Question

我有一个似乎没有回滚并发生奇怪错误的转换。我正在使用在不同服务器上连接到SQL Server 2008的事务，并在与代码相同的服务器上使用MSMQ。以下是代码示例：

void MyMethod()
    {
       try
       {
           using (var outterTrans = new TransactionScope())
           {
               try
               {
                  InsertA();
                  SendTransactionMsmqMsg(new BlahObject());
               }
               catch (Exception e)
               {
                   //Exception is getting written here.
                   using (new TransactionScope(TransactionScopeOption.Suppress))                      
                      HandleException(e);

                    throw;
                }

                InsertB();
                outterTrans.Complete();
           }
        }
        catch(Exception e)
        {
            //Exception is getting written here too.
            HandleException(e);
        }
    }

    public void InsertA()
    {
       //Inserts data.
    }


    public void InsertB()
    {
       //Inserts data.
    }

    void SendTransactionMsmqMsg(object obj)
    {
         //When calling Msmq.Send I get 'The PROMOTE TRANSACTION request failed because there is no local transaction active.'
         Msmq.Send(CreateMessage(obj), MessageQueueTransactionType.Automatic);
    }

当发生这种情况时，SendTransactionMsmqMsg之前的所有内容都不会回滚。这种情况也很罕见。这也是一些堆栈跟踪：

我不确定我做错了什么以及导致这个问题的原因。我似乎无法生成同样的异常，并且我生成的每个异常都会回滚。任何人都知道我怎么能够产生这个错误？

感谢大家的帮助！

DTC是否在所有涉及工作的服务器上运行？所有进程都有适当的访问权限吗？

此帖子收到的错误消息相同： Membership.GetUser() within TransactionScope throws TransactionPromotionException

<强>更新

实例化消息队列对象在哪里？我会尝试在事务范围内实例化它。

交易没有回滚
