Parametri

eventField
The EventField to add to the collection.

Osservazioni

Each EventField must have a unique name.

Using this method, you add each EventField to the end of the collection. The order of the fields is maintained.

If you add event fields to an application after deploying the application, you must Update the instance to apply the changes.

Esempio

The following examples show how to define an event field that cannot be null and then add it to the end of the collection of event fields:

// Add an orgin field to the end of the field collection
EventField eventOrgin = 
    new EventField(flightEvents, "LeavingFrom");
eventOrgin.Type = "nvarchar(6)";
eventOrgin.TypeModifier = "not null";
flightEvents.EventFields.Add(eventOrgin);

' Add an orgin field to the end of the field collection.
Dim eventOrgin As EventField = _
    New EventField(flightEvents, "LeavingFrom")
eventOrgin.Type = "nvarchar(6)"
eventOrgin.TypeModifier = "not null"
flightEvents.EventFields.Add(eventOrgin)
