Typically, after creating a new FolderBrowserDialog, you set the RootFolder to the location from which to start browsing. Optionally, you can set the SelectedPath to an absolute path of a subfolder of RootFolder that will initially be selected. You can also optionally set the Description property to provide additional instructions to the user. Finally, call the ShowDialog method to display the dialog box to the user. When the dialog box is closed and the dialog box result from ShowDialog is DialogResult.OK, the SelectedPath will be a string containing the path to the selected folder.
