Valore proprietà

A String, between 1 and 255 characters in length, that specifies the data type of the field.

Osservazioni

You must set the field type for all notification fields.

Field types must conform to SQL Server data types. The following data types are supported by Notification Services:

bigint	float	real	tinyint
binary	int	smalldatetime	uniqueidentifier
bit	money	smallint	varbinary
char	nchar	smallmoney	varchar
datetime	nvarchar	sql_variant	xml
decimal	numeric

The text, ntext, and image data types are not supported because they cannot be used as values for parameters and variables in stored procedures. In addition, the timestamp data type is not supported. For more information about SQL Server data types, see Tipi di dati (Motore di database).

If using the xml data type with the XSLT content formatter, the content formatter might attempt to transform the XML data. To preserve the XML markup, set the content formatter's DisableEscaping argument to false.

If you modify a field type, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this notification class. Any data existing in the original notification class tables is permanently deleted.

Esempio

The following examples show how to define a notification field that has a data type of float, and then add it to the collection of notification fields for a notification class:

// Define a Price field and add it at position 1 in the collection
NotificationField notificationPrice = 
    new NotificationField(flightNotifications, "Price");
notificationPrice.Type = "float";
flightNotifications.NotificationFields.Add(notificationPrice, 1);

' Define a Price field and add it at position 1 
' in the collection.
Dim notificationPrice As NotificationField = _
    New NotificationField(flightNotifications, "Price")
notificationPrice.Type = "float"
flightNotifications.NotificationFields.Add( _
    notificationPrice, 1)
