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

'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)

'Use the Item property to return an EventClass object.
Dim myEventClass As EventClass = _
    myEventClassEnumeration(eventClassName)

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

//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);

//Use the Item property to return an EventClass object.
EventClass myEventClass = 
    myEventClassEnumeration[eventClassName];
