Question

我想使用JSon.net反序列化flickr.com photoset（参见http://www.flickr.com/services/api/flickr.photosets.getPhotos.html）我得到的JSON的一个例子是

    {
photoset: {
id: "72154517991528243",
primary: "6346929005",
owner: "9999999@N00",
ownername: "myname",
photo: [
{
id: "6340104934",
secret: "18ab51078a",
server: "6106",
farm: 7,
title: "Day #1/30 - homemade kanelbullar",
isprimary: "0"


  } 
.... lots of these photos...
],
page: 1,
per_page: 500,
perpage: 500,
pages: 1,
total: "18"
},
stat: "ok"
}

我正在使用的类是：

class FlickrSet
    {

    Photoset photoset {get;set;}
    string stat{get;set;}
}
class Photoset
{

    public string id { get; set; }
    public string primary { get; set; }
    public string owner { get; set; }
    public string ownername { get; set; }
    public List<Photo> photo { get; set; }
    public int page { get; set; }
    public int per_page { get; set; }
    public int perpage { get; set; }
    public int pages { get; set; }
    public string total { get; set; }
}

class Photo
{
    public string id { get; set; }
    public string secret { get; set; }
    public string server { get; set; }
    public int farm { get; set; }
    public string title { get; set; }
    public string isprimary { get; set; }


}

当我使用它们反序列化时：

    var s=    JsonConvert.DeserializeObject<FlickrSet>(outPut );

s两个成员都为空。

我试图匹配字符串和整数以及列表，但我可能犯了一些错误。谢谢大家！

Answer 1

有两个错误：flickrset上的属性不公开，照片是一个数组而不是List＆lt;＆gt; （不知道为什么）类FlickrSet {

    **public** Photoset photoset {get;set;}
    **public** string stat{get;set;}
}
class Photoset
{

    public string id { get; set; }
    public string primary { get; set; }
    public string owner { get; set; }
    public string ownername { get; set; }
    public **Photo[]** photo { get; set; }
    public int page { get; set; }
    public int per_page { get; set; }
    public int perpage { get; set; }
    public int pages { get; set; }
    public string total { get; set; }
}

class Photo
{
    public string id { get; set; }
    public string secret { get; set; }
    public string server { get; set; }
    public int farm { get; set; }
    public string title { get; set; }
    public string isprimary { get; set; }


}

System.Web.Script.Serialization.JavaScriptSerializer js = new system.Web.Script.Serialization.JavaScriptSerializer();
return js.Deserialize<FlickrSet>(value);

Newtonsoft JSON.NET反序列化为类型化对象
