声明
Public Class AndCondition
    Inherits ConditionTree

public class AndCondition : ConditionTree

public ref class AndCondition : public ConditionTree

public class AndCondition extends ConditionTree

public class AndCondition extends ConditionTree

备注

When an AndCondition tree is added to a rule, the tree evaluates to true only if all child conditions are also true.

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

示例

The following example shows how to use an AndCondition object to define a Condition for a Notification Services subscription. This condition consists of three SimpleLeafCondition objects. If all SimpleLeafCondition objects evaluate to true, the AndCondition is true.

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

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

// Create Subscription object.
Subscription s = new Subscription(testApplication, 
    "InventoryTrackerSubscriptions");

// Define subscription properties
s.SubscriberId = "TestUser1";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s["DeviceName"] = "Work e-mail";
s["SubscriberLocale"] = "en-US";

// Define OrCondition
s.Condition = new AndCondition(
    new SimpleLeafCondition(new FieldValue("ProductName"),
                    SimpleOperator.Equals,
                    "Road-250 Black, 48"),
    new SimpleLeafCondition(new FieldValue("LocationName"),
                    SimpleOperator.Equals,
                    "Final Assembly"),
    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")
 
' Create Subscription object.
Dim s As New Subscription(testApplication, _
    "InventoryTrackerSubscriptions")
 
' Define subscription properties
s.SubscriberId = "TestUser1"
s.Enabled = True
s.RuleName = "InventoryTrackerRule"
s("DeviceName") = "Work e-mail"
s("SubscriberLocale") = "en-US"
 
' Define OrCondition
s.Condition = New AndCondition( _
    New SimpleLeafCondition( _
        New FieldValue("ProductName"), _
        SimpleOperator.Equals, _
        "Road-250 Black, 48"), _
    New SimpleLeafCondition( _
        New FieldValue("LocationName"), _
        SimpleOperator.Equals, _
        "Final Assembly"), _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.LessThanOrEqualTo, _
        35))
 
' Add subscription
s.Add()
