Moving poison messages to processing queue

Question

I'm trying to add functionality to a system support website that will move messages from the poison queue back to the processing queue. This is what I've attempted so far:

// path = "FormatName:DIRECT=OS:machine-name\private$\queue-name";

var poisonQueue = new MessageQueue(path + ";poison");
var processingQueue = new MessageQueue(path);

foreach(var message in poisonQueue.GetAllMessages())
{
    processingQueue.Send(message);
}

var poisonCount = poisonQueue.GetAllMessages().Count();
var processingCount = processingQueue.GetAllMessage().Count();

Unfortunately, Send() doesn't seem to be doing anything. The debugger shows the counts as:

poisonCount: 6
processingCount: 0

Answer 1

You should move poison messages to retry queue and then messages will be processed again
