示例

The following examples show how to use the FieldTypeMods method to get the field modifiers of an event class field by providing the field ordinal.

These examples use the Microsoft.SqlServer.NotificationServices namespace.

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"
Dim eventClassName As String = "MyEventClassName"
Dim fieldOrdinal As Integer = 0

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

'Use the FieldTypeMods method to get a field's modifiers.
Dim fieldTypeMods As String = _
    myEventClass.FieldTypeMods(fieldOrdinal)

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string eventClassName = "MyEventClassName";
int fieldOrdinal = 0;

//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 EventClassEnumeration.Item 
//to return an EventClass object.
EventClass myEventClass = 
    myEventClassEnumeration[eventClassName];

//Use the FieldTypeMods method to get a field's modifiers.
string fieldTypeMods = 
    myEventClass.FieldTypeMods(fieldOrdinal);
