Serilog 配置提供者源码下载：从 Microsoft.Extensions.Configuration 读取配置

【实例简介】
Serilog.Settings.Configuration 是一个能够从 Microsoft.Extensions.Configuration 源读取设置的 Serilog 设置提供者，这包括了 .NET Core 的 appsettings.json 文件。默认情况下，配置是从 Serilog 部分读取的。
以下是一个配置示例：

{
  "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 } }
    ],
    "Properties": {
        "Application": "Sample"
    }
  }
}

安装此包后，使用 ReadFrom.Configuration() 并传递一个 IConfiguration 对象。
以下是一个使用示例：

static void Main(string[] args)
{
    var configuration = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appsettings.json")
        .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", true)
        .Build();

    var logger = new LoggerConfiguration()
        .ReadFrom.Configuration(configuration)
        .CreateLogger();

    logger.Information("Hello, world!");
}

这个例子依赖于 Microsoft.Extensions.Configuration.Json, Serilog.Sinks.Console, Serilog.Sinks.File, Serilog.Enrichers.Environment 和 Serilog.Enrichers.Thread 包也被安装。更复杂的例子可以在示例文件夹中找到。
