Question

我正在尝试使用.Net Core 2.2连接到WebsphereMQ队列。我真的很困惑如何做到这一点。在显示我正在尝试（和失败）的内容之前，我需要澄清一下：

我应该使用哪个库以及如何获取它？（NMS？AMQP？WebsphereClient？）
- 我已经看到一些示例，这些示例通常使用安装WebsphereMQ（???）时附带的某些DLL。那是对的吗？我需要安装WebsphereMQ吗？（现在，我将其保存在可以连接到所需队列的远程服务器中。）

到目前为止，我一直尝试安装WebSphereMQClient并尝试使用以下代码连接到队列：

    public void StartListener()
    {
        try
        {
            var xff = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ);
            var cf = xff.CreateConnectionFactory();
            cf.SetStringProperty(XMSC.WMQ_HOST_NAME, WebsphereMqHost);
            cf.SetIntProperty(XMSC.WMQ_PORT, WebsphereMqPort);
            cf.SetStringProperty(XMSC.WMQ_CHANNEL, WebsphereMqChannel);
            cf.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, WebsphereMqQueueManager);
            cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT);

            var conn = cf.CreateConnection();
            var sess = conn.CreateSession(false, AcknowledgeMode.AutoAcknowledge);
            var queue = sess.CreateQueue(QueueName);
            var consumer = sess.CreateConsumer(queue);

            consumer.MessageListener = OnWebsphereMsg;

            conn.Start();
        }
        catch (Exception e)
        {
            _logger.LogError(e);
        }
    }

但是我在第一行遇到了一个例外：

System.Exception: Fatal error. Failed to initialize XMSFactoryFactory ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'IBM.XMS.Client.Impl.XmsFactoryFactoryImpl' threw an exception. ---> System.TypeInitializationException: The type initializer for 'IBM.XMS.Util.Tr' threw an exception. ---> System.TypeInitializationException: The type initializer for 'IBM.XMS.Util.ConfigMgr' threw an exception. ---> System.MissingMethodException: Method not found: 'System.AppDomainSetup System.AppDomain.get_SetupInformation()'.

   at MyApp.Integrations.Configurations.WebsphereMqIntegrationsManager.StartListener(ListenersEnum listener, Dictionary`2 parameters).

我注意到WebsphereMqClient与.NET Standard不兼容。是由于该错误引起的吗？如何使用.NET Core应用程序连接到Websphere？

谢谢

amqmxmsstd.dll是必须使用的库，可以从MQ v9.1.1中获得。以下是信息中心链接，该链接讨论将XMS与Microsoft .NET Core一起使用。 Using XMS with Microsoft .NET Core

您将需要amqmdnetstd.dll和amqmxmsstd.dll来开发XMS .NET应用程序，并且这两个dll都是使用.NET Standard构建的。以下信息中心链接介绍了用于构建这些库的框架。 Installing IBM MQ classes for .NET Standard

正如Josh所指出的，您可以使用MQ Redist客户端来获取库。从IBM MQ Redist clients下载“ 9.1.1.0-IBM-MQC-Redist-Win64”

带有.Net Core 2.2的WebsphereMQ
