(精華2020年6月17日更新)asp.net core3.1實戰專題 Worker Service構建系統服務實現任務調度

使用vs2019創建Worker Service程序

首先nuget安裝

Microsoft.Extensions.Hosting.Windows

在Program中添加UseWindowsService()

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

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddHostedService<Worker>();
                }).UseWindowsService();//部署windows值守服務
    }

實際任務執行代碼Worker類

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

        public Worker(ILogger<Worker> logger)
        {
            _logger = logger;
        }

        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                //實際要執行的任務代碼
                await Task.Delay(8640000, stoppingToken);
            }
        }
    }

發佈程序後在程序目錄用cmd執行以下代碼

sc.exe create 服務名稱 binpath= xxxx.exe
