Read And Write To Header Message MQ C#

Question

I am reading an MQMessage in like so

       queue.Get(message, gmo);

        string message1 = message.ReadString(message.MessageLength);

I can see there is a message.UserId on MQMessage , but that is not enough

I want the users to get additional information in the message header of an MQMessage.

How can I set and then retrieve the following from a header of an MQMessage

username 
password
mySpecialID

Answer 1

可以这样做

msg.SetStringProperty("NicksProp", "blahblah");

Answer 2

Note: MQ treats message properties as plain text, so if you are sending a password as a message property then EVERYONE can see it. You will be able to see it via WireShark, and/or in the queue with any tool (MQ Explorer) and/or in the MQ log files.
