注释

Business logic handlers are registered by calling RegisterBusinessLogicHandler. The properties of the BusinessLogicHandler object must be set before calling RegisterBusinessLogicHandler.

Business logic handler registrations are removed by calling UnregisterBusinessLogicHandler.

Call EnumBusinessLogicHandlers to get a list of business logic handlers that are registered on a server.

示例

           // Specify the Distributor name and business logic properties.
            string distributorName = publisherInstance;
            string assemblyName = @"C:\Program Files\Microsoft SQL Server\100\COM\CustomLogic.dll";
            string className = "Microsoft.Samples.SqlServer.BusinessLogicHandler.OrderEntryBusinessLogicHandler";
            string friendlyName = "OrderEntryLogic";

            ReplicationServer distributor;
            BusinessLogicHandler customLogic;

                // Create a connection to the Distributor.
            ServerConnection distributorConn = new ServerConnection(distributorName);

            try
            {
                // Connect to the Distributor.
                distributorConn.Connect();

                // Set the Distributor properties.
                distributor = new ReplicationServer(distributorConn);

                // Set the business logic handler properties.
                customLogic = new BusinessLogicHandler();
