Syntax

'Declaration

    eventField As EventField, _
    insertAtPosition As Integer _
)

public void Add (
    EventField eventField,
    int insertAtPosition
)

)

public void Add (
    EventField eventField, 
    int insertAtPosition
)

public function Add (
    eventField : EventField, 
    insertAtPosition : int
)

Parameters

eventField
The EventField to add to the collection.

insertAtPosition
An Int32 value that specifies the position to add the EventField object to the collection.

Remarks

Each EventField must have a unique name.

You add each EventField at a specific position in the collection. An event field at the specified position, and all subsequent event fields, will be moved one index value higher in 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.

Example

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

// Define a price field and add it at position 1
EventField eventPrice = new EventField(flightEvents, "Price");
eventPrice.Type = "float";
flightEvents.EventFields.Add(eventPrice, 1);

' Define a price field and add it at position 1.
Dim eventPrice As EventField = _
    New EventField(flightEvents, "Price")
eventPrice.Type = "float"
flightEvents.EventFields.Add(eventPrice, 1)
