使用 Serilog 替代默认日志记录器：

public class Program
{
    public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
        .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
        .AddEnvironmentVariables()
        .Build();
    public static int Main(string[] args)
    {
        Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
        .MinimumLevel.Debug()
        .Enrich.FromLogContext()
        .WriteTo.Console(new RenderedCompactJsonFormatter())
        .WriteTo.File(formatter: new CompactJsonFormatter(), "logs\\myapp.txt", rollingInterval: RollingInterval.Day)
        .CreateLogger();
        try
        {
            Log.Information("Starting web host");
            CreateHostBuilder(args).Build().Run();
            return 0;
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "Host terminated unexpectedly");
            return 1;
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }
    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            })
            .UseSerilog(dispose: true);
}
