C＃中的WebSphere MQ偵聽器

Question

我需要在C＃中編寫基於Windows的服務來偵聽在WebSphere MQ中配置的請求隊列。我成功地將請求放入MQ中並獲取相關ID，但作爲響應，我沒有得到實際結果。

我想開發一個系統，只要有新消息到達隊列中，服務就應該拿起消息並處理請求。我可以將該響應與我的關聯ID進行映射。

以下代碼已解決我的問題。

class Program 
{ 
    static void Main(string[] args) 
    { 
     Program app = new Program(); 
     app.Setup(); 
     Console.ReadLine(); 

    } 

    public void Setup() 
    { 
     XMSFactoryFactory xff = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ); 
     IConnectionFactory cf = xff.CreateConnectionFactory(); 
     cf.SetStringProperty(XMSC.WMQ_HOST_NAME, "10.87.188.156(7111)"); 
     cf.SetIntProperty(XMSC.WMQ_PORT, 7111); 
     cf.SetStringProperty(XMSC.WMQ_CHANNEL, "QMEIGS1.CRM.SVRCONN"); 
     cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT); 
     cf.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, "QMEIGS1"); 
     cf.SetIntProperty(XMSC.WMQ_BROKER_VERSION, XMSC.WMQ_BROKER_V1); 

     IConnection conn = cf.CreateConnection(); 
     Console.WriteLine("connection created"); 
     ISession sess = conn.CreateSession(false, AcknowledgeMode.AutoAcknowledge); 
     IDestination dest = sess.CreateQueue("DOX.APYMT.ESB.SSK.RPO.02"); 
     IMessageConsumer consumer = sess.CreateConsumer(dest); 
     MessageListener ml = new MessageListener(OnMessage); 
     consumer.MessageListener = ml; 
     conn.Start(); 
     Console.WriteLine("Consumer started"); 


    } 

    private void OnMessage(IMessage msg) 
    { 
     ITextMessage textMsg = (ITextMessage)msg; 
     Console.Write("Got a message: "); 
     Console.WriteLine(textMsg.Text); 
    } 

}

我在Z/OS大型機上連接MQ。來自Rashmi的代碼示例爲我做了訣竅，但我需要更改「OnMessage」方法以提取消息：

private void OnMessage(IMessage msg) 
    { 
     IBytesMessage bytesMessage = (IBytesMessage)msg; 

     var buffer = new byte[bytesMessage.BodyLength]; 
     bytesMessage.ReadBytes(buffer, (int)bytesMessage.BodyLength); 
     var messageAsText = Encoding.Unicode.GetString(buffer); 

     Console.Write("Got a message: "); 
     Console.WriteLine(messageAsText); 
    }
