주의

The MergeSynchronizationAgent class supports the ability to do the following replication tasks:

Synchronize subscriptions.
Specify whether only the upload phase, only the download phase, or both phases are run during synchronization.
Validate that a subscription has the expected data.
Specify a different snapshot folder, from which the initial snapshot for a subscription can be applied.

예

In the following example, the Synchronize method is called on the instance of the MergeSynchronizationAgent class that is accessed from the SynchronizationAgent property to synchronize the push subscription.

         // Define the server, publication, and database names.
            string subscriberName = subscriberInstance;
            string publisherName = publisherInstance;

            string subscriptionDbName = "AdventureWorks2012Replica";
            string publicationDbName = "AdventureWorks2012";

            // Create a connection to the Publisher.
            ServerConnection conn = new ServerConnection(publisherName);

            MergeSubscription subscription;

            try
            {
                // Connect to the Publisher
                conn.Connect();

In the following example, an instance of the MergeSynchronizationAgent class is used to synchronize a merge subscription. Because the pull subscription was created by using a value of false for CreateSyncAgentByDefault, additional properties must be supplied.
