備註

Some protocol use protocol headers, such as the To header field for the Simple Mail Transfer Protocol (SMTP) delivery protocol. A ProtocolField object represents one protocol field for a delivery protocol.

A ProtocolField has a name and either a SqlExpression or a FieldReference. The FieldName and SqlExpression combination enables you to use a Transact-SQL expression to define the protocol field value. The FieldName and FieldReference combination enables you to use a value from a notification field as the protocol field value.

範例

The following examples show how to define a protocol field and add it to a protocol definition in a notification class:

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)
