Beispiel

Im folgenden Codebeispiel werden drei Peers synchronisiert und Ausnahmen des Typs DbOutdatedSyncException verarbeitet.

//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);
