MSMQ 忽略事务范围

Question

我正在尝试从 MSMQ 私有队列中读取数据，并且正在尝试测试失败，以便我可以确信如果进程没有完成，那么详细信息将保留在队列中。目前在我的事务范围内，它命中了我的 throw new Exception 行并按预期落入 catch 块，但看起来 transaction.Complete 得到了运行，因为在抛出异常之后，队列为空：这是我的代码片段 -

try
        {

            using (TransactionScope transaction = new TransactionScope())
            {

                Message incoming = new Message
                {
                    Formatter = formatter,
                    AcknowledgeType = AcknowledgeTypes.FullReceive,
                    Recoverable = true

                };

                incoming = msgQ.Receive(new TimeSpan(0, 0, 3), MessageQueueTransactionType.Single);

                if (incoming != null)
                {
                    MemoryStream mem = (MemoryStream) incoming.BodyStream;
                    mem.Seek(0, SeekOrigin.Begin);
                    IFormatter ifm = new BinaryFormatter();
                    var deserialisedMessage = (TravelMessageServiceObjects) ifm.Deserialize(mem); 
                    ISubmissionsService submissionsService = new SubmissionsService();
                    bool retVal = submissionsService.PerformSubmission(deserialisedMessage.Products, deserialisedMessage.PolicyReference);
                    if (!retVal)
                    {

                        string errorMessage = string.Concat("Policy Ref: ", deserialisedMessage.PolicyReference,
                            " Product: ", Enum.GetName(typeof(Products), deserialisedMessage.Products));
                        throw new Exception(errorMessage);
                    }
                }
                transaction.Complete();
            }

        }
        catch (Exception ex)
        {
            IError logger = new Logger();
            logger.Log(this, SeverityEnum.Warning, ex);

        }

将您的队列创建为事务性队列

并将MessageQueueTransactionType设置为Automatic。 Single 仅适用于内部消息队列事务。

incoming = msgQ.Receive(new TimeSpan(0, 0, 3), MessageQueueTransactionType.Automatic);

检查，MSDTC 正常。

检查，防火墙没有阻止通信
