Пример
Следующий пример кода синхронизует три одноранговых узла и обрабатывает исключение типа 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");
