Public Sub Add ( _
    eventField As EventField, _
    insertAtColumnName As String _

    string insertAtColumnName

    String insertAtColumnName

Paramètres

eventField
The EventField to add to the collection.

insertAtColumnName
A String that specifies name of the event field column before which to insert the EventField.

Notes

Each EventField must have a unique name.

You add each EventField before a named field in the collection. The event field at the specified column, and all subsequent event fields, are moved down the list of event fields.

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.

Exemple

The following examples show how to define an event field and then add it to an event class before a specific event field:

// Define a destination field and add it before the Price field
EventField eventDestination = 
    new EventField(flightEvents, "GoingTo");
eventDestination.Type = "nvarchar(6)";
flightEvents.EventFields.Add(eventDestination, "Price");

' Define a destination field and add it before the Price field.
Dim eventDestination As EventField = _
    New EventField(flightEvents, "GoingTo")
eventDestination.Type = "nvarchar(6)"
flightEvents.EventFields.Add(eventDestination, "Price")
