using System; using System.Threading; public class Scheduler { private Timer timer; public void ScheduleServiceCall(int frequencyInMinutes) { TimeSpan delay = TimeSpan.FromMinutes(frequencyInMinutes); TimeSpan interval = TimeSpan.FromMinutes(frequencyInMinutes); timer = new Timer(ExecuteServiceCall, null, delay, interval); } private void ExecuteServiceCall(object state) { // Put your service call code here // The service call will be executed based on the specified frequency } }

Hi sunny for that Create a Background Service: using Microsoft.Extensions.Hosting; using Microsoft.Extensions.Logging; using System; using System.Threading; using System.Threading.Tasks; public class MyBackgroundService : BackgroundService { private readonly ILogger _logger; public MyBackgroundService(ILogger logger) { _logger = logger; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { // Get the user's stored frequency from the database or context var frequencyInMinutes = GetUserFrequency(); // Replace with your logic to retrieve the frequency // Wait for the specified interval await Task.Delay(TimeSpan.FromMinutes(frequencyInMinutes), stoppingToken); // Perform the desired logic here, such as calling the service await CallService(); // Log the execution _logger.LogInformation("Service called successfully."); } } private Task CallService() { // Replace with your logic to call the desired service // You can use HttpClient or any other method to make the API call throw new NotImplementedException(); } private int GetUserFrequency() { // Replace with your logic to retrieve the user's stored frequency // This could be from a database query or any other data source throw new NotImplementedException(); } } register the service public void ConfigureServices(IServiceCollection services) { // ... services.AddHostedService (); // ... } and config ythe dependency injection' public void ConfigureServices(IServiceCollection services) { // ... services.AddHttpClient(); // ... }
