如何调度数据库任务 ASP.NET Core？

Question

I've built a simple student management system. In my application, I need a scheduler for 1st day of every month student due amount will increase by the given number and update student info in the database.

I tried with hangfire and it worked well on the local machine, but it did not work when I deployed the application to the web server.

Now how can I do these kinds of mechanisms?

Thank you.

You can use the IHostedService interface and register using:

services.AddHostedService<MyScheduler>();

MyScheduler

public class MyScheduler : IHostedService
{
    public async Task StartAsync(CancellationToken cancellationToken)
    {
        // Start a timer that will run every x minutes to see
        // if the conditions are met to perform your action
    }

    public async Task StopAsync(CancellationToken cancellationToken)
    {
        // Dispose of Timer
    }
}
