CommonAcl CommonAcl CommonAcl CommonAcl Class

Definition

Represents an access control list (ACL) and is the base class for the DiscretionaryAcl and SystemAcl classes.

Remarks

Canonical order is maintained according to the following algorithm:

  • Explicit ACEs take precedence over inherited ACEs; this rule applies to both DACLs and SACLs.

  • In DACLs, among the explicit ACEs, ACEs that deny access take precedence over ACEs that allow access. For directory object ACLs, the nonobject ACEs come before object ACEs.

  • All common ACEs take precedence over noncommon ACEs.

  • Inherited ACEs maintain their relative order after canonicity.

  • Unrecognized and custom ACEs are disallowed in both DACLs and SACLs.

  • Within contiguous ranges (explicit AccessDenied and AccessAllowed ACEs on DACLs, all explicit ACEs on SACLs), the ACEs are sorted by using the CompareTo methods of the SecurityIdentifier objects associated with the ACEs.

Adjacent ACEs are combined, if appropriate. This reduces the size of the ACL without affecting the access control semantics it grants.

Properties

BinaryLength BinaryLength BinaryLength BinaryLength

Gets the length, in bytes, of the binary representation of the current CommonAcl object. This length should be used before marshaling the access control list (ACL) into a binary array by using the GetBinaryForm(Byte[], Int32) method.

Count Count Count Count

Gets the number of access control entries (ACEs) in the current CommonAcl object.

IsCanonical IsCanonical IsCanonical IsCanonical

Gets a Boolean value that specifies whether the access control entries (ACEs) in the current CommonAcl object are in canonical order.

IsContainer IsContainer IsContainer IsContainer

Sets whether the CommonAcl object is a container.

IsDS IsDS IsDS IsDS

Sets whether the current CommonAcl object is a directory object access control list (ACL).

IsSynchronized IsSynchronized IsSynchronized IsSynchronized

This property is always set to false. It is implemented only because it is required for the implementation of the ICollection interface.

(Inherited from GenericAcl)
Item[Int32] Item[Int32] Item[Int32] Item[Int32]

Gets or sets the CommonAce at the specified index.

Revision Revision Revision Revision

Gets the revision level of the CommonAcl.

SyncRoot SyncRoot SyncRoot SyncRoot

This property always returns null. It is implemented only because it is required for the implementation of the ICollection interface.

(Inherited from Object)
Purge(SecurityIdentifier) Purge(SecurityIdentifier) Purge(SecurityIdentifier) Purge(SecurityIdentifier)

Removes all access control entries (ACEs) contained by this CommonAcl object that are associated with the specified SecurityIdentifier object.

RemoveInheritedAces() RemoveInheritedAces() RemoveInheritedAces() RemoveInheritedAces()

Removes all inherited access control entries (ACEs) from this CommonAcl object.
