Question

我无法弄清楚如何在.Net中编写一个用于反序列化JSON中对象列表的类。

从JSON规范中，我们了解到这是有效的JSON：

   [
      {
         "precision": "zip",
         "Latitude":  37.7668,
         "Longitude": -122.3959,
         "Address":   "",
         "City":      "SAN FRANCISCO",
         "State":     "CA",
         "Zip":       "94107",
         "Country":   "US"
      },
      {
         "precision": "zip",
         "Latitude":  37.371991,
         "Longitude": -122.026020,
         "Address":   "",
         "City":      "SUNNYVALE",
         "State":     "CA",
         "Zip":       "94085",
         "Country":   "US"
      }    ]

所以我构造了这个类来处理反序列化：

using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

namespace JsonRfc{

[Serializable]
public class Location {

    public string Precision;
    public double Latitude;
    public double Longitude;
    public string Address;
    public string City;
    public string State;
    public string Zip;
    public string Country;

    public Location(){}

    public static Location DeserializedJson(string responseJson)
    {
        JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
        return jsSerializer.Deserialize<Location>(responseJson);
    }
}

[Serializable]
public class Locations {

    public List<Location> Location;

    public Locations(){}

    public static Locations DeserializedJson(string responseJson)
    {
        JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
        return jsSerializer.Deserialize<Locations>(responseJson);
    }
}
}

尽管将有效的Json传递给方法，但反序列化的对象仍为null。

我尝试失败的其他事情包括：使Locations成为一个数组而不是一个列表（所以：public Location [] Location;），并反序列化到位置，即使Json包含一个位置数组。

那么，.Net开发人员如何期望反序列化一组对象？我希望上面的内容能够发挥作用，但事实并非如此。

只需返回一个数组

var locs = Location.DeserializedJson(json);

public class Location
{

    public string Precision;
    public double Latitude;
    public double Longitude;
    public string Address;
    public string City;
    public string State;
    public string Zip;
    public string Country;

    public static Location[] DeserializedJson(string responseJson)
    {
        JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
        return jsSerializer.Deserialize<Location[]>(responseJson);
    }
}

PS：请注意[Serializable]是不必要的。

如何反序列化没有名称的JSON数组？
