示例

// Specify the Distributor name and business logic properties.
string distributorName = publisherInstance;
string assemblyName = @"C:\Program Files\Microsoft SQL Server\110\COM\CustomLogic.dll";
string className = "Microsoft.Samples.SqlServer.BusinessLogicHandler.OrderEntryBusinessLogicHandler";
string friendlyName = "OrderEntryLogic";

ReplicationServer distributor;

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

try
{

    distributorConn.Connect();

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

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

    Boolean isRegistered = false;

    // Check if the business logic handler is already registered at the Distributor.

    // Register the custom logic.
    if (!isRegistered)

    }
}
catch (Exception ex)
{
    // Do error handling here.
    throw new ApplicationException(string.Format(
        "The {0} assembly could not be registered.",
        assemblyName), ex);
}
finally
{
    distributorConn.Disconnect();

        If registeredLogic Is customLogic Then
            isRegistered = True
        End If
    Next

    ' Register the custom logic.
    If Not isRegistered Then
        distributor.RegisterBusinessLogicHandler(customLogic)
    End If
Catch ex As Exception
    ' Do error handling here.
    Throw New ApplicationException(String.Format( _
     "The {0} assembly could not be registered.", _
     assemblyName), ex)
Finally
    distributorConn.Disconnect()
End Try

注解

方法 EnumBusinessLogicHandlers 只能由 sysadmin 固定服务器角色的成员和db_owner固定数据库角色的成员调用。

调用 EnumBusinessLogicHandlers 等效于执行 sp_enumcustomresolvers (Transact-SQL) 。
