SqlChangeMonitor Class
Visual Studio 2010
Provides change monitoring for SQL Server databases. This class cannot be inherited.
Assembly: System.Runtime.Caching (in System.Runtime.Caching.dll)
The SqlChangeMonitor type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | HasChanged | Gets a value that indicates that the state that is monitored by the ChangeMonitor class has changed. (Inherited from ChangeMonitor.) |
![]() | IsDisposed | Gets a value that indicates that the derived instance of a ChangeMonitor class is disposed. (Inherited from ChangeMonitor.) |
![]() | UniqueId | Gets an identifier for a SqlChangeMonitor instance. (Overrides ChangeMonitor::UniqueId.) |
| Name | Description | |
|---|---|---|
![]() | Dispose() | Releases all resources that are used by the current instance of the ChangeMonitor class. (Inherited from ChangeMonitor.) |
![]() | Dispose(Boolean) | Releases all managed and unmanaged resources and any references to the ChangeMonitor instance. This overload must be implemented by derived change-monitor classes. (Inherited from ChangeMonitor.) |
![]() | 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.) |
![]() | InitializationComplete | Called from the constructor of derived classes to indicate that initialization is finished. (Inherited from ChangeMonitor.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | NotifyOnChanged | Called by Cache implementers to register a callback and notify an ObjectCache instance through the OnChangedCallback delegate when a dependency has changed. (Inherited from ChangeMonitor.) |
![]() | OnChanged | Called by derived classes to raise the event when a dependency changes. (Inherited from ChangeMonitor.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The SqlChangeMonitor class wraps the ADO.NET SqlDependency class and adds change monitoring for SQL Server-based dependencies. Therefore, the SqlChangeMonitor class serves as a bridge between the ADO.NET SqlDependency object and the System.Runtime.Caching namespace.
