Hi everyone!

My code:
Code:

public List<string> GetALLQueue(string qmName, bool isFindSystemQueue = false)

    {

        PCFMessageAgent agent = new PCFMessageAgent(qmName);

        PCFMessage request = new PCFMessage(CMQCFC.MQCMD_INQUIRE_Q_NAMES);

        request.AddParameter(MQC.MQCA_Q_NAME, "*");

        PCFMessage[] response = agent.Send(request);

        string[] names = response[0].GetStringListParameterValue(CMQCFC.MQCACF_Q_NAMES);

        List<string> result = null;

        if (!isFindSystemQueue)

            result = names.ToList().Where(s => !s.Contains("AMQ.") && !s.Contains("SYSTEM.")).ToList();

        else

            result = names.ToList();

        return result;

    }


The error is "Index and count must refer to a location within the buffer." in code
Code:
PCFMessage[] response = agent.Send(request);
.

MQ version is Websphere MQ 7.5.0.5.
Language is c# and Framework 4.5.

Any ideas what i am doing wrong?

Did you check the reason code on response?
Did you check if response was null?
What else could need checking that you are bypassing happily?

Thank you for your prompt reply.
I already checked reason code.
No response was received from AMQERR01.LOG
I am a new user.
I´m clueless what I should check.
Could you tell me? Thank you!

Your code does not say so. You retrieve an array of PCF messages, but you do not check if the array is empty... and then you merrily and happily look at the first message in the array....

Should that message exist (probably not given the error you are receiving) you go to check its content without examining the reason code / return code it holds... first...

Have fun
