When using the default constructor, first set the Name, then the Parent and then other properties to avoid runtime exceptions. This constructor does not set any property values.

示例

The following examples show how to use this default constructor to create an event-driven rule and then add the rule to a subscription class:

// Create an event rule and set properties.
SubscriptionEventRule flightEventRule = new SubscriptionEventRule();
flightEventRule.Name = "FlightSubscriptionsEventRule";
flightEventRule.Parent = flightSubscriptions;
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, 30, 0);
flightEventRule.EventClassName = "FlightEvents";
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule);

' Create an event rule and set properties.
Dim flightEventRule As SubscriptionEventRule = _
    New SubscriptionEventRule()
flightEventRule.Name = "FlightSubscriptionsEventRule"
flightEventRule.Parent = flightSubscriptions
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, 30, 0)
flightEventRule.EventClassName = "FlightEvents"
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule)
