备注

Use the MergeSynchronizationAgent object returned by the SynchronizationAgent property to start the Merge Agent synchronously.

If the pull subscription is created with a value of false for CreateSyncAgentByDefault, the default, a Merge Agent job for the subscription is not created and calling SynchronizeWithJob will cause an exception.

Call the StopSynchronizationJob method to stop the job if it is currently running.

The job is not able to start if the Microsoft SQL Server Agent Service is not running. Also if a snapshot is not generated, running the agent job may not synchronize the subscription.

If you have set additional properties on this instance of MergePullSubscription, call CommitPropertyChanges before calling SynchronizeWithJob.

The SynchronizeWithJob method can only be called by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.
