有什么方法可以覆盖 Serilog 中 json 配置中的代码编写记录器

Question

I have this code written:

 return Host.CreateDefaultBuilder()
                .UseSerilog((context, services, configuration) => configuration
                    .MinimumLevel.Verbose()
                    .ReadFrom.Configuration(_configuration)
                    .ReadFrom.Services(services)
                    .Enrich.FromLogContext()
                    .Enrich.With(UserLoginEnricher.GetInstance()) 
                    .Enrich.With(new LoggersAdditionalEnricher())
 //CSV logger
                    .WriteTo.Logger(x =>
                    {
                        x.WriteTo.File(ApplicationConfiguration.FullPathToCsvFile,
                            rollingInterval: RollingInterval.Day, 
                            encoding: Encoding.Unicode, 
                            retainedFileCountLimit: ApplicationConfiguration.AppSettingsOptions.RetainDataCount, 
                            outputTemplate: "{Message}{NewLine}");

                        //log filter
                        x.Filter.ByIncludingOnly(e =>
                        {
                            if (!e.Properties.ContainsKey(nameof(LogType)))
                                return false;
                            return e.Properties[nameof(LogType)].ToString() == LogType.CSV.ToString();
                        });
                    })
                    .WriteTo(x =>{...})
                    .WriteTo(x =>{...});

Is there any way to configure json SERILOG configuration to change minimum level of File logger without code changes?

My JSON config of serilog:

"Serilog": {
    "Using": [
      "Serilog.Sinks.File"
    ],
    "MinimumLevel": {
      "Default": "Verbose",
      "Override": {
        "Microsoft": "Warning",
        "Microsoft.EntityFrameworkCore.Database.Command": "Warning"
        }
    }
  }

I have more loggers. I need all loggers to write with Warning level and this CSV logger to write on Information level

You can use this nuget package for doing configuration in appsettings.json for Serilog. https://github.com/serilog/serilog-settings-configuration

and there great extension which even helps us to convert code to proper configuration. https://marketplace.visualstudio.com/items?itemName=Suchiman.SerilogAnalyzer

and to restrict log level for a particular sink you can specify like this

"WriteTo": [
      {
        "Name": "File",
        "Args": { "restrictedToMinimumLevel": "Information" }
      }
    ]

you need to add other arguments as per your requirement.

Hope it helps.
