Represents a set of access rights to be audited for a user or group. This class cannot be inherited.
Assembly: System (in System.dll)
Thetype exposes the following members.
|AccessMask||Gets the access mask for this rule. (Inherited from AuthorizationRule.)|
|AuditFlags||Gets the audit flags for this audit rule. (Inherited from AuditRule.)|
|IdentityReference||Gets the IdentityReference to which this rule applies. (Inherited from AuthorizationRule.)|
|InheritanceFlags||Gets the value of flags that determine how this rule is inherited by child objects. (Inherited from AuthorizationRule.)|
|IsInherited||Gets a value indicating whether this rule is explicitly set or is inherited from a parent container object. (Inherited from AuthorizationRule.)|
|PropagationFlags||Gets the value of the propagation flags, which determine how inheritance of this rule is propagated to child objects. This property is significant only when the value of the InheritanceFlags enumeration is not None. (Inherited from AuthorizationRule.)|
|SemaphoreRights||Gets the access rights affected by the audit rule.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class is one of a set of classes that the .NET Framework provides for managing Windows access control security on named system semaphores. For an overview of these classes and their relationship to the underlying Windows access control structures, see SemaphoreSecurity.
Windows access control security is meaningful only for named system semaphores. If a Semaphore object represents a local semaphore, access control is irrelevant.
To get a list of the audit rules currently applied to a named semaphore, use the Semaphore.GetAccessControl method to get a SemaphoreSecurity object, and then use its GetAuditRules method to obtain a collection of objects.
objects do not map one-to-one with access control entries in the underlying discretionary access control list (DACL). When you get the set of all audit rules for a semaphore, the set contains the minimum number of rules currently required to express all the access control entries.
The underlying access control entries change as you apply and remove rules. The information in rules is merged if possible, to maintain the smallest number of access control entries. Thus, when you read the current list of rules, it might not look exactly like the list of all the rules you have added.
Use objects to specify access rights to be audited for a user or group. To apply a rule to a named system semaphore, use the Semaphore.GetAccessControl method to get the SemaphoreSecurity object. Modify the SemaphoreSecurity object by using its methods to add the rule, and then use the Semaphore.SetAccessControl method to reattach the security object.
Changes you make to a SemaphoreSecurity object do not affect the access levels of the named semaphore until you call the Semaphore.SetAccessControl method to assign the altered security object to the named semaphore.
objects are immutable. Security for a semaphore is modified using the methods of the SemaphoreSecurity class to add or remove rules; as you do this, the underlying access control entries are modified.
Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
