傳回值

An IEnumerator interface for the SubscriptionEnumeration object.

備註

Use this method to return an IEnumerator interface that allows you to iterate through the subscriptions in a SubscriptionEnumeration object. An initialized SubscriptionEnumeration object represents the collection of subscriptions of a particular subscription class for one subscriber in a specified Notification Services application.

範例

The following examples show how to use a SubscriptionEnumeration object to iterate through a set of subscriptions. The GetEnumerator method makes the For Each and foreach statements possible:

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"
Dim subscriptionClassName As String = "MySubscriptionClassName"
Dim subscriberId As String = "MySubscriberID"

'Create an NSInstance object.
Dim myInstance As New NSInstance(instanceName)

'Create an NSApplication object.
Dim myApplication As New NSApplication(myInstance, applicationName)

'Create a SubscriptionEnumeration object.
Dim mySubscriptionEnumeration As _
    New SubscriptionEnumeration(myApplication, _
    subscriptionClassName, subscriberId)

'Iterate through the subscriptions.
Dim subscription As Subscription
For Each subscription In mySubscriptionEnumeration
    Console.WriteLine("Subscription ID: {0}", _
    subscription.SubscriptionId)
Next subscription

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string subscriptionClassName = "MySubscriptionClassName";
string subscriberId = "MySubscriberID";

//Create an NSInstance object.
NSInstance myInstance = new NSInstance(instanceName);

//Create an NSApplication object.
NSApplication myApplication = 
    new NSApplication(myInstance, applicationName);

//Create a SubscriptionEnumeration object.
SubscriptionEnumeration mySubscriptionEnumeration = 
    new SubscriptionEnumeration(myApplication, 
    subscriptionClassName, subscriberId);

//Iterate through the subscriptions.
foreach (Subscription subscription 
    in mySubscriptionEnumeration)
{
    Console.WriteLine("Subscription ID: {0}", 
        subscription.SubscriptionId);
}
