Valor de propiedad

A ProtocolFieldCollection object that represents the protocol header fields for the delivery protocol.

Notas

Header fields are technically optional, but may be required by specific delivery protocols. For example, the built-in Simple Mail Transfer Protocol (SMTP) delivery protocol requires Subject, From, and To fields.

If you update the fields, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the Microsoft SQL Server tables used by this notification class. Any data existing in the existing notification class tables is permanently deleted.

Ejemplo

The following examples show how add a protocol field that references a notification field. The field is added at a specific position in the protocol field collection:

ProtocolField fileProtocolField3 = 
    new ProtocolField(fileProtocol, "Price");
fileProtocolField3.FieldReference = "FormattedPrice";
fileProtocol.ProtocolFields.Add(fileProtocolField3, 1);

Dim fileProtocolField3 As ProtocolField = _
    New ProtocolField(fileProtocol, "Price")
fileProtocolField3.FieldReference = "FormattedPrice"
fileProtocol.ProtocolFields.Add(fileProtocolField3, 1)

The following examples show how add a protocol field that uses an expression to compute the value. The field is added to the end of the collection:

ProtocolField smtpProtocolField1 = 
    new ProtocolField(smtpProtocol, "Subject");
smtpProtocolField1.SqlExpression = 
    "'Flight notification: '+CONVERT (NVARCHAR(30), GETDATE())";
smtpProtocol.ProtocolFields.Add(smtpProtocolField1);

Dim smtpProtocolField1 As ProtocolField = _
    New ProtocolField(smtpProtocol, "Subject")
smtpProtocolField1.SqlExpression = _
    "'Flight notification: '+CONVERT (NVARCHAR(30), GETDATE())"
smtpProtocol.ProtocolFields.Add(smtpProtocolField1)
