Esempio

The following examples show how to use the FieldType method to get the data type 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 FieldType method to get a field data type.
Dim fieldType As String = myEventClass.FieldType(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 FieldType method to get a field data type.
string fieldType = myEventClass.FieldType(fieldOrdinal);
