Question

当尝试以绑定模式连接到MQ时（我在本地设置了服务器），我得到以下异常：

 System.TypeInitializationException: The type initializer for 'IBM.WMQ.Nmqi.BindingsNmqiMQ' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.
   at IBM.WMQ.Nmqi.NativeManager.InitializeNativeApis(String mode)

   at IBM.WMQ.MQQueueManager..ctor(String queueManagerName, Hashtable properties)
   at Project.MQConnector.CreateConnectAndAddQueueManager(QueueManagerConnectionDetails connDetails)

尝试连接到队列管理器时发生错误，如下所示：

构造

Friend queueManagerConnectionProperties As New Hashtable()
queueManagerConnectionProperties.Add(MQC.THREAD_AFFINITY_PROPERTY, True)
If My.Settings.MQConnectAsClient Then
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT)
Else
    queueManagerConnectionProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_BINDINGS)
End If

queueManagerConnectionProperties.Add(MQC.CONNECT_OPTIONS_PROPERTY, MQC.MQCNO_HANDLE_SHARE_BLOCK Or MQC.MQCNO_RECONNECT_Q_MGR) ' have handle-sharing with call blocking

在CreateConnectAndAddQueueManager方法中（其中connDetails只是端口，主机，名称等的存储）：

 Dim specificQMConnProperties As Hashtable = CType(queueManagerConnectionProperties.Clone(), Hashtable)
 specificQMConnProperties.Add(MQC.CHANNEL_PROPERTY, connDetails.Channel)
 specificQMConnProperties.Add(MQC.CONNECTION_NAME_PROPERTY, connectionName)
 Dim qmgr As MQQueueManager = Nothing

 Try
     qmgr = New MQQueueManager(connDetails.Name, specificQMConnProperties)
 Catch ex As MQException
     ' error handling
 End Try

我有以下环境变量：

NMQ_MQ_LIB=mqm.dll

当我使用托管连接（NMQ_MQ_LIB=managed;并且未设置MQC.TRANSPORT_PROPERTY）进行连接时，它可以正常工作。

有什么想法吗？

查看您的最新评论。您在GAC中有一些不需要的条目。你需要做一些清理工作。

1）打开命令提示符。

2）运行amqiregisterdotnet.cmd /u命令取消注册MQ .NET程序集。

3）检查Windows GAC MQ .NET程序集。确保没有MQ .NET条目。如果有，请尝试使用gacutil命令手动取消注册。

4）然后运行命令amqiregisterdotnet.cmd再次注册程序集。

希望这有帮助。
