配置 Serilog 从应用程序 json 文件读取会出现异常 System.InvalidOperationException: 'Type Sample.CustomPolicy, Sample was not find.'

Question

我是 Serilog 新手，一直在尝试一些代码来使用基于 GitHub 包的应用程序设置 Json 文件来配置 Serilog (https://github.com/serilog/serilog-settings-configuration)。

我有一个 .NET 7.0 控制台应用程序。我添加了以下 NuGet 包。

• Microsoft.扩展.配置
• Microsoft.Extensions.Configuration.Json
• Microsoft.Extensions.Configuration.Xml Serilog
• Serilog.Enrichers.Environment
• Serilog.Enrichers.Thread
• Serilog.设置.配置
• Serilog.Sinks.Console
• Serilog.Sinks.File

appsettings.json的内容是

{
  "Appsettings": {
    "client_id": "",
    "client_secret": ""
  },
  "Serilog": {
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      { "Name": "Console" },
      {
        "Name": "File",
        "Args": { "path": "Logs/log.txt" }
      }
    ],
    "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
    "Destructure": [
      {
        "Name": "With",
        "Args": { "policy": "Sample.CustomPolicy, Sample" }
      },
      {
        "Name": "ToMaximumDepth",
        "Args": { "maximumDestructuringDepth": 4 }
      },
      {
        "Name": "ToMaximumStringLength",
        "Args": { "maximumStringLength": 100 }
      },
      {
        "Name": "ToMaximumCollectionCount",
        "Args": { "maximumCollectionCount": 10 }
      }
    ]
  }
}

在 Program.cs Main 函数中，代码是

var ConfigBuilder = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
var logger = new LoggerConfiguration().ReadFrom.Configuration(ConfigBuilder).CreateLogger();

代码语句

var logger = LoggerConfiguration().ReadFrom.Configuration(ConfigBuilder).CreateLogger()

给出了异常

System.InvalidOperationException
  HResult=0x80131509
  Message=Type Sample.CustomPolicy, Sample was not found.
  Source=Serilog.Settings.Configuration
  StackTrace:

不确定我错过了什么或做错了什么。任何帮助将不胜感激。

Answer 1

{
  "Name": "With",
  "Args": { "policy": "Sample.CustomPolicy, Sample" }
},

这部分来自示例。只需将其删除即可。
