FolderBrowseDialog Silverlight

I have an silverlight 4 application,开发者_如何学Python and I want to upload recursively a local folder on the server. For upload files separatly, there is OpenFileDialog method, But I can not select a folder path.

Does exist an equivalent of the WPF "FolderBrowseDialog" method in silverlight ?

No. That functionality is disabled for security reasons.

See OpenFileDialog for further information.

From above link:

Silverlight does not have a browse folder dialog box and you cannot use the OpenFileDialog to just select a folder.
