Question

我想用c＃编写一个日志文件。每当有消息发送到远程mq时。示例：假设将abcd消息发送到远程MQ，然后日志文件将记录类似的消息，在10-09-2018 11:30 AM在远程MQ中收到时间和日期。我怎么能做到这一点。可以编写这种代码吗？任何线索，任何想法，任何链接都会有所帮助。请帮忙。

        MQQueueManager queueManager;
        MQMessage queueMessage;
        MQGetMessageOptions queueGetMessageOptions;
        MQQueue queue;


        string QueueName;
        string QueueManagerName;
        string ChannelInfo;
        string channelName;
        string PortNumber;
        string transportType;
        string connectionName;

        QueueManagerName = ConfigurationManager.AppSettings["QueueManager"]; 
        QueueName = ConfigurationManager.AppSettings["Queuename"];
        ChannelInfo = ConfigurationManager.AppSettings["ChannelInformation"];
        PortNumber = ConfigurationManager.AppSettings["Port"];
        char[] separator = { '/' };
        string[] ChannelParams;
        ChannelParams = ChannelInfo.Split(separator);
        channelName = ConfigurationManager.AppSettings["Channel"];
        transportType = ConfigurationManager.AppSettings["TransportType"];
        connectionName = ConfigurationManager.AppSettings["ConnectionName"];
        String strReturn = "";

        try
        {
            queueManager = new MQQueueManager(QueueManagerName,
            channelName, connectionName);
            strReturn = "Connected Successfully";

            queue = queueManager.AccessQueue(QueueName,
            MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_FAIL_IF_QUIESCING);
            queueMessage = new MQMessage();
            queueMessage.Format = MQC.MQFMT_STRING;
            queueGetMessageOptions = new MQGetMessageOptions();
            queue.Get(queueMessage, queueGetMessageOptions);
            strReturn = queueMessage.ReadString(queueMessage.MessageLength);
        }
        catch (MQException exp)
        {
            strReturn = "Exception: " + exp.Message;
        }

        string path1 = @"C:\documents\Example.txt";
        System.IO.File.WriteAllText(path1, strReturn);

这个问题与MQ无关。这只是一个基本的C＃编程问题。您可以使用许多C＃日志记录框架。

这里是2种登录C＃的基本方法。创建自己的“记录器”类并将其放入其中。

public static void WriteLog(String logFileName, byte[] data)
{
   FileStream fs = null;
   DateTime currentDT = DateTime.Now;
   String header = currentDT.ToString("yyyy/MM/dd HH:mm:ss.fff") + " ";
   String LF = "\n";

   try
   {
      fs = new FileStream(logFileName, FileMode.Append, FileAccess.Write, FileShare.ReadWrite);

      if (fs.CanWrite)
      {
         fs.Write(Encoding.Default.GetBytes(header), 0, header.Length);
         fs.Write(data, 0, data.Length);
         fs.Write(Encoding.Default.GetBytes(LF), 0, LF.Length);
      }
   }
   catch (IOException ex)
   {
      Console.WriteLine(ex.Message);
   }
   finally
   {
      try
      {
         if (fs != null)
            fs.Close();
      }
      catch (IOException ex)
      {
         Console.WriteLine(ex.Message);
      }
   }
}

public static void WriteLog(String logFileName, String data)
{
   FileStream fs = null;
   StreamWriter sw = null;
   DateTime currentDT = DateTime.Now;
   String header = currentDT.ToString("yyyy/MM/dd HH:mm:ss.fff") + " ";
   String LF = "\n";

   try
   {
      fs = new FileStream(logFileName, FileMode.Append, FileAccess.Write, FileShare.ReadWrite);

      if (fs.CanWrite)
      {
         sw = new StreamWriter(fs);
         sw.Write(header);
         sw.Write(data);
         sw.Write(LF);
      }
   }
   catch (IOException ex)
   {
      Console.WriteLine(ex.Message);
   }
   finally
   {
      try
      {
         if (sw != null)
            sw.Close();
      }
      catch (IOException ex)
      {
         Console.WriteLine(ex.Message);
      }

      try
      {
         if (fs != null)
            fs.Close();
      }
      catch (IOException ex)
      {
         Console.WriteLine(ex.Message);
      }
   }
}

然后在MQ应用程序中，从队列成功获取消息后，您可以执行以下操作来记录该消息：

Logger.WriteLog("C:\temp\mylog.txt", "message received");
