Edit MSMQ messages in a queue

I need to be able to edit messages in my error queue (so that they can be resent to the actual queue for reprocessing).

I would like to make my own custom tool to do this (because my messages require specific formatting to make them easily readable by support personnel).

I know that this is possible because the application "QueueExplorer" does this.

Does anyone know how I can load an MSMQ message (that is not the first one in the queue), edit it, and save it back to the queue?

MSMQ messages are supposed to be immutable. The best you can do is read the message and send an edited copy of the message back to the queue.

Iterate through the messages, using something like this:

List<Message> msgList = new List<Message>();

using (MessageEnumerator me = queue.GetMessageEnumerator2())
{
  while (me.MoveNext(new TimeSpan(0, 0, 0)))
  {
     Message message = me.Current;
     msgList.Add(message)
  }
}

You can then iterate through the list, processing each message. Create a new message, based on the original. Then remove the existing message, and add the new one.

foreach (Message message in msgList)
{
  //Create a new message as required, add it, then remove the old message
  MessageQueue.ReceiveById(message.MessageId);
}
