為什么 Serilog selflog 在這個簡單的 windows 服務中不起作用？

Question

我無法讓 Serilog selflog 在我的 .NET Core 6.0 C# Windows 服務中工作。 這是 Main 的樣子：

public static void Main(string[] args)
        {
            Serilog.Debugging.SelfLog.Enable(msg => System.Diagnostics.Debug.WriteLine($"Seri-serlflog : {msg}"));

            Log.Logger = new LoggerConfiguration().DefaultLoggerSetup<Program>();
            var serviceName = "MyService";

            var configurationBuilder = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
            var appSettings = configurationBuilder.Get<AppSettings>();

            try
            {
                Log.Information("{@serviceName} microservice starting up.", serviceName);
                
                var built = Host.CreateDefaultBuilder(args)
                    .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration.ReadFrom.Configuration(hostingContext.Configuration))
                    .ConfigureServices((hostContext, services) =>
                    {
                        services
                            .AddHostedService<MyApp.Cloud.MyService.BusinessLogicLayer.MyService>()
                            .Configure<MySettings>(configurationBuilder.GetSection("MQSettings"))
                            .AddAutoMapper(typeof(ConnectorToCloudTreatment))
                            .AddTransi...
                    }).Build();
                Log.Information("{@serviceName} all built.", serviceName);
                built.Run();
                Log.Information("{@serviceName} microservice closing down.", serviceName);
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Unhanled exception in {@serviceName}.", serviceName);
            }
            finally
            {
                Log.Information("{@serviceName} Cleaning up.", serviceName);
                Log.CloseAndFlush();
                Log.Information("{@serviceName} Application Exit.", serviceName);
            }
        }
    }

application.json 的 serilog 部分如下所示：

  "serilog": {
    "Using": [ "Serilog.Sinks.MSSqlServer", "Serilog.Sinks.Email" ],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "Enrich": [ "FromLogContext", "WithMachineName", "WithProcessId" ],
    "WriteTo": [
      {
        "Name": "Console",
        "Args": {
          "outputTemplate": "[{Timestamp:HH:mm:ss.fff} [{Level}] {SourceContext} {Message}{NewLine}{Exception}",
          "theme": "Serilog.Sinks.SystemConsole.Themes.AnsiConsoleTheme::Code, Serilog.Sinks.Console"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "/Logs/logs.txt",
          "outputTemplate": "{Timestamp:G} {SourceContext} [{Level}] {Message}{NewLine:1}{Exception:1}",
          "formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog",
          "fileSizeLimitBytes": 1000000,
          "rollOnFileSizeLimit": "true",
          "shared": "true",
          "flushToDiskInterval": 3
        }
      }
    ]
  }

我在這個應用程序中做了很多日志記錄並且它工作正常但是有幾個問題並且找到為什么我需要使用 selflog 但我沒有獲得任何信息到 output > 調試？

編輯：似乎這可能與注射有關。 在 program.cs 中，我使用 static 日志，但在所有其他類中，我使用注入類型的記錄器。 但無論如何，我應該在 output 中得到幾行 $"Seri-serlflog: {msg}" 嗎？

如果您正在嘗試獲取調試級別的日志記錄，則必須放寬您的日志級別：

"MinimumLevel": {
      "Default": "Debug",
      "Override": {
        "Microsoft": "Debug",
        "System": "Debug"
      }
