Notes
A SubscriptionField object defines a single column in the subscription table in the application database. This table stores subscription data produced by your subscription management interface.
Notification Services automatically adds SubscriberID, Created, Updated, and Enabled fields to the subscription class schema.
If you add or delete a field, updating the application re-creates the subscription class to which it corresponds. Notification Services renames the existing subscription tables by appending Old to the table name and then creates new tables. Existing subscription table indexes are left unchanged.
If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see Mise à jour d'une application.

Exemple
The following examples show how to define a subscription field and add it to the subscription schema:
// Define a SubscriberLocale field that cannot be NULL
// Add the field to the end of the field collection
SubscriptionField subLocale =
new SubscriptionField(flightSubscriptions, "SubscriberLocale");
subLocale.Type = "nvarchar(10)";
subLocale.TypeModifier = "not null";
flightSubscriptions.SubscriptionFields.Add(subLocale);
' Define a SubscriberLocale field that cannot be NULL
' Add the field to the end of the field collection
Dim subLocale As SubscriptionField = _
New SubscriptionField(flightSubscriptions, _
"SubscriberLocale")
subLocale.Type = "nvarchar(10)"
subLocale.TypeModifier = "not null"
flightSubscriptions.SubscriptionFields.Add(subLocale)
