Get folder name ONLY from open file dialog /browse

using (OpenFileDialog Dialog = new OpenFileDialog { Filter = "All Files|*.*", Title = "OpenFile Dialog", RestoreDirectory = true })
            {
                if (Dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
                {
                    string Path = Dialog.FileName;
                    string FolderName = System.IO.Path.GetDirectoryName(Path);
                    System.IO.DirectoryInfo info = new System.IO.DirectoryInfo(FolderName);
                    MessageBox.Show(info.Name);
                }
            }


Why not FolderBrowserDialog Control?
