Poznámky

Upozornění

Zabezpečení přístupu kódu (CAS) bylo zastaralé ve všech verzích rozhraní .NET Framework a .NET. Nedávné verze rozhraní .NET nedodržují poznámky CAS a při použití rozhraní API souvisejících s cas vytvářejí chyby. Vývojáři by měli hledat alternativní způsoby provádění úloh zabezpečení.

Oprávnění v modulu CLR (Common Language Runtime) jsou objekty, které popisují sady operací, které lze zabezpečit pro zadané prostředky. Objekt oprávnění popisuje operace nebo přístup, které podléhají řízení zabezpečení; nepředstavuje přístup ani právo provádět operace. Oprávnění se používají v kódu aplikace i v systému zabezpečení rozhraní .NET Framework následujícími způsoby:

• Kód si vyžádá oprávnění, která potřebuje ke spuštění.

• Zásady zabezpečení systému udělují oprávnění ke kódu, aby se mohl spustit.

• Kód vyžaduje, aby volající kód měl oprávnění.

• Kód přepíše zásobník zabezpečení pomocí příkazu assert/deny/permit-only.

Poznámka

Pokud napíšete nové oprávnění, musíte implementovat toto rozhraní ve vaší třídě.

Důležité

K oprávněním může přistupovat více vláken. Při implementaci tohoto rozhraní musíte zaručit, že IsSubsetOfimplementace metod , Intersect, Uniona Copy jsou bezpečné z více vláken.

Metody

Copy()	Zastaralé. Vytvoří a vrátí identickou kopii aktuálního oprávnění.
Demand()	Zastaralé. Vyvolá za SecurityException běhu, pokud není splněn požadavek na zabezpečení.
FromXml(SecurityElement)	Zastaralé. Rekonstruuje objekt zabezpečení se zadaným stavem z kódování XML. (Zděděno od ISecurityEncodable)
Intersect(IPermission)	Zastaralé. Vytvoří a vrátí oprávnění, které je průsečíkem aktuálního oprávnění a zadaného oprávnění.
IsSubsetOf(IPermission)	Zastaralé. Určuje, zda je aktuální oprávnění podmnožinou zadaného oprávnění.
ToXml()	Zastaralé. Vytvoří kódování XML objektu zabezpečení a jeho aktuálního stavu. (Zděděno od ISecurityEncodable)
Union(IPermission)	Zastaralé. Vytvoří oprávnění, které je sjednocením aktuálního a zadaného oprávnění.
