How can I read a IBM WebSphere MQ message of format type MQEVENT in c#

Question

I can get the event messages from the queue. I get the message properties. I am pretty sure the MQEVENT type is in PCF format but I cannot seem to find any good documentation on how to take that message and convet it into human readable format.

And here is the message.

if (myMQMessage.Format.CompareTo(MQC.MQFMT_EVENT) == 0) I think it needs to be processed twice. First process the PCF header with MQCFH

BuildMQCFH(new IBM.WMQ.PCF.MQCFH(myMQMessage));

public void BuildMQCFH(IBM.WMQ.PCF.MQCFH eventMessageHeader) {
  int reasonForEvent = eventMessageHeader.Reason;
}

Then you MUST reset the DataOffset to 0

myMQMessage.DataOffset = 0;

Second process the PCF parameters with PCFParameter. BuildPcfMessage(new IBM.WMQ.PCF.PCFMessage(myMQMessage));

public void BuildPcfMessage(IBM.WMQ.PCF.PCFMessage pcfMessage) {
  IBM.WMQ.PCF.PCFParameter[] pcfParameters = pcfMessage.GetParameters();
  afflictedQueueManager = pcfParameters[0].GetValue().ToString();
  afflictedQueue = pcfParameters[1].GetValue().ToString();
}

MQMessage, PCF.PCFMessage and MQCF each do a readbyte(s) moving the offset with out resetting afterwards.
