The ExchangeType property specifies whether data merges up to the Publisher, down to the Subscriber, or in both directions.
object.ExchangeType [= value]
|object||Expression that evaluates to a SQLMerge object.|
|value||EXCHANGE_TYPE constant that specifies the direction in which data can be merged.|
The ExchangeType property is typically used first to upload all the changes from several Subscribers to a Publisher, and then to download the changes to the Subscribers only after all the uploads have been completed.
BIDIRECTIONAL is the default. You should use a BIDIRECTIONAL synchronization unless you have a specific reason for separating the UPLOAD and DOWNLOAD phases.
