如何在web请求后用c#反序列化复杂的嵌套Json数据

Question

好的，所以本质上，如果你看看下面的代码，我已经做了一个web请求的谷歌api，返回日历信息作为一个字符串，但我有麻烦访问嵌套Json数据。我做了很多搜索，老实说，我完全迷路了。以下是我发出web请求并将Json数据传递给字符串的代码:

WebRequest request = WebRequest.Create("http://www.google.com/calendar/feeds/[e-mail]/public/full?alt=json");
request.Credentials = CredentialCache.DefaultCredentials;
request.ContentType = "application/json";
WebResponse response = request.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader (dataStream);
string responseFromServer = reader.ReadToEnd();

但是一旦我有包含Json数据的字符串，我似乎只能用以下类访问版本和编码组件:

    public class calendarData
    {
        public string version { get; set; }
        public string encoding { get; set; }
        public string feed { get; set; }
    }

所以，我想我的问题是在这个请求的情况下访问嵌套json数据的最好方法是什么…上述web请求中提供的url应该可以工作。

另外，我在Xamarin工作室工作，所以我使用Newtonsoft。Json来做反序列化

Answer 1

将其反序列化为RootObject类型的对象，然后访问属性/字段。

你可以使用http://json2csharp.com/)或http://jsonpack.com/ModelGenerators/CSharp

生成json类

主要的问题是你似乎有无效的csharp变量名。
