Hi,
I have searched in the internet and I have written a sample code in c# for sending an ascii file through MQ. But all I have found are about sending a string and not a file. I have written the following code, using streamfile and fill a string variable named "text". Then I use this variable to send it through MQ queue :
public void GetFile()
{
String path = "C:\\file.txt";
StreamReader streamReader = new StreamReader(path);
text = streamReader.ReadToEnd();
streamReader.Close();
}
public void PutMessageOnQueue(string message)
{
try
{
message = text;
queue = queueManager.AccessQueue(queueName, MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING);
queueMessage = new MQMessage();
queueMessage.WriteString(message);
queueMessage.Format = MQC.MQFMT_STRING;
queue.Put(queueMessage);
}
catch (MQException mqexp)
{
Console.WriteLine("MQSeries Exception: " + mqexp.Message);
Console.WriteLine("MQSeries Exception: " + mqexp.Reason);
Console.WriteLine("MQSeries Exception: " + mqexp.StackTrace);
}
}
Can you please help me with the code?
Regards,
John |

| A file is just a string of bytes. |

Your code design is correct. Read the entire file into a string (or some other suitable buffer type, eg. byte array). Put the string as an MQ message.

Hello,
Message is written in the queue, but although the ascii file has 5 lines, MQ queue writes the data in one single line. I was expected to have a message with 5 lines separated by carriage return character.
I have changed C# code using an array:
mqMsg = new MQMessage();
string[] lines = System.IO.File.ReadAllLines(@"C:\\Users\\vdt003.txt");
foreach (string line in lines)
{
message = line ;
msgLen = message.Length;
if (msgLen > 0)
.................
}
Can you please help?
Thanks John |

If you imbed CR/LF characters in the data you put to the queue, they will be there when you get the message out of the queue. Messages are not files, and therefore to not adhere to file protocols like CR/LF.

An MQ message is just a string of bytes.
A string of bytes doesn't know that 0x0a0x0d is a "line ending". |

You need to read the entire file into a single string as one entity, not as a sequence of records (appended together without line terminators).
