Namespace: System.Runtime.Caching
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.) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (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.) |
| 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.) |
| 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.
