No exemplo a seguir, o Synchronize método é chamado na instância da MergeSynchronizationAgent classe que é acessada da SynchronizationAgent propriedade para sincronizar a assinatura push.

No exemplo a seguir, uma instância da MergeSynchronizationAgent classe é usada para sincronizar uma assinatura de mesclagem. Como a assinatura pull foi criada usando um valor para falseCreateSyncAgentByDefault, propriedades adicionais devem ser fornecidas.

Comentários

A MergeSynchronizationAgent classe dá suporte à capacidade de realizar as seguintes tarefas de replicação:

• Sincronizar assinaturas.

• Especifique se somente a fase de carregamento, apenas a fase de download ou ambas as fases são executadas durante a sincronização.

• Valide se uma assinatura tem os dados esperados.

• Especifique uma pasta de instantâneo diferente, da qual o instantâneo inicial de uma assinatura pode ser aplicado.
