Beispiele
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.

SyncOperationStatistics syncStatistics;
sampleSyncAgent = new SampleSyncAgent(Utility.ConnStr_DbSync1, Utility.ConnStr_DbSync2);
