Valeur de propriété

A TimeSpan object that specifies the expiration age for notifications from the notification class.

Notes

If no ExpirationAge value is specified, notifications never expire. Notification Services continues to attempt delivery of all notifications until the retry schedule is exhausted.

During delivery, Notification Services ignores any notifications that have expired per the ExpirationAge value.

To remove the expiration age value from a deployed application, you must set the value to TimeSpan.Zero.

Exemple

The following examples show how to set the expiration age for notifications generated for a notification class:

flightNotifications.ExpirationAge = new TimeSpan(2, 0, 0);

flightNotifications.ExpirationAge = New TimeSpan(2, 0, 0)
