Комментарии

Скачивает указанный документ, а затем вызывает перегруженный Resolve член, который принимает тип MIME и a Stream. Если тип MIME и содержимое совпадения, ожидаемые stream ссылочным типом, содержимое stream добавляется в References свойства и Documents свойства ClientProtocol.

Применяется к

Resolve(String, Stream)

Определяет допустимость документа для ссылки.
