好吧，如果您查看以下代码，基本上我已经向 google api 发出了一个网络请求，该请求将日历信息作为字符串返回，但我在访问嵌套的 Json 数据时遇到了问题。我做了很多搜索，老实说我完全迷路了。这是我发出网络请求并将 Json 数据传递给字符串的代码:
WebRequest request = WebRequest.Create("http://www.google.com/calendar/feeds/developer-calendar@google.com/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();
但是一旦我有了包含 Json 数据的字符串，我似乎只能使用我的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 数据的最佳方式是什么......上面的网络请求中提供的 url 应该有效。
另外，我在 Xamarin studio 工作，所以我使用 Newtonsoft.Json 进行反序列化。
最佳答案
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/ ) 或者 http://jsonpack.com/ModelGenerators/CSharp
主要问题是您似乎有无效的 csharp 变量名。
像这样:
// Json Mapping Automatically Generated By JsonToolkit Library for C#
// Diego Trinciarelli 2011
// To use this code you will need to reference Newtonsoft's Json Parser, downloadable from codeplex.
// http://json.codeplex.com/
//

using Newtonsoft.Json;

public string Serialize()
{
return JsonConvert.SerializeObject(this);
}
public static MyMainClass FromJson(string json)
{
return JsonConvert.DeserializeObject<MyMainClass>(json);
}
