Using Fluentscheduler to dispatch tasks in Gizhgara Dotnet.webform

Some users have been said that the system sent mail has not been received, the complaint system is not normal, at this time how to wash grievances? Each email sent will be saved to the database, and logs sent to the user, so that users have nothing to say.

Create 3 Tables yourself:

1. Messagefailed-Failed record (more than 5 send failures are saved here)
2. MessageQueue-Information Queue (successfully put Messagesucceed, failed 5 times to save to messagefailed)
3. Messagesucceed-Success Record

With Fluentscheduler, dispatch directly on the web side, eliminating the Windows service program.

Fluentscheduler

Automated job scheduler with fluent interface.

Related code, I used the iregisteredobject to avoid the application pool and the process restart caused by job interruption and other exceptions:

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingsystem.web;namespacedotnet.business{usingDotnet.model; usingdotnet.business; usingdotnet.utilities; usingFluentscheduler; usingSystem.Web.Hosting; #regionMessageregistry Public Partial classMessageregistry:registry { PublicMessageregistry () {//No repeat entry allowedNonreentrantasdefault (); //Schedule an IJob -to-run at an intervalSchedule<messagejob> ().

NewMessagequeuemanager ( This. UserInfo).            Resend (); }        }         Public voidStop (BOOLimmediate) {            //Locking here'll wait for the lock in Execute to be released until this code can continue.            Lock(_lock) {_shuttingdown=true; } hostingenvironment.unregisterobject ( This); }    }    #endregion}

When scheduling, the schedule in Global.asax is as follows:

// Fluentscheduler Task Scheduling FluentScheduler.JobManager.Initialize (new DotNet.Business.MessageRegistry ());

Message-related code, messagefailed messages in the Send Error record is not implemented temporarily:

#regionResend Message/// <summary>        ///Resend Message/// </summary>        /// <param name= "id" >PRIMARY Key</param>        /// <returns>is successful</returns>         Public BOOLResend (messagequeueentity entity,intMaxfailcount =5)        {            BOOLresult =false; if(Entity. Messagetype.tolower (). Contains ("Mail"))            {                if(Mailutil.send (entity. Recipient, entity. Subject, entity.

Because this background job scheduling is sent by mail, in fact, MVC Project can also directly use the above code.
