How To Create A New Msmq Message In Ironpython With Label, Reply Queue And Other Properties

I'm following this example here to use MS Message Queues with IronPython. The example works to create a message text string without any properties. import clr clr.AddReference('Sys

Solution 1:

I don't think that this works with IronPython classes, because serialize and deserialize them does not work like it does for c#/.net classes.

The only thing to get this work, will be to get IronPython classes serialize-able and deserialize-able. I think deserialization will be the hard part. But you may proof me wrong.

Solution 2:

I've started guessing the syntax by examining c# examples and have hacked a solution to the problem. The following code delivers a message with a user defined label and response queue and a body message.

import clr

from System import Array
from System import Byte

clr.AddReference('System.Messaging')
from System.Messaging import MessageQueue
from System.Messaging import Message

ourQueue = '.\\private$\python_in'
ourOutQueue = '.\\private$\python_out'ifnot MessageQueue.Exists(ourQueue):
    queue = MessageQueue.Create(ourQueue)
else:
    queue = MessageQueue(ourQueue)

ifnot MessageQueue.Exists(ourOutQueue):
    out_queue = MessageQueue.Create(ourOutQueue)
else:
    out_queue = MessageQueue(ourOutQueue)

mymessage = Message()
mymessage.Label = 'MyLabel'
mymessage.ResponseQueue = out_queue

mystring = 'hello world'
mybytearray = bytearray(mystring)

# this is very hacky
mymessage.BodyStream.Write(Array[Byte](mybytearray),0,len(mybytearray))

queue.Send(mymessage)
