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.


SqlChangeMonitor(SqlDependency) SqlChangeMonitor(SqlDependency) SqlChangeMonitor(SqlDependency) SqlChangeMonitor(SqlDependency)

Initializes a new instance of the SqlChangeMonitor class.


HasChanged HasChanged HasChanged HasChanged

Gets a value that indicates that the state that is monitored by the ChangeMonitor class has changed.

(Inherited from ChangeMonitor)
IsDisposed IsDisposed IsDisposed IsDisposed

Gets a value that indicates that the derived instance of a ChangeMonitor class is disposed.

(Inherited from ChangeMonitor)
UniqueId UniqueId UniqueId UniqueId

Gets an identifier for a SqlChangeMonitor instance.


Dispose() Dispose() Dispose() Dispose()

Releases all resources that are used by the current instance of the ChangeMonitor class.

(Inherited from ChangeMonitor)
Dispose(Boolean) Dispose(Boolean) Dispose(Boolean) 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.

NotifyOnChanged(OnChangedCallback) NotifyOnChanged(OnChangedCallback) NotifyOnChanged(OnChangedCallback) NotifyOnChanged(OnChangedCallback)

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(Object) OnChanged(Object) OnChanged(Object) OnChanged(Object)

Called by derived classes to raise the event when a dependency changes.
