'IBM.WMQ.Nmqi.BindingsNmqiMQ' 的类型初始值设定项抛出异常

Question

尝试以绑定模式连接到 MQ 时（我在本地设置了一个服务器），出现以下异常：

 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出现如下错误：

构造函数：

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

并且在 CreateConnectAndAddQueueManager 方法中（其中 connDetails 只是存储端口、主机、名称等）：

 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；并且不设置 MQC.TRANSPORT_PROPERTY）连接时，它工作正常。

有什么想法吗？

正在查看您的最新评论。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 命令注销 MQ .NET 程序集。

3) 检查 Windows GAC 有哪些 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。

希望这对您有所帮助。
