我们正在尝试在IBM MQ Message Queue上发送消息。
我们可以联系队列管理器，但只要我们调用MQMessage构造函数，该过程就会挂起。我们怀疑这实际上是因为AccessQueue正在做的事情都失败了。
using (MQQueueManager qMgr = new MQQueueManager(queueManagerName, connectionProperties))
{
// Set up the options on the queue we want to open
int openOptions = MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING;
// Now specify the queue that we want to open,and the open options
MQQueue system_default_local_queue =
qMgr.AccessQueue(sendQueueName, openOptions); // we suspect this is actually where things are wrong
// Define a WebSphere MQ message, writing some text in UTF format
MQMessage mqMessage = new MQMessage(); // ** THIS HANGS
mqMessage.WriteUTF(text);
// Specify the message options
MQPutMessageOptions pmo = new MQPutMessageOptions(); // accept the defaults,
// same as MQPMO_DEFAULT
// Put the message on the queue
system_default_local_queue.Put(mqMessage, pmo);
system_default_local_queue.Close();
// Disconnect from the queue manager
qMgr.Disconnect();
}
我们没有包含或我们缺少的选项吗？
我们正在使用NuGet包WebSphereMqClient v8.0.0.7。
更新
我会根据反馈将完整性包含在连接属性中。
Hashtable connectionProperties = new Hashtable();
connectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
connectionProperties.Add(MQC.USE_MQCSP_AUTHENTICATION_PROPERTY, true);
// Set up the rest of the connection properties, based on the
// connection type requested
// this is all for MQC.TRANSPORT_MQSERIES_MANAGED
connectionProperties.Add(MQC.HOST_NAME_PROPERTY, "myserver.com");
connectionProperties.Add(MQC.CHANNEL_PROPERTY, "MY.CHANNEL");
connectionProperties.Add(MQC.PORT_PROPERTY, 3223);
connectionProperties.Add(MQC.CONNECT_OPTIONS_PROPERTY, MQC.MQCNO_RECONNECT_Q_MGR);
在回答Roger提出的问题时，这是一个托管队列。
答案 0 :(得分：2)
您没有向我们展示您的连接属性，因此我不知道您是否正确设置了所有内容。您确定设置了“托管模式”吗？另外，为什么你没有打印出代码完成的内容？
这是一个完整且有效的C＃.NET / MQ程序，它使用＆＃39;托管模式＆＃39;连接。
