示例

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"
Dim notificationClassName As String = "MyNotificationClassName"
Dim fieldName As String = "MyNotificationFieldName"

'Create an NSInstance object.

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

'Create a NotificationClassEnumeration object.
Dim myNotificationClassEnumeration As _
    New NotificationClassEnumeration(myApplication)

'Use the NotificationClassEnumeration.Item 
'to return a NotificationClass object.
Dim myNotificationClass As NotificationClass = _
    myNotificationClassEnumeration(notificationClassName)

'Use the NotificationFieldOrdinal method to get a field ordinal.
Dim fieldOrdinal As Integer = _
    myNotificationClass.NotificationFieldOrdinal(fieldName)

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string notificationClassName = "MyNotificationClassName";
string fieldName = "MyComputedFieldName";

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

//Create an NSApplication object.
NSApplication myApplication =

//Use the NotificationClassEnumeration.Item 
//to return a NotificationClass object.
NotificationClass myNotificationClass = 
    myNotificationClassEnumeration[notificationClassName];

//Use the ComputedFieldOrdinal method to get a field ordinal.
int fieldOrdinal = myNotificationClass.ComputedFieldOrdinal(
    fieldName);
