Замечания

Use this method to return an IEnumerator interface that allows you to iterate through the event classes in an EventClassEnumeration object. An initialized EventClassEnumeration object represents the collection of event classes in a specified Notification Services application.

Пример

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

These examples use the Microsoft.SqlServer.NotificationServices namespace.

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 an EventClassEnumeration object.
Dim myEventClassEnumeration As _
    New EventClassEnumeration(myApplication)

'Iterate through the event classes.
Dim eventClass As EventClass
For Each eventClass In myEventClassEnumeration
    Console.WriteLine("Event Class Name: {0}", _
    eventClass.EventClassName)
Next eventClass

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 an EventClassEnumeration object.
EventClassEnumeration myEventClassEnumeration = 
    new EventClassEnumeration(myApplication);

//Iterate through the event classes.
foreach (EventClass eventClass in myEventClassEnumeration)
{
    Console.WriteLine("Event Class Name: {0}", 
        eventClass.EventClassName);
}
