Quartz:不实现接口成员 [英] Quartz: Does not implement interface member

问题描述

我正在使用 Quartz 并使用示例代码并得到错误:

I am using Quartz and using sample code and get the error:

CS0738 'EmailJob' 没有实现接口成员IJob.Execute(IJobExecutionContext).EmailJob.Execute(IJobExecutionContext) 无法实现 IJob.Execute(IJobExecutionContext)，因为它没有 >Task 的匹配返回类型.>

CS0738 'EmailJob' does not implement interface member IJob.Execute(IJobExecutionContext). EmailJob.Execute(IJobExecutionContext) cannot implement IJob.Execute(IJobExecutionContext) because it does not > have the matching return type of Task.

这是我第一次使用 Quartz，因此不胜感激.

This is my first go at Quartz so any help would be kindly appreciated.

public class EmailJob : IJob  // <<<--- Error on this line
{
    public void Execute(IJobExecutionContext context)
    {
        using (var message = new MailMessage("[e-mail]", "[e-mail]"))
        {
            message.Subject = "Test";
            message.Body = "Test at " + DateTime.Now;
            using (SmtpClient client = new SmtpClient
            {
                EnableSsl = true,
                Host = "smtp.gmail.com",
                Port = 587,
                Credentials = new NetworkCredential("[e-mail]", "password")
            })
            {
                client.Send(message);
            }
        }
    }

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

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

            ITrigger trigger = TriggerBuilder.Create()
                .WithDailyTimeIntervalSchedule
                  (s =>
                     s.WithIntervalInHours(24)
                    .OnEveryDay()
                    .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(0, 0))
                  )
                .Build();

            scheduler.ScheduleJob(job, trigger);
        }
    }

我直接从这篇精彩的文章中得到了代码:http://www.mikesdotnetting.com/article/254/scheduled-tasks-in-asp-net-with-quartz-net

推荐答案

我刚刚测试了你的代码，它在我这边编译时没有任何变化.您的问题可能是错误的命名空间导入.您可以尝试使用完整的命名空间，如下所示:

I just tested your code and it compiles without any changes on my side. Your problem is maybe a wrong namespace import. You can try with the full namespace like this:

public class EmailJob : Quartz.IJob
{
    public void Execute(Quartz.IJobExecutionContext context)
    {
        using (var message = new MailMessage("[e-mail]", "[e-mail]"))
        {
            message.Subject = "Test";
            message.Body = "Test at " + DateTime.Now;
            using (SmtpClient client = new SmtpClient
            {
                EnableSsl = true,
                Host = "smtp.gmail.com",
                Port = 587,
                Credentials = new NetworkCredential("[e-mail]", "password")
            })
            {
                client.Send(message);
            }
        }
    }

   // ...
}
