我试图从Google Places Api反序列化这个Json响应.这是json:

以下是我将尝试反序列化的对象:
public class PlacesResult { public string Status { get; set; } public Prediction[] Preditions { get; set; } } public class Prediction { public string description { get; set; } public string id { get; set; } public matched_substring[] matched_substrings { get; set; } public string reference { get; set; } public Terms[] terms { get; set; } public Types types { get; set; } } public class Terms { public string offset { get; set; } public string value { get; set; } } public class Types { public string[] types { get; set; } } public class matched_substring { public int length { get; set; } public int offset { get; set; } }
这是我的代码(使用NewtonSoft json.NET)
json = new System.Net.WebClient().DownloadString(url); PlacesResult resultz = JsonConvert.DeserializeObject(json);
我得到resultz.status ="OK"resultz.predictions = null.
我在预测结构上犯了一个错误,但我不确定是什么?请帮忙.
