SqlNotificationRequest

Remarks

This class provides low-level access to the query notification services exposed by SQL Server 2005. For most applications the SqlDependency class provides a simpler way of using query notifications. However, if you need fine control over when notifications occur, or you need to customize the message data returned as part of a notification, the SqlNotificationRequest class is the one to use.

Constructors

SqlNotificationRequest()	Creates a new instance of the SqlNotificationRequest class with default values.
SqlNotificationRequest(String, String, Int32)	Creates a new instance of the SqlNotificationRequest class with a user-defined string that identifies a particular notification request, the name of a predefined SQL Server 2005 Service Broker service name, and the time-out period, measured in seconds.

Properties

Options	Gets or sets the SQL Server Service Broker service name where notification messages are posted.
Timeout	Gets or sets a value that specifies how long SQL Server waits for a change to occur before the operation times out.
UserData	Gets or sets an application-specific identifier for this notification.
