爲「IBM.WMQ.Nmqi.BindingsNmqiMQ」的類型初始值引發了異常

Question

當試圖連接到MQ的綁定模式（我有一個服務器架設在本地），我得到以下異常：

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.Nmqi.BindingsNmqiMQ..cctor() 
    --- End of inner exception stack trace --- 
    at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor) 
    at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) 
    at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes, StackCrawlMark& stackMark) 
    at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) 
    at System.Reflection.Assembly.CreateInstance(String typeName, Boolean ignoreCase, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) 
    at IBM.WMQ.Nmqi.NmqiEnvironment.GetInstance(String name) 
    at IBM.WMQ.Nmqi.NmqiEnvironment.GetMQI(Int32 id) 
    at IBM.WMQ.MQQueueManager.Connect(String queueManagerName) 
    at IBM.WMQ.MQQueueManager..ctor(String queueManagerName, Hashtable properties) 
    at Project.MQConnector.CreateConnectAndAddQueueManager(QueueManagerConnectionDetails connDetails) 

構造：嘗試連接到一個隊列管理器，如下所示時，會發生

錯誤

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 

而在CreateConnectAndAddQueueManager方法（其中connDetails僅僅是一個存儲用於p ORT，主機名等）：

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 

我有以下環境變量：

NMQ_MQ_LIB=mqm.dll 

當我連接使用受管理的連接（NMQ_MQ_LIB=managed;並且不要設置MQC.TRANSPORT_PROPERTY），它工作正常。

有什麼想法？

Answer 1

看你的最新評論。您在GAC中有一些不需要的條目。你需要做一些清理。

1）打開命令提示符。

2）運行amqiregisterdotnet.cmd /u命令來取消註冊MQ .NET程序集。

3）檢查Windows GAC什麼MQ .NET程序集。確保沒有MQ .NET條目。如果有的話，嘗試使用gacutil命令手動取消註冊。

4）然後運行命令amqiregisterdotnet.cmd再次註冊組件。

希望這會有所幫助。
