How do I call a function automatically in the API?

Hello everyone

I wrote an API using Asp.Net Core .I want a function to run automatically every 10 minutes. How can I do such a thing?

I need your help . Thanks in advance.

public void AutoUpdate()
{
   var startTimeSpan = TimeSpan.Zero;
   var periodTimeSpan = TimeSpan.FromMinutes(10);
   var dbData = _provinceDataDal.GetAll();

   var timer = new System.Threading.Timer((e) =>
   {
     UpdateData(dbData);
   }, null, startTimeSpan, periodTimeSpan);
}

I used a method like use but it didn't work as I wanted. Because it works only once.

I want it to run my updateData function above for 10 minutes without having to trigger it when the API first runs and again.

Since asp.net core 2.1 are the background tasks with hosted services.

First, configure the services in Startup

public IServiceProvider ConfigureServices(IServiceCollection services)
{
   //Other DI registrations;

   // Register Hosted Services
   services.AddHostedService<MyServices>();
}

After, you implement the ExecuteAsync method with the code of what you want to do

    public class MyServices : BackgroundService
    {
        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            _logger.LogDebug("Starting");

            stoppingToken.Register(() =>
                _logger.LogDebug("Stopping."));

            while (!stoppingToken.IsCancellationRequested)
            {
                _logger.LogDebug($"Working");

                // Your code here

                await Task.Delay(TimeSpan.FromMinutes(1), stoppingToken);
            }

            _logger.LogDebug($"Stopping.");
        }
   }

You are looking for IHostedService. Example with timer you can find here - Timed background tasks. Keep in mind that it is good to use a BackgroundService base class during implementation.
