備註

When an OrCondition tree is added to a rule, the tree evaluates to true if any child conditions is true.

You must specify at least one child condition using the OrCondition constructor or the inherited Children property.

範例

The following example shows how to use an OrCondition object to define a Condition for a Notification Services subscription. This condition consists of two SimpleLeafCondition objects. If either SimpleLeafCondition object evaluates to true, the OrCondition is true.

// Create the NSInstance object.
NSInstance testInstance =
    new NSInstance("InventoryTrackerInstance");

// Create the NSApplication object.
NSApplication testApplication =
    new NSApplication(testInstance, "InventoryTracker");

// Define subscription properties
Subscription s = new Subscription(testApplication, "InventoryTrackerSubscriptions");
s.SubscriberId = "TestUser1";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s["DeviceName"] = "Work e-mail";
s["SubscriberLocale"] = "en-US";

// Define OrCondition
s.Condition = new OrCondition(
    new SimpleLeafCondition(new FieldValue("Quantity"),
        SimpleOperator.GreaterThanOrEqualTo,
        500),
    new SimpleLeafCondition(new FieldValue("Quantity"),
        SimpleOperator.LessThanOrEqualTo,
        35)
);

// Add subscription
s.Add();

' Create the NSInstance object.
Dim testInstance As New NSInstance("InventoryTrackerInstance")
 
' Create the NSApplication object.
Dim testApplication As _
    New NSApplication(testInstance, "InventoryTracker")
 
' Define subscription properties
Dim s As New Subscription( _
    testApplication, "InventoryTrackerSubscriptions")
s.SubscriberId = "TestUser1"
s.Enabled = True
s.RuleName = "InventoryTrackerRule"
s("DeviceName") = "Work e-mail"
s("SubscriberLocale") = "en-US"
 
' Define OrCondition
s.Condition = New OrCondition( _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.GreaterThanOrEqualTo, _
        500), _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.LessThanOrEqualTo, _
        35))
 
' Add subscription
s.Add()
