При создании программы синхронизации файлов в C # я пытался создать метод copy в LocalFileItem классе, который использует метод System.IO.File.Copy(destination.Path, Path, true), где Path - это string.
После выполнения этого кода с назначением. Path = "C:\\Test2" и this.Path = "C:\\Test\\F1.txt" Я получаю исключение о том, что у меня нет необходимых прав доступа к файлам для выполнения этой операции на C: \ Test , но C: \ Test принадлежит сам (текущий пользователь) .
Кто-нибудь знает, что происходит или как обойти это?
Вот исходный код, завершенный.
