A TimeSpan object that specifies the action timeout for the event rule.

Osservazioni

When using the default constructor, you must set this property. When using the SubscriptionEventRule(SubscriptionClass,String) constructor, the default time-out is 30 minutes.

If an action does not complete in the time specified, the action is canceled and an error is recorded in the Microsoft Windows Application log.

Esempio

The following examples show how to define an event rule and then add it to a subscription class:

// Add a rule to generate basic event-triggered notifications
SubscriptionEventRule flightEventRule = 
    new SubscriptionEventRule(flightSubscriptions, 
    "FlightSubscriptionsEventRule");
flightEventRule.Action = "INSERT INTO FlightNotifications " + 
    "(SubscriberId, DeviceName, SubscriberLocale, " + 
    "LeavingFrom, GoingTo, Price) " + 
    "SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " + 
    "E.LeavingFrom, E.GoingTo, E.Price " + 
    "FROM FlightEvents E, FlightSubscriptions S " + 
    "WHERE     E.LeavingFrom     = S.LeavingFrom " + 
    "AND    E.GoingTo    = S.GoingTo " + 
    "AND    E.Price    < S.Price";
flightEventRule.ActionTimeout = new TimeSpan(0, 1, 0);
flightEventRule.EventClassName = "FlightEvents";
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule);

' Add a rule to generate basic event-triggered notifications
Dim flightEventRule As SubscriptionEventRule = _
    New SubscriptionEventRule(flightSubscriptions, _
        "FlightSubscriptionsEventRule")
flightEventRule.Action = _
    "INSERT INTO FlightNotifications " + _
    "(SubscriberId, DeviceName, SubscriberLocale, " + _
    "LeavingFrom, GoingTo, Price) " + _
    "SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " + _
    "E.LeavingFrom, E.GoingTo, E.Price " + _
    "FROM FlightEvents E, FlightSubscriptions S " + _
    "WHERE E.LeavingFrom = S.LeavingFrom " + _
    "AND E.GoingTo = S.GoingTo " + _
    "AND E.Price < S.Price"
flightEventRule.ActionTimeout = New TimeSpan(0, 1, 0)
flightEventRule.EventClassName = "FlightEvents"
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule)
