反序列化JSON与嵌套选择

Question

我的问题POCO类是什么，我都问here

我只是想JSON数据deserilize到C＃定制POCO类，如下图所示，在这里延续是我已经这样做了远;

public static UserItem DownloadJSONString(string urlJson) 
{ 
    var root = JsonConvert.DeserializeObject<RootObject>(json); 
    var userItem = root.results 
         .Select(i => new UserItem 
         { 
          id = i.id, 
          name = i.name, 
          title = i.title, 

          //tried using `Any` but does not seems work... 
          audience = (from _tag in root.results.SelectMany(x => x.tags) //<<< 
             select new Audience { id = _tag.Id .....}).ToList() 

         }).ToList(); 

     return userItem;   
} 

这里是我的JSON对象（生成JSON到C＃类）

public class Tags 
{ 
    public List<object> audience { get; set; } 
}  

public class Results 
{ 
    public int id { get; set; } 
    public string name { get; set; } 
    public Tags tags { get; set; } 
} 

public class RootObject 
{ 
    public Meta meta { get; set; } 
    public Results results { get; set; } 
} 

这里是我的简单UserItem POCO类

public class UserItem 
{ 
    public int id { get; set; } 
    public string name { get; set; } 
    public string title { get; set; } 
    public Audience audience { get; set; } 
} 

public class Audience 
{ 
    public int id { get; set; } 
    public string name { get; set; } 
}
