如何将appsettings.json绑定到类？

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

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

public IConfiguration Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<DatabaseSettings>(Configuration.GetSection("Database"));
    // 其他服务配置...
}

public class MyClass
{
    private readonly DatabaseSettings _databaseSettings;

    public MyClass(IOptions<DatabaseSettings> databaseSettings)
    {
        _databaseSettings = databaseSettings.Value;
    }

    public void DoSomething()
    {
        string connectionString = _databaseSettings.ConnectionString;
        // 使用配置值...
    }
}
