本文介绍了如何从.Net Core 2.1 / 2.2制作Windows服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

最近我需要将.Net Core 2.1或2.2控制台应用程序转换为Windows服务。

Recently I had a need to convert a .Net Core 2.1 or 2.2 console application into a Windows Service.

由于我不需要移植此端口进程到Linux，我可以省去我在Stackoverflow上看到的涉及.Net Framework，.Net Standard和.Net Core任意组合的多平台解决方案。

As I didn't have a requirement to port this process to Linux, I could dispense with the multiple platform solutions that I had seen on Stackoverflow that dealt with any combination of .Net Framework, .Net Standard and .Net Core.

进行了一些挖掘和提供了很多帮助，使我有了一些行之有效的方法：

A bit of digging and much help I had something that worked:

推荐答案

在本文中，我将介绍设置的必要步骤将.Net Core 2.1或2.2进程作为Windows服务。由于我对Linux没有要求，因此我可以寻找针对Windows的解决方案。有点挖掘，发现了史蒂夫·戈登（Steve Gordon）的一些帖子（谢谢！），特别是在他展示Microsoft.Extensions.Hosting软件包和Windows托管的地方（单击此处（用于发帖），此处（用于他的github示例）。以下是所需步骤：

In this post I will describe the steps required to set up a .Net Core 2.1 or 2.2 process as a Windows Service. As I have no requirement for Linux, I could look for a solution that was Windows-specific. A bit of digging turned up some posts from Steve Gordon (thanks!), in particular where he presents the Microsoft.Extensions.Hosting package and Windows hosting ( click here for post and here for his github sample ). Here are the steps required:

首先创建.Net核心控制台应用程序。
将语言版本设置为至少7.1，以支持Main方法的异步任务。（从项目设置-> Build-> Advanced-> Language Settings中访问语言版本。
添加Microsoft.Extensions.Hosting和System.ServiceProcess.ServiceController程序包。
编辑项目.csproj文件，并将其包含在PropertyGroup中：< RuntimeIdentifier> win7-x64< / RuntimeIdentifier>
确保您已经在PropertyGroup< OutputType> Exe< / OutputType>

First create a .Net Core console application.
Set the language version to at least 7.1 to support async Task for the Main method. (Access the language version from the project settings->Build->Advanced->Language Settings.
Add the Microsoft.Extensions.Hosting and the System.ServiceProcess.ServiceController packages.
Edit the project .csproj file and include in the PropertyGroup: <RuntimeIdentifier>win7-x64</RuntimeIdentifier>
Insure you have in the PropertyGroup <OutputType>Exe</OutputType>

现在转到Program.cs并复制以下内容：

Now go to Program.cs and copy the following:

using System.Diagnostics; using System.Linq; using System.Threading.Tasks; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; namespace AdvancedHost { internal class Program { private static async Task Main(string[] args) { var isService = !(Debugger.IsAttached || args.Contains("--console")); var builder = new HostBuilder() .ConfigureServices((hostContext, services) => { services.AddHostedService<LoggingService>(); }); if (isService) { await builder.RunAsServiceAsync(); } else { await builder.RunConsoleAsync(); } } } }

此代码将支持交互式调试和生产执行，并运行示例类LoggingService。这是服务本身的骨架示例：

This code will support interactive debugging and production execution, and runs the example class LoggingService. Here is a skeleton example of the service itself:

using Microsoft.Extensions.Configuration; using Microsoft.Extensions.Hosting; using System; using System.IO; using System.Threading; using System.Threading.Tasks; using System.Collections.Concurrent; namespace AdvancedHost { public class LoggingService : IHostedService, IDisposable { public Task StartAsync(CancellationToken cancellationToken) { // Startup code return Task.CompletedTask; } public Task StopAsync(CancellationToken cancellationToken) { // Stop timers, services return Task.CompletedTask; } public void Dispose() { // dispose of non-managed resources } } }

完成项目所需的最后两个文件：

The final two files necessary to complete the project:

ServiceBaseLifetime.cs：

ServiceBaseLifetime.cs:

using Microsoft.Extensions.Hosting; using System; using System.ServiceProcess; using System.Threading; using System.Threading.Tasks; namespace AdvancedHost { public class ServiceBaseLifetime : ServiceBase, IHostLifetime { private readonly TaskCompletionSource<object> _delayStart = new TaskCompletionSource<object>(); public ServiceBaseLifetime(IApplicationLifetime applicationLifetime) { ApplicationLifetime = applicationLifetime ?? throw new ArgumentNullException(nameof(applicationLifetime)); } private IApplicationLifetime ApplicationLifetime { get; } public Task WaitForStartAsync(CancellationToken cancellationToken) { cancellationToken.Register(() => _delayStart.TrySetCanceled()); ApplicationLifetime.ApplicationStopping.Register(Stop); new Thread(Run).Start(); // Otherwise this would block and prevent IHost.StartAsync from finishing. return _delayStart.Task; } private void Run() { try { Run(this); // This blocks until the service is stopped. _delayStart.TrySetException(new InvalidOperationException("Stopped without starting")); } catch (Exception ex) { _delayStart.TrySetException(ex); } } public Task StopAsync(CancellationToken cancellationToken) { Stop(); return Task.CompletedTask; } // Called by base.Run when the service is ready to start. protected override void OnStart(string[] args) { _delayStart.TrySetResult(null); base.OnStart(args); } // Called by base.Stop. This may be called multiple times by service Stop, ApplicationStopping, and StopAsync. // That's OK because StopApplication uses a CancellationTokenSource and prevents any recursion. protected override void OnStop() { ApplicationLifetime.StopApplication(); base.OnStop(); } } }

ServiceBaseLifetimeHostExtensions.cs：

ServiceBaseLifetimeHostExtensions.cs:

using System.Threading; using System.Threading.Tasks; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; namespace AdvancedHost { public static class ServiceBaseLifetimeHostExtensions { public static IHostBuilder UseServiceBaseLifetime(this IHostBuilder hostBuilder) { return hostBuilder.ConfigureServices((hostContext, services) => services.AddSingleton<IHostLifetime, ServiceBaseLifetime>()); } public static Task RunAsServiceAsync(this IHostBuilder hostBuilder, CancellationToken cancellationToken = default) { return hostBuilder.UseServiceBaseLifetime().Build().RunAsync(cancellationToken); } } }

要安装，请运行或删除我使用'sc'实用程序的服务：

In order to install, run or delete the service I use the 'sc' utility:

sc create AdvancedHost binPath="C:\temp\AdvancedHost\AdvancedHost.exe"

其中 AdvancedHost 是服务名称， binPath 的值是已编译的可执行文件。

where AdvancedHost is the service name and the value for binPath is the compiled executable.

一旦创建了服务，就开始：

Once the service is created, to start:

sc start AdvancedHost

要停止：

sc stop AdvancedHost

，最后删除（一次停止）：

and finally to delete (once stopped):
