Açıklamalar

sınıfı FileSystemAccessRule , bir kullanıcı hesabını, sağlanması gereken erişim türünü (okuma, yazma vb.) ve bu haka izin verilip verilmeyeceğini belirten temel erişim denetimi girişinin (ACE) soyutlamasını temsil eder. Bu sınıf, erişim kurallarının alt nesnelere nasıl yayılacağını da belirtebilir.

Yeni bir erişim kuralı oluşturmak için sınıfını FileSystemAccessRule kullanın. veya DirectorySecurity sınıfını kullanarak FileSecurity kuralı kalıcı hale ekleyebilirsiniz.
