我在使用JSON.NET库对从Facebook返回的数据进行反序列化时遇到了一些麻烦.

从简单的墙贴文件返回的JSON看起来像:

{
    "attachment":{"description":""},
    "permalink":"http://www.facebook.com/permalink.php?story_fbid=123456789"
}

为照片返回的JSON如下所示:

"attachment":{
        "media":[
            {
                "href":"http://www.facebook.com/photo.php?fbid=12345",
                "alt":"",
                "type":"photo",
                "src":"http://photos-b.ak.fbcdn.net/hphotos-ak-ash1/12345_s.jpg",
                "photo":{"aid":"1234","pid":"1234","fbid":"1234","owner":"1234","index":"12","width":"720","height":"482"}}
        ],

一切都很好,我没有问题.我现在遇到一个来自移动客户端的简单墙帖,其中包含以下JSON,现在反序列化失败,只有一个帖子:

"attachment":
    {
        "media":{},
        "name":"",
        "caption":"",
        "description":"",
        "properties":{},
        "icon":"http://www.facebook.com/images/icons/mobile_app.gif",
        "fb_object_type":""
    },
"permalink":"http://www.facebook.com/1234"

这是我反序列化的类:

public class FacebookAttachment
    {
        public string Name { get; set; }
        public string Description { get; set; }
        public string Href { get; set; }
        public FacebookPostType Fb_Object_Type { get; set; }
        public string Fb_Object_Id { get; set; }

        [JsonConverter(typeof(FacebookMediaJsonConverter))]
        public List<FacebookMedia> { get; set; }

        public string Permalink { get; …
