Is it possible to use the OpenFileDialog class select a file OR folder? It appears only to allow the selection of a file, if you select a folder and then choose open it will navigate to that folder.
If the OpenFileDialog can not be used for this is there another object I should be using?
EDIT: The scenario is that I have a tool that can upload one...many files or folders. I need to be able to provide a dialog like the OpenFileDialog that allows a user to select a file, folder, or a combination of. I know about the FolderBrowseDialog and that is not the answer in this case.
This is the solution I have been looking for, this article provides code and describes how to create a dialog that meets my needs.
Yes, you can use OpenFileDialog to select a folder. Here is an article in CodeProject that demonstrated a way to do it (http://www.codeproject.com/KB/dialog/OpenFileOrFolderDialog.aspx).
In my experience in .NET, I would have to say no, sorry for the negative and short answer, but I really don't think there is
If you have time, you can create your own pretty easily by using the System.Windows.Forms.TreeView Class. Each node can have a checkbox, so If you populate the treeview (onexpand) you can let the user select the files/directories he wants to upload.
This should get you started on populating the treeview with directories, the job to also add files in the treeview should not be that hard:

No: the OpenFileDialog is just for opening files. Anyway there is a FolderBrowserDialog you can use for that.
[Edit] Answered too fast: the Edit from the questioner was afterwards.
I'd suggest taking a look at the Ookii Dialogs libraries which have an implementation of a folder browser dialog for Windows Forms and WPF respectively:
Ookii.Dialogs.Wpf
Ookii.Dialogs.WinForms
