Esempio

Nell'esempio di codice seguente viene illustrato come sincronizzare tre peer e come gestire le eccezioni di tipo DbOutdatedSyncException.

//The SampleStats class handles information from the SyncStatistics
//object that the Synchronize method returns.
SampleStats sampleStats = new SampleStats();

try
{
    //Initial synchronization. Instantiate the SyncOrchestrator
    //and call Synchronize. Note that data is not synchronized during the
    //session between peer 1 and peer 3, because all rows have already
    //been delivered to peer 3 during its synchronization session with peer 2.
    SyncOrchestrator sampleSyncAgent;
    SyncOperationStatistics syncStatistics;

    sampleSyncAgent = new SampleSyncAgent(Utility.ConnStr_DbSync1, Utility.ConnStr_DbSync2);
    syncStatistics = sampleSyncAgent.Synchronize();
    sampleStats.DisplayStats(syncStatistics, "initial");

    sampleSyncAgent = new SampleSyncAgent(Utility.ConnStr_DbSync2, Utility.ConnStr_DbSync3);
    syncStatistics = sampleSyncAgent.Synchronize();
    sampleStats.DisplayStats(syncStatistics, "initial");

    sampleSyncAgent = new SampleSyncAgent(Utility.ConnStr_DbSync1, Utility.ConnStr_DbSync3);
    syncStatistics = sampleSyncAgent.Synchronize();
    sampleStats.DisplayStats(syncStatistics, "initial");
}


catch (DbOutdatedSyncException ex)
{
    Console.WriteLine("Outdated Knowledge: " + ex.OutdatedPeerSyncKnowledge.ToString() +
                      " Clean up knowledge: " + ex.MissingCleanupKnowledge.ToString());
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}
'The SampleStats class handles information from the SyncStatistics

Dim sampleStats As New SampleStats()

    'Initial synchronization. Instantiate the SyncOrchestrator
    'and call Synchronize. Note that data is not synchronized during the

    Dim sampleSyncAgent As SyncOrchestrator
    Dim syncStatistics As SyncOperationStatistics

    sampleSyncAgent = New SampleSyncAgent(Utility.ConnStr_DbSync1, Utility.ConnStr_DbSync2)
    syncStatistics = sampleSyncAgent.Synchronize()

    Console.WriteLine(ex.Message)
End Try
