. How NET message queues are used

This article is mainly introduced. NET Message queue usage, the need for friends can refer to the following

.   NET uses Message Queuing to store a series of tasks to complete without using the same queue for programs to facilitate data sharing and collaboration among different programs ... In my experience, this is similar in some way to the session (there are many different aspects, of course), the same: session can store information in the Aspnet_state service, the site recompile or restart the site,   Session is not lost (the session timeout is normal, except in this case). Win7 to install Message Queuing components, other operating systems please Baidu search for relevant information. If the service does not start automatically, you need to start the service:   Create queues, then use queues, messages in queues, send one more, receive one less, and advance out first. The   code is as follows: using System; Using System.Collections.Generic; Using System.Linq; Using System.Web; Using System.Web.UI; Using System.Web.UI.WebControls; Using System.Messaging; Add a reference to the physical file System.Messaging namespace TestWeb {    public partial class MSMQtest:System.Web.UI.Page     {        protected void Page_Load (object sender, EventArgs e)         {&N Bsp          //createnewqueue ("Msgqueue");//Create a message queue            //sen Dsimplemsg ()///Every queue is best to send and receive information in the same format, otherwise it is difficult to convert the format.            //receivesimplemsg ();//           //receivesimpl Emsg ();            //sendcomplexmsg ();            //receivecomplexmsg ();             Msgmodel m = receivecomplexmsg<msgmodel> ();             Response.Write (m.tostring ());           {        private void sendsimplemsg ()         {           //materialized MessageQueue, and point to an existing one called Videoqueue queue           & nbsp MessageQueue MQ = new MessageQueue (@ ".
