如何：重新初始畫訂閱 (以程式設計方式)

  • 發行項

在此主題中，您將學習如何使用 SqlCeReplication 類別，在 Microsoft SQL Server Compact 3.5 上重新初始化訂閱。如需有關使用 SqlServerCe 命名空間的詳細資訊，請參閱 SqlServerCe 命名空間參考文件集。

若要重新初始化訂閱

  1. 初始化 SqlCeReplication 物件。

    SqlCeReplication repl = new SqlCeReplication();

  2. 設定連接屬性。這些屬性指定您要訂閱的發行集名稱及位置、本機 SQL Server Compact 3.5 資料庫的名稱及位置，以及 SQL Server Compact 3.5 伺服器代理程式的位置。

    repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa35.dll";
repl.InternetLogin = "MyInternetLogin";
repl.InternetPassword = "<password>";
repl.Publisher = "MyPublisher";
repl.PublisherDatabase = "MyPublisherDatabase";
repl.PublisherLogin = "MyPublisherLogin";
repl.PublisherPassword = "<password>";
repl.Publication = "MyPublication";
repl.Subscriber = "MySubscriber";
repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

  3. 呼叫 ReinitializeSubscription 方法來標記重新初始化的訂閱。如果傳遞 true 給 ReinitializeSubscription 方法，訂閱者的變更會在重新初始化開始前上傳到發行者。若是傳遞 false，會在重新初始化期間捨棄訂閱者上的任何變更。

    repl.ReinitializeSubscription(true);

  4. 若要重新擴展訂閱，必須在呼叫 ReinitializeSubscription 方法後呼叫 Synchronize 方法。

    repl.Synchronize();

範例

此範例顯示如何重新初始化 SQL Server Compact 3.5 訂閱。在此範例中，訂閱者的任何變更會先上傳到發行者，接著重新初始化訂閱，然後進行資料同步處理。

SqlCeReplication repl = null;

try
{
   // Create SqlCeReplication instance
   //
   repl = new SqlCeReplication();
   repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa35.dll";
   repl.InternetLogin = "MyInternetLogin";
   repl.InternetPassword = "<password>";
   repl.Publisher = "MyPublisher";
   repl.PublisherDatabase = "MyPublisherDatabase";
   repl.PublisherLogin = "MyPublisherLogin";
   repl.PublisherPassword = "<password>";
   repl.Publication = "MyPublication";
   repl.Subscriber = "MySubscriber";
   repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

   // Mark the subscription for reinitialization with Upload first
  
   repl.ReinitializeSubscription(true);

   // Synchronize to SQL Server to populate the Subscription 

   repl.Synchronize();
}
catch (SqlCeException)
{
   // Handle errors here
}
finally
{
   // Dispose the repl object
   
   repl.Dispose();
}

Dim repl As SqlCeReplication = Nothing

Try
   ' Create SqlCeReplication instance

   repl = New SqlCeReplication()
   repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa35.dll"
   repl.InternetLogin = "MyInternetLogin"
   repl.InternetPassword = "<password>"
   repl.Publisher = "MyPublisher"
   repl.PublisherDatabase = "MyPublisherDatabase"
   repl.PublisherLogin = "MyPublisherLogin"
   repl.PublisherPassword = "<password>"
   repl.Publication = "MyPublication"
   repl.Subscriber = "MySubscriber"
   repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf"

   ' Mark the subscription for reinitialization with Upload first
            
   repl.ReinitializeSubscription(True)

   ' Synchronize to SQL Server to populate the Subscription 

   repl.Synchronize()
Catch
   ' Handle errors here
Finally
   ' Dispose the repl object
   
   repl.Dispose()
End Try
