示例

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

These examples use the Microsoft.SqlServer.NotificationServices namespace.

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

'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 FieldOrdinal method to get a field ordinal.
Dim fieldOrdinal As Integer = myEventClass.FieldOrdinal(fieldName)

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

//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 FieldOrdinal method to get a field ordinal.
int fieldOrdinal = myEventClass.FieldOrdinal(fieldName);
