使用vs2019创建Worker Service程序

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
   
    ();                }).UseWindowsService();//部署windows值守服务    }
   

实际任务执行代码Worker类

public class Worker : BackgroundService    {
           private readonly ILogger
   
     _logger;        public Worker(ILogger
    
      logger)        {
               _logger = logger;        }        protected override async Task ExecuteAsync(CancellationToken stoppingToken)        {
               while (!stoppingToken.IsCancellationRequested)            {
                   //实际要执行的任务代码                await Task.Delay(8640000, stoppingToken);            }        }    }
    
   

发布程序后在程序目录用cmd执行以下代码

sc.exe create 服务名称 binpath= xxxx.exe
