参数

insertAtColumnName
A String value that specifies the name of a protocol field before which to add the new ProtocolField object.

备注

This method allows you to insert a protocol field at a specific position in the protocol field list. Each protocol field becomes a column in a table. Depending on how you use protocol field data, the order of the columns can be important.

If you add a field to a deployed application, updating the instance deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the tables used by the notification class. Any data existing in the existing notification class tables is permanently deleted.

示例

The following example shows how to add a protocol field before the Price field in the collection of protocol fields:

ProtocolField fileProtocolField2 = 
    new ProtocolField(fileProtocol, "GoingTo");
fileProtocolField2.FieldReference = "GoingTo";
fileProtocol.ProtocolFields.Add(fileProtocolField2, "Price");

Dim fileProtocolField2 As ProtocolField = _
    New ProtocolField(fileProtocol, "GoingTo")
fileProtocolField2.FieldReference = "GoingTo"
fileProtocol.ProtocolFields.Add(fileProtocolField2, "Price")
