当我使用json.net反序列化json时

类看起来没问题，反序列化工作正常。哪里有问题？

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

public class AddressComponent
   {
       public string long_name { get; set; }
       public string short_name { get; set; }

        GeoCodingModel ro = JsonConvert.DeserializeObject<GeoCodingModel>(j);

        Console.WriteLine(ro.results[0].geometry.location_type);

    }
