Remarks

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.

Constructors

SqlChangeMonitor(SqlDependency)

Initializes a new instance of the SqlChangeMonitor class.

Properties

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.

Methods

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)
GetHashCode()	Serves as the default hash function. (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(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)	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)
