我在2013年的visual studio中使用了xamarin ..感谢您的帮助。如果使用这个Newtonsoft.Json.JsonSerializer是我的问题。我可以提供一些小样本代码吗?感谢

您可以使用JsonConvert.Deserialize将json转换为自定义对象。
public class RootObject
{
public int id { get; set; }
public string sub_category_name { get; set; }
public int child_level { get; set; }
public int has_child { get; set; }
public string sub_parent_url { get; set; }
}
class Program
{
static void Main(string[] args)
{
WebRequest objRequest = HttpWebRequest.Create(dest);
WebResponse objResponse = objRequest.GetResponse();
using (StreamReader reader = new StreamReader(objResponse.GetResponseStream()))
{
string jsonString = reader.ReadToEnd();
var data = JsonConvert.DeserializeObject<List<RootObject>>(jsonString);
}
}
}
