如何在.NET内核中配置来自appsettings.json的嵌套对象？

{
  "DatabaseSettings": {
    "ConnectionString": "your_connection_string",
    "MaxConnections": 10
  }
}

using Microsoft.Extensions.Configuration;

var configuration = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json")
    .Build();

var databaseSettings = new DatabaseSettings();
configuration.GetSection("DatabaseSettings").Bind(databaseSettings);

public class DatabaseSettings
{
    public string ConnectionString { get; set; }
    public int MaxConnections { get; set; }
}

Console.WriteLine(databaseSettings.ConnectionString);
Console.WriteLine(databaseSettings.MaxConnections);
