.NET Core使用Worker Service创建服务

    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();

                .UseWindowsService()
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddHostedService<Worker>(); 
                });
    }

public class Worker : BackgroundService
    {
        private readonly ILogger<Worker> _logger;

        public Worker(ILogger<Worker> logger)

        }

            while (!stoppingToken.IsCancellationRequested)
            {
                _logger.LogInfORMation("Worker running at: {time}", DateTimeOffset.Now);
                await Task.Delay(1000, stoppingToken);
            }
        }
    }

        public virtual void Dispose();
        public virtual Task StartAsync(CancellationToken cancellationToken);
        public virtual Task StopAsync(CancellationToken cancellationToken);
