Sample code to save as MSMQ messages from outgoing queues to files

  • Artikel

The following code will read messages from outoging queues and then create folder structure as \domain or server name or IP\private$ or (public)\queue name to save the messages as .xml files.

The reference is the sample from codeproject: https://www.codeproject.com/Articles/22847/Accessing-Outgoing-Message-Queues-MSMQ private void SaveMessages(string queueFormatName, int numOfMessagesToRead) { MSMQ.MSMQQueueInfo info = new MSMQ.MSMQQueueInfo(); info.FormatName = queueFormatName; MSMQ.MSMQQueue mq = info.Open((int)(MSMQ.MQACCESS.MQ_ADMIN_ACCESS | MSMQ.MQACCESS.MQ_PEEK_ACCESS), (int)MSMQ.MQSHARE.MQ_DENY_NONE); for (int i = 0; i < numOfMessagesToRead; i++) { object wantdest = false; object tr = true; object num = 0; MSMQ.MSMQMessage msg = null; try{ if (i == 0) msg = mq.PeekCurrent(ref wantdest, ref tr, ref num, ref wantdest); //Peek(ref wantdest, ref tr, ref num, ref wantdest); else msg = mq.PeekNext(ref wantdest, ref tr, ref num, ref wantdest); } catch (Exception ee) { //MessageBox.Show(ee.ToString()); } if (msg == null) { WriteLine("Number of Messages to read:" + (numOfMessagesToRead - i).ToString() + " msg is null."); continue; } //ASCIIEncoding encoding = new ASCIIEncoding(); UTF8Encoding utf8encoding = new UTF8Encoding(); string queuePathName = queueFormatName.Substring(queueFormatName.IndexOf(":")+1); string path = Directory.GetCurrentDirectory(); path += "\\SavedMessages\\" + queuePathName; //MessageBox.Show(path); if (!Directory.Exists(path)) { Directory.CreateDirectory(path); } byte[] guid = new byte[16]; byte[] seq = new byte[4]; Array.Copy((byte[])msg.Id, 0, guid, 0, 16); Array.Copy((byte[])msg.Id, 16, seq, 0, 4); int seqNumber = BitConverter.ToInt32(seq, 0); Guid msgId = new Guid(guid); path += "\\" + msgId.ToString() + "_" + seqNumber.ToString() + ".xml"; //MessageBox.Show(path); try { File.WriteAllText(path, utf8encoding.GetString((byte[])msg.Body)); } catch (Exception ee) { File.WriteAllText(path, (string)msg.Body); //MessageBox.Show(ee.ToString()); } } }
