写在前面

本文介绍了将.NET8.0应用程序转换成Windows服务。

需要在NuGet中获取并安装：Microsoft.Extensions.Hosting.WindowsServices 包

代码实现

using System.Runtime.InteropServices;
using WorkerService1;

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

    public static IHostBuilder CreateHostBuilder(string[] args)
    {
        var host = Host.CreateDefaultBuilder(args);
        //判断当前系统是否为windows
        if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
        {
            host.UseWindowsService();
            
        }
        return host.ConfigureServices((hostContext, services) =>
        {
            services.AddHostedService<Worker>();
        });
    }
}

 

namespace WorkerService1
{
    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)
            {
                if (_logger.IsEnabled(LogLevel.Information))
                {
                    _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
                }
                await Task.Delay(1000, stoppingToken);
            }
        }
    }
}

发布配置

 

 可以使用批处理安装服务：

@echo off 
@title 安装windows服务
@echo off 
echo= 安装服务!
@echo off  
@sc create worktest binPath= "%~dp0WorkerService1.exe"  
echo= 启动服务!
@echo off  
@sc start worktest 
@echo off  
echo= 配置服务! 
@echo off  
@sc config worktest start= AUTO  
@echo off  
echo= 成功安装、启动、配置服务!   
@pause

执行结果

 由于编码问题，中文出现了乱码，但是服务已经成功创建并配置为自动启动了。
