Açıklamalar

Dikkat

Kod Erişim Güvenliği (CAS), .NET Framework ve .NET'in tüm sürümlerinde kullanım dışı bırakılmıştır. .NET'in son sürümleri CAS ek açıklamalarını dikkate almaz ve CAS ile ilgili API'ler kullanılıyorsa hata üretir. Geliştiriciler, güvenlik görevlerini yerine getirmek için alternatif yöntemler aramalıdır.

Ortak dil çalışma zamanındaki izinler, belirtilen kaynaklar için güvenli hale getirilebilen işlem kümelerini açıklayan nesnelerdir. İzin nesnesi, güvenlik denetimine tabi işlemleri veya erişimi açıklar; erişimi veya işlemleri gerçekleştirme hakkını temsil etmez. İzinler hem uygulama kodu hem de .NET Framework güvenlik sistemi tarafından aşağıdaki yollarla kullanılır:

  • Kod, çalıştırmak için ihtiyaç duyduğu izinleri istiyor.

  • Güvenlik sistemi ilkesi, kod çalıştırılması için izinler verir.

  • Kod, çağırma kodunun bir izne sahip olduğunu gerektirir.

  • Kod, assert/deny/permit-only kullanarak güvenlik yığınını geçersiz kılar.

Not

Yeni bir izin yazarsanız, sınıfınızda bu arabirimi uygulamanız gerekir.

Önemli

Bir izne birden çok iş parçacığı tarafından erişilebilir. Bu arabirimi uygularken , , IntersectUnionve Copy yöntem uygulamalarının IsSubsetOfiş parçacığı güvenli olduğunu garanti etmeniz gerekir.

Yöntemler

Copy()
Geçersiz.

Geçerli iznin özdeş bir kopyasını oluşturur ve döndürür.

Demand()
Geçersiz.

Güvenlik gereksinimi karşılanmazsa çalışma zamanında bir SecurityException oluşturur.

FromXml(SecurityElement)
Geçersiz.

Xml kodlamasından belirtilen duruma sahip bir güvenlik nesnesini yeniden oluşturur.

(Devralındığı yer: ISecurityEncodable)
Intersect(IPermission)
Geçersiz.

Geçerli iznin ve belirtilen iznin kesişimi olan bir izin oluşturur ve döndürür.

IsSubsetOf(IPermission)
Geçersiz.

Geçerli iznin belirtilen iznin bir alt kümesi olup olmadığını belirler.

ToXml()
Geçersiz.

Güvenlik nesnesinin ve geçerli durumunun XML kodlamasını oluşturur.

(Devralındığı yer: ISecurityEncodable)
Union(IPermission)
Geçersiz.

Geçerli iznin ve belirtilen iznin birleşimi olan bir izin oluşturur.

Şunlara uygulanır
