = currentPath
End If
Though to avoid having to use class level variables, the more sustainable solution is to just pass the current path to your method. Also, do prefer Path.Combine() when working with paths in general:
Private Sub RecurseNodes(ByVal col As TreeNodeCollection, ByVal currentDirectory As String)
For Each tn As TreeNode In col
Dim currentPath As String = Path.Combine(currentDirectory, tn.Text)
Console.WriteLine(currentPath)
If tn.Nodes.Count > 0 Then
RecurseNodes(tn.Nodes, currentPath)
End If
Next tn
End Sub
Example usage:
RecurseNodes(TreeView1.Nodes, "E:Auftraggeber Projektname 00000")

This is exactly what I needed. Passing the current path was a simple, but great idea. Thanks!
