備註
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.
The MergeSynchronizationAgent class can be used with Publishers and Subscribers that are running on both SQL Server 2000 and SQL Server 2005.
A MergeSynchronizationAgent class cannot be used with Distributors that are running on SQL Server 2000.
範例
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 publicationName = "AdvWorksSalesOrdersMerge";
string subscriptionDbName = "AdventureWorks2008R2Replica";
string publicationDbName = "AdventureWorks2008R2";
// Create a connection to the Publisher.
ServerConnection conn = new ServerConnection(publisherName);
MergeSubscription subscription;
try
{
// Connect to the Publisher
conn.Connect();
// Define the subscription.
subscription = new MergeSubscription();
subscription.ConnectionContext = conn;
subscription.DatabaseName = publicationDbName;
subscription.PublicationName = publicationName;
subscription.SubscriptionDBName = subscriptionDbName;
subscription.SubscriberName = subscriberName;
// If the push subscription exists, start the synchronization.
if (subscription.LoadProperties())
{
// Check that we have enough metadata to start the agent.
if (subscription.SubscriberSecurity != null)
{
// Synchronously start the Merge Agent for the subscription.
subscription.SynchronizationAgent.Synchronize();
}
else
{
throw new ApplicationException("There is insufficent metadata to " +
"synchronize the subscription. Recreate the subscription with " +

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.
