• W Kod powłoki pakietu interfejsu API systemu Windows https://www.nuget.org/packages ... Shell :

  using Microsoft.WindowsAPICodePack.Dialogs;...var dialog = new CommonOpenFileDialog();dialog.IsFolderPicker = true;CommonFileDialogResult result = dialog.ShowDialog();

  Zauważ, że to okno dialogowe nie jest dostępne w systemach operacyjnych starszych niż Windows Vista, więc najpierw sprawdź

• Przycisk potwierdzenia nadal mówi „Zapisz” zamiast czegoś w rodzaju „Wybierz katalog”, ale w przypadku takim jak kopalnie I „Zapisz”, wybór katalogu nadal działa ...
• Pole wejściowe nadal zawiera tekst „Nazwa pliku” zamiast „nazwa katalogu”, ale możemy powiedzieć, że katalog jest typem pliku ...
• Jest też menu „Zapisz jako typ”, ale jego wartość to „Katalog (* .this.directory)” i użytkownik nie może go zmienić na coś innego, działa dla mnie ...
