Question

我已经开发了一个asp.net MVC Web应用程序，现在我想每天在后台发送一封电子邮件。我想将此功能添加到已经创建的外部项目中。在该项目中，我创建了此类，我需要一些帮助来完成这项工作。

public class SendMailJob : IJob
{
public Task SendEmail(IJobExecutionContext context)
{

    MailMessage Msg = new MailMessage();

    Msg.From = new MailAddress("mymail@mail.com", "Me");

    Msg.To.Add(new MailAddress("receivermail@mail.com", "ABC"));

    Msg.Subject = "Inviare Mail con C#";

    Msg.Body = "Mail Sended successfuly";
    Msg.IsBodyHtml = true;

    SmtpClient Smtp = new SmtpClient("smtp.live.com", 25);

    Smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

    Smtp.UseDefaultCredentials = false;
    NetworkCredential Credential = new
    NetworkCredential("mymail@mail.com", "password");
    Smtp.Credentials = Credential;

    Smtp.EnableSsl = true;

    Smtp.Send(Msg);

//CONFIGURE JOB TO EXECUTE DAILY
// define the job and tie it to our SendMailJob class
IJobDetail job = JobBuilder.Create<SendMailJob>()
    .WithIdentity("job1", "group1")
    .Build();

// Trigger the job to run now, and then repeat every 24 hours
ITrigger trigger = TriggerBuilder.Create()
    .WithIdentity("trigger1", "group1")
    .StartNow()
    .WithSimpleSchedule(x => x
        .WithIntervalInHours(24)
        .RepeatForever())
    .Build();
}
}

我不了解Quartz.net的工作原理，我遇到的问题如下：

我不知道如何使此功能正常工作（我是否必须在Web应用程序上调用该作业？像在索引视图中一样，如果我想在进入索引视图时开始该作业，该如何进行？）
我在公共任务SendEmail中出错，它说：“并非所有代码路径都返回一个值”，但是我必须返回什么？
我缺少使quartz.net正常工作的东西吗？

发送邮件的代码运行良好，我尝试过在索引视图中放置一个按钮，并在按下按钮时从控制器调用使用我编写的代码的操作。

您需要采取的步骤：

您需要创建一个工作计划程序，该工作计划程序将为您进行计划

    using System;  
    using System.Collections.Generic;  
    using System.Linq;  
    using System.Web;  
    using Quartz;  
    using Quartz.Impl;  

    namespace ScheduledTask.Models  
    {  
        public class JobScheduler  
        {  
            public static void Start()  
            {  
                IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();  
                scheduler.Start();  

                IJobDetail job = JobBuilder.Create<SendMailJob>().Build();  

                ITrigger trigger = TriggerBuilder.Create()  
                .WithIdentity("trigger1", "group1")  
                .StartNow()  
                .WithSimpleSchedule(x => x  
                .withIntervalInHours(24)  
                .RepeatForever())  
                .Build();  

                scheduler.ScheduleJob(job, trigger);  
            }  
        }  
    }

将发送函数重新创建为类似的内容

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Web;  
using Quartz;  
using System.Net;  
using System.Net.Mail;  


namespace ScheduledTask.Models  
{  
    public class Jobclass:IJob  
    {       
        public void Execute(IJobExecutionContext context)  
        {  
                MailMessage Msg = new MailMessage();

                Msg.From = new MailAddress("mymail@mail.com", "Me");

                Msg.To.Add(new MailAddress("receivermail@mail.com", "ABC"));

                Msg.Subject = "Inviare Mail con C#";

                Msg.Body = "Mail Sended successfuly";
                Msg.IsBodyHtml = true;

                SmtpClient Smtp = new SmtpClient("smtp.live.com", 25);

                Smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

                Smtp.UseDefaultCredentials = false;
                NetworkCredential Credential = new
                NetworkCredential("mymail@mail.com", "password");
                Smtp.Credentials = Credential;

                Smtp.EnableSsl = true;

                Smtp.Send(Msg);
            }  
        }  
    }  

}

在global.asax.cs的应用程序启动事件中

    protected void Application_Start(Object sender, EventArgs e)
    {
        // keep whatever other code is there
        JobScheduler.Start();
    }

使用Quartz.net从asp.net MVC Web应用程序在后台发送每日邮件
