Предотвратить класс wnetaddconnection2, который позволяет запрещенному пользователю получить доступ к общей папке ⇐ C#

[Anonymous]

Я разработал приложение C# Windows. ОС - это Windows 7

Требование: - это доступ к сетевой общей папке «Тест» с использованием кода с учетными данными с использованием wnetaddconnection2 . SET. не имеет разрешения. < /p>

Но проблема - это класс wnetaddConnection2 позволяет «пользователю a» успешно устанавливать сетевое соединение.
infect «wnetaddConnection2 позволяет всем пользователям из домена». Класс проверяет права доступа. < /Strong> < /p>

код < /p>
