An initialized SubscriptionClassEnumeration object represents the collection of subscription classes in a specified Notification Services application.

示例

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

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"

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

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

'Create a SubscriptionClassEnumeration object.
Dim mySubscriptionClassEnumeration As _
    New SubscriptionClassEnumeration(myApplication)

'Iterate through the subscription classes.
Dim subscriptionClass As SubscriptionClass
For Each subscriptionClass In mySubscriptionClassEnumeration
    Console.WriteLine("Subscription Class Name: {0}", _
    subscriptionClass.SubscriptionClassName)
Next subscriptionClass

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";

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

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

//Create a SubscriptionClassEnumeration object.
SubscriptionClassEnumeration mySubscriptionClassEnumeration = 
    new SubscriptionClassEnumeration(myApplication);

//Iterate through the subscription classes.
foreach (SubscriptionClass subscriptionClass 
    in mySubscriptionClassEnumeration)
{
    Console.WriteLine("Subscription Class Name: {0}", 
        subscriptionClass.SubscriptionClassName);
}
