Opmerkingen

Deze constructor geeft standaarddoorgifte en overname aan. Dat is, InheritanceFlags.None en PropagationFlags.None.

Deze constructor is gelijk aan het maken van een NTAccount object door te geven identity aan de NTAccount.NTAccount(String) constructor en het zojuist gemaakte NTAccount object door te geven aan de RegistryAccessRule(IdentityReference, RegistryRights, AccessControlType) constructor.

public:
 RegistryAccessRule(System::Security::Principal::IdentityReference ^ identity, System::Security::AccessControl::RegistryRights registryRights, System::Security::AccessControl::InheritanceFlags inheritanceFlags, System::Security::AccessControl::PropagationFlags propagationFlags, System::Security::AccessControl::AccessControlType type);

Public Sub New (identity As IdentityReference, registryRights As RegistryRights, inheritanceFlags As InheritanceFlags, propagationFlags As PropagationFlags, type As AccessControlType)

Parameters

Uitzonderingen

Opmerkingen

Alle registersleutels zijn containers, dus de enige overnamevlag die zinvol is voor registersleutels is de InheritanceFlags.ContainerInherit vlag. Als deze vlag niet is opgegeven, worden de doorgiftevlagmen genegeerd en wordt alleen de directe sleutel beïnvloed. Als de vlag aanwezig is, wordt de regel doorgegeven zoals wordt weergegeven in de volgende tabel. In de tabel wordt ervan uitgegaan dat er een subsleutel S met onderliggende subsleutel CS en kleinkind subsleutel GS is. Dat wil gezegd, het pad voor de subsleutel voor kleinkind is S\CS\GS.

Het patroon voor de subsleutel voor kleinkind bepaalt alle subsleutels die zijn opgenomen in de subsleutel voor kleinkind.

Als de ContainerInherit vlag bijvoorbeeld is opgegeven en de InheritOnly doorgiftevlag is opgegeven inheritanceFlagspropagationFlags, is deze regel niet van toepassing op de onmiddellijke subsleutel, maar geldt dit voor alle onderliggende subsleutels en voor alle subsleutels die ze bevatten.

public:
 RegistryAccessRule(System::String ^ identity, System::Security::AccessControl::RegistryRights registryRights, System::Security::AccessControl::InheritanceFlags inheritanceFlags, System::Security::AccessControl::PropagationFlags propagationFlags, System::Security::AccessControl::AccessControlType type);

public RegistryAccessRule(string identity, System.Security.AccessControl.RegistryRights registryRights, System.Security.AccessControl.InheritanceFlags inheritanceFlags, System.Security.AccessControl.PropagationFlags propagationFlags, System.Security.AccessControl.AccessControlType type);

new System.Security.AccessControl.RegistryAccessRule : string * System.Security.AccessControl.RegistryRights * System.Security.AccessControl.InheritanceFlags * System.Security.AccessControl.PropagationFlags * System.Security.AccessControl.AccessControlType -> System.Security.AccessControl.RegistryAccessRule

Public Sub New (identity As String, registryRights As RegistryRights, inheritanceFlags As InheritanceFlags, propagationFlags As PropagationFlags, type As AccessControlType)

Parameters

Uitzonderingen

Voorbeelden

In het volgende codevoorbeeld ziet u toegangsregels met overname en doorgifte. In het voorbeeld wordt een RegistrySecurity object gemaakt en vervolgens twee regels gemaakt en toegevoegd met de ContainerInherit vlag. De eerste regel heeft geen doorgiftevlagmen, terwijl de tweede en NoPropagateInheritInheritOnly.

Het programma geeft de regels in het RegistrySecurity object weer en gebruikt vervolgens het RegistrySecurity object om een subsleutel te maken. Het programma maakt een onderliggende subsleutel en een subsleutel met kleinkind en geeft vervolgens de regels voor elke subsleutel weer. Ten slotte verwijdert het programma de testsleutels.
