在阅读本文章之前,你可以先阅读:

  • Topshelf一个用于使用.NET构建Windows服务框架

2 使用

2.1 创建应用程序

首先,创建一个新的控制台应用程序并从nuget获取Topshelf和Microsoft.Extensions.Hosting软件包

Topshelf
Microsoft.Extensions.Hosting

当然我们也需要安装Serilog相关的日志框架。

Serilog.Extensions.Hosting
Serilog.Settings.Configuration
Serilog.Sinks.Console
Serilog.Sinks.File
Topshelf.Serilog

2.2 创建.NET泛型主机

然后,我们先建立CreateHostBuilder()方法,并加载了Serilog日志并依赖注入MyService和AppSettings,MyService类做为Topshelf所使用的主要逻辑程序,它会提供Start()和Stop()做为Topshelf执行或停止主要逻辑程序的动作。

class Program
{
    static void Main(string[] args)
    {
        var host = CreateHostBuilder(args).Build();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args)
            .UseSerilog()
            .ConfigureServices((hostContext, services) =>
            {
                services.Configure<AppSettings>(hostContext.Configuration);
                services.AddTransient<MyService>();
            });
}

2.3 在Topshelf中注册服务

接着,在Topshelf中注册我们的服务类。跳转到Program.cs并添加:

class Program
{
    static void Main(string[] args)
    {
        var host = CreateHostBuilder(args).Build();
        RunWindowsServiceWithHost(host);
    }

    private static void RunWindowsServiceWithHost(IHost host)
    {
        var rc = HostFactory.Run(x =>
        {
            x.UseSerilog();
            x.SetDisplayName("我的服务");
            x.SetDescription("我的服务详细描述");
            x.SetServiceName("MyService");

            var myService = host.Services.GetRequiredService<MyService>();
            x.Service<MyService>(s =>
            {
                s.ConstructUsing(() => myService);
                s.WhenStarted(tc => tc.Start());
                s.WhenStopped(tc => tc.Stop());
            });
            x.RunAsLocalSystem();
            x.StartAutomatically();
        });

        var exitCode = (int)Convert.ChangeType(rc, rc.GetTypeCode());
        Environment.ExitCode = exitCode;
    }
}

2.4 MyService类

接着,我们看看MyService类,主要演示了注入ILogger和AppSettings。

public class MyService
{
    private readonly ILogger logger;
    private readonly AppSettings settings;

    public MyService(IOptions<AppSettings> settings, ILogger<MyService> logger)
    {
        this.settings = settings.Value;
        this.logger = logger;
    }
    public void Start()
    {
        logger.LogInformation($"Starting {this.settings.ServiceName}...");
    }

    public void Stop()
    {
        logger.LogInformation($"Stopping {this.settings.ServiceName}...");
    }
}
