修改 Program.cs

using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

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

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            })
            .ConfigureServices(services =>
            {
                services.AddHostedService<VideosWatcher>();
            });
}

修改后

    public class Program
    {
        public static void Main(string[] args)
        {
            HostFactory.Run(x =>
            {
                x.SetServiceName("TopshelfDemo.ServiceName");
                x.SetDisplayName("TopshelfDemo.DisplayName");
                x.SetDescription("TopshelfDemo.Description");

                x.Service<IHost>(s =>
                {
                    s.ConstructUsing(() => CreateHostBuilder(args).Build());
                    s.WhenStarted(service =>
                    {
                        service.Start();
                    });
                    s.WhenStopped(async service =>
                    {
                        await service.StopAsync();
                    });
                });
                x.StartAutomatically();
            });
        }

        const string OutputInfoTemplate = "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}{NewLine}";
        const string OutputPropTemplate = "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Properties:l}{NewLine}{Exception}{NewLine}";

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args)
#if DEBUG
                .UseEnvironment(Environments.Development)
#else
                .UseEnvironment(Environments.Staging)
                //.UseEnvironment(Environments.Production)
#endif
                .UseContentRoot(AppContext.BaseDirectory)
                .UseSerilog((hostingContext, loggerConfiguration) =>
                {
                    loggerConfiguration
                        .ReadFrom.Configuration(hostingContext.Configuration)
                        .Enrich.WithExceptionDetails()
                        .Enrich.FromLogContext()
                        .WriteTo.Debug()
                        .WriteTo.Console(theme: SystemConsoleTheme.Colored)
                        .WriteTo.File(AppContext.BaseDirectory + "log/log.txt",
                            outputTemplate: OutputInfoTemplate, rollingInterval: RollingInterval.Day)
                        .WriteTo.File(AppContext.BaseDirectory + "log/error.txt", LogEventLevel.Warning,
                            outputTemplate: OutputPropTemplate, rollingInterval: RollingInterval.Day);
                })
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddHostedService<Worker>();
                });
    }

这里我使用 Serilog 作为日志系统
通过修改 outputTemplate 来输出想要 log 文件
效果如下

运行时效果如下：

有颜色显示的控制台还是不错的
