c# - 如何在获取 Topic.Name 时避免 2019 MQRC_HOBJ_ERROR

Question

以下是使用时

int topicOptions = MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING;
MQTopic mqTopic = qmgr.AccessTopic(mqCloneSpecs.topicString, "", 
    MQC.MQTOPIC_OPEN_AS_PUBLICATION, topicOptions);

程序的上述部分构建了一个 QueueManager 列表和一个 Topics 列表，用于调用 Windows 服务中的侦听器类。

int tLoopCounter = 0;
foreach (MQTopic topic in topicOut)
{
    tLoopCounter++;
    // NOTE: We blow up here with 2019 MQRC_HOBJ_ERROR if we access the property topic.Name 
    //Console.WriteLine("Loop through topics topic.IsOpen: " + topic.IsOpen); 
    //Console.WriteLine(" OpenOptions:" + topic.OpenOptions); 
    debugLocation = "4053";
    Console.WriteLine(" OpenStatus=" + topic.OpenStatus);


    debugLocation = "4054";
    i = tLoopCounter - 1;
    Console.WriteLine("i=" + i);
    debugQueueInfo = " topicPut #" + tLoopCounter + " QueueMgr:" + queueManagerForTopicsOut[i].Name.TrimEnd();

    // currently getting 2019 : MQRC_HOBJ_ERROR on the line below 
    debugLocation = "4055";
    debugQueueInfo += "Topic:" + topic.Name; 
    Console.WriteLine("Pump:Topic.Put:" + debugLocation + ":" + debugQueueInfo);

    debugLocation = "4057";
    topic.Put(mqMessage);
    Console.WriteLine("Pump:Topic.Put completed"); 

}

当我尝试添加查询选项时，如下所示：

int topicOptions = MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING + MQC.MQOO_INQUIRE;

然后我死于此错误：

DebugLocation=Q3012 异常：System.ApplicationException：访问队列中的 MQException ---> IBM.WMQ.MQException：MQRC_OPTIONS_ERROR

此外，来自 Console.WriteLIne 的 OpenStatus=True，位于 debugLocation=4053。我的第一个想法是，如果它被关闭，那会导致这个错误。
