用EF配置Serilog ASP.Net Core3.2以记录SQL状态

Question

以前，在使用Microsoft.Extensions.Logging时，我会在设置ILoggerFactory和.UseLoggingFactory()时注入DbContext，如下所示(简化为简洁)；

    private readonly ILoggerFactory LoggerFactory;


    public Startup(... ILoggerFactory loggerFactory)
    {
        LoggerFactory = loggerFactory ?? throw new ArgumentNullException(nameof(loggerFactory));
    }

    public void ConfigureServices(IServiceCollection services)
    {
        var connectionString = Configuration.GetConnectionString($"DbDataContext");

        services.AddDbContext<OakfieldLeasingDataContext>(
            options => options
                .UseSqlServer(
                    connectionString,
                    x => x.UseNetTopologySuite())
                .UseLoggerFactory(LoggerFactory));
     }

我现在正试图在Serilog中交换，我已经成功地更改了我的Program.cs如下；

    public static void Main(string[] args)
    {
        Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Debug()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Information)
        .Enrich.FromLogContext()
        .WriteTo.Console(new RenderedCompactJsonFormatter())
        .WriteTo.File(new RenderedCompactJsonFormatter(), "./logs/log.ndjson")
        .CreateLogger();

        try
        {
            Log.Information("Starting up");
            CreateHostBuilder(args).Build().Run();
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "Application start-up failed");
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }

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

并且可以成功地确认日志是否进入日志文件。但是，对于现有的代码，我会得到以下错误；

System.InvalidOperationException:在试图激活‘Bazor.Server.Startup’时，无法解析“Microsoft.Extensions.Logging.ILoggerFactory”类型的服务。

有人能告诉我如何将Serilog LoggerFactory注入到anyone以记录SQL生成吗？

Answer 1

Program.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSerilog()
                .MinimumLevel.Override("Microsoft.EntityFrameworkCore", Serilog.Events.LogEventLevel.Information)
                    .WriteTo.Console(restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Verbose))

您需要以以下方式包含DB上下文：

services.AddDbContext<OakfieldLeasingDataContext>(
        options => options
            .UseSqlServer(
                connectionString,
                x => x.UseNetTopologySuite())
            .LogTo(Log.Logger.Information, LogLevel.Information, null));
