Beispiele

Im folgenden Beispiel wird die Methode Synchronize auf die Instanz der Klasse TransSynchronizationAgent aufgerufen, die von der SynchronizationAgent Eigenschaft zur Synchronisation des Push-Subscriptions abgerufen wird.

// Define the server, publication, and database names.
string subscriberName = subscriberInstance;
string publisherName = publisherInstance;
string publicationName = "AdvWorksProductTran";
string subscriptionDbName = "AdventureWorks2012Replica";
string publicationDbName = "AdventureWorks2012";

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

TransSubscription subscription;

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

    // Define the push subscription.
    subscription = new TransSubscription();
    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 Distribution Agent for the subscription.
            subscription.SynchronizationAgent.Synchronize();

Hinweise

Die Klasse TransSynchronizationAgent unterstützt die Möglichkeit, Abonnements programmatisch auf transaktionale oder Snapshot-Veröffentlichungen zu synchronisieren.

Threadsicherheit

Die Klasse TransSynchronizationAgent unterstützt keine Multithreaded Apartments. Man kann ein Single-Threaded Apartment angeben, indem man das [STAThread] Attribut auf der Methode deklariert, das der Haupteinstiegspunkt für die Anwendung ist. Dies ist der Standard für Microsoft Windows-basierte Anwendungen, die mit Microsoft Visual Studio erstellt werden.
