参数

protocolField
The ProtocolField object to add to the collection.

insertAtPosition
A Int32 that specifies the zero-based position in the collection where you want to add the 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.

The protocol field currently at the position, and all subsequent protocol fields, are moved down the list.

If you add a protocol 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 at the second position in a collection of protocol fields:

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)
