Ejemplo

En el ejemplo siguiente se muestra cómo guardar un conflicto de restricción temporal utilizando un objeto MemoryConflictLog.

Public Sub SaveConstraintConflict(ByVal conflictingChange As ItemChange, ByVal conflictingItemId As SyncId, ByVal reason As ConstraintConflictReason, ByVal conflictingChangeData As Object, ByVal conflictingChangeKnowledge As SyncKnowledge, ByVal temporary As Boolean) Implements INotifyingChangeApplierTarget2.SaveConstraintConflict
    If Not temporary Then
        ' The in-memory conflict log is used, so if a non-temporary conflict is saved, it's
        ' an error.
        Throw New NotImplementedException("SaveConstraintConflict can only save temporary conflicts.")
    Else
        ' For temporary conflicts, just pass on the data and let the conflict log handle it.
        _memConflictLog.SaveConstraintConflict(conflictingChange, conflictingItemId, reason, conflictingChangeData, conflictingChangeKnowledge, temporary)
    End If
End Sub

public void SaveConstraintConflict(ItemChange conflictingChange, SyncId conflictingItemId, 
    ConstraintConflictReason reason, object conflictingChangeData, SyncKnowledge conflictingChangeKnowledge, 
    bool temporary)
{
    if (!temporary)
    {
        // The in-memory conflict log is used, so if a non-temporary conflict is saved, it's
        // an error.
        throw new NotImplementedException("SaveConstraintConflict can only save temporary conflicts.");
    }
    else
    {
        // For temporary conflicts, just pass on the data and let the conflict log handle it.
        _memConflictLog.SaveConstraintConflict(conflictingChange, conflictingItemId, reason, 
            conflictingChangeData, conflictingChangeKnowledge, temporary);
    }
}
