You must specify values for the Result and Condition properties.

Ejemplo

The following example shows how to specify three properties: Few, Some, and Alot. Subscribers can use these properties when defining subscriptions.

// Define a new property that defines "Few," "Some," and "Alot"
// of inventory. 
PropertyRule quantityCategory = new PropertyRule(
    new ViewInputType(eventView),
    new PropertyStatement(new SimpleLeafCondition(
        new FieldValue("Quantity"),
        SimpleOperator.LessThan, 100), "Few"),
    new PropertyStatement(new BetweenLeafCondition(
        new FieldValue("Quantity"), 100, 200), "Some"),
    new PropertyStatement(new SimpleLeafCondition(
            new FieldValue("Quantity"),
            SimpleOperator.GreaterThan, 200),
        "Alot"));

// Create subscription and define basic properties.
s = new Subscription(nsApplication, subscriptionClassName);
s.SubscriberId = "Scott";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s.SetFieldValue("DeviceName", "myDevice");
s.SetFieldValue("SubscriberLocale", "en-us");


// Use the new property to return only products with "few" remaining
// in inventory. Note that the category definition can be reused.
s.Condition = new SimpleLeafCondition(
    new RuleValue(quantityCategory),
    SimpleOperator.Equals,
    "Few");

// Add subscription.
s.Add();
