如何使用Hangfire运行基于DateTime的定期作业？ [重复]

Question

此问题已经在这里有了答案：

Hangfire in ASP.Net Core : simple recurring job does not refresh its dynamic content（2个答案）

关闭14小时前。

我正在ASP.NET Core应用中使用Hangfire。我想做这样的工作：每分钟() => Console.WriteLine($"Triggered At {DateTime.Now.ToString()} !!")。我希望得到这个结果：

Triggered At 5/16/2020 3:05:40 PM
Triggered At 5/16/2020 3:06:40 PM
Triggered At 5/16/2020 3:07:40 PM
Triggered At 5/16/2020 3:08:40 PM

但是我得到的结果如下：

Triggered At 5/16/2020 3:05:40 PM
Triggered At 5/16/2020 3:05:40 PM
Triggered At 5/16/2020 3:05:40 PM
Triggered At 5/16/2020 3:05:40 PM

我已使用此代码：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    ...
    ...
    ...
    app.UseHangfireDashboard();

    RecurringJob.AddOrUpdate("TestJob",
        () => Console.WriteLine($"Triggered At {DateTime.Now.ToString()} !!"), "* * * * *");

    app.UseMvc();
}

我要去哪里错了？

谢谢

Answer 1

我认为您应该将其包装在方法中。

Hangfire serializes arguments

public static void Method() {
   Console.WriteLine($"Triggered At {DateTime.Now.ToString()} !!");
}

 RecurringJob.AddOrUpdate("TestJob",
        () => Method(), "* * * * *");
