Он работает, но так не пойдет. Нужно не вручную текст вбивать или вставлять в RichTextBox,а так сделать, чтобы можно было взять много файлов (от 500 вроде) из одной папки, подписать их с ЭЦП и переложить в другую.
Думал с помощью Openfiledialog & SaveFileDialog делать, но, кажется, что так неправильно... Но пока что хотелось бы, чтобы хоть так работало.

Тут подскажите,пожалуйста, как сделать так, если это возможно , чтобы без ричбоксов: открылся диалог, выбрали файлы, они подписались, проверились, открылся другой диалог, их сохранили.
Заранее большое спасибо! |
