我正在尝试反序列化来自 Google Places Api 的 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<PlacesResult>(json);
我得到 resultz.status = "确定" 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。
最佳答案
我使用这个网站从一个随机的 Json 文件中得出我的类结构。 http://json2csharp.com/
这是一个起点,但它应该对本文的其他浏览者更有用,而不仅仅是简单地为您修复类:)
