我有一些JSON数据,如下所示:
{
"response":{
"_token":"StringValue",
"code":"OK",
"user":{
"userid":"2630944",
"firstname":"John",
"lastname":"Doe",
"reference":"999999999",
"guid":"StringValue",
"domainid":"99999",
"username":"jdoe",
"email":"jdoe@jdoe.edu",
"passwordquestion":"",
"flags":"0",
"lastlogindate":"2013-02-05T17:54:06.31Z",
"creationdate":"2011-04-15T14:40:07.22Z",
"version":"3753",
"data":{
"aliasname":{
"$value":"John Doe"
},
"smsaddress":{
"$value":"5555555555@messaging.sprintpcs.com"
},
"blti":{
"hideemail":"false",
"hidefullname":"false"
},
"notify":{
"grades":{
"$value":"0"
},
"messages":{
"$value":"1"
}
},
"beta_component_courseplanexpress_1":{
"$value":"true"
}
}
}
}
我正在使用C#和JSON.NET来解析数据。我已经能够使用这种算法成功获取数据:
User MyUser = new User();
JToken data = JObject.Parse(json);
MyUser.FirstName = (string) data.SelectToken("response.user.firstname");
//The same for all the other properties.
问题在于data
字段。该字段主要基于用户首选项,并且仅在使用时插入数据。这些字段都是自定义的,开发人员可以无限制地放入任意数量的字段。从本质上讲,它是所有自由格式数据。另外,正如您所注意到的那样,它们可以与数据完全嵌套。
我试图跑:
MyUser.Data = JsonConvert.DeserializeObject<List<JToken>>((string) data.SelectToken("response.user.data");
哪个不起作用。
如何将其转换为在C#对象中使用?

如果对您有用,Json.NET实际上可以解析为动态。 这意味着你可以做类似的事情。
dynamic parsedObject = JsonConvert.DeserializeObject("{ test: \"text-value\" }");
parsedObject["test"]; // "text-value"
parsedObject.test; // "text-value"
parsedObject.notHere; // null
编辑:如果你不知道你在寻找什么,可能更适合你迭代这些值。
dynamic parsedObject = JsonConvert.DeserializeObject("{ test: { inner: \"text-value\" } }");
foreach (dynamic entry in parsedObject)
{
string name = entry.Name; // "test"
dynamic value = entry.Value; // { inner: "text-value" }
}

您可以通过JToken
/ JArray
/ JObject
方法访问它。例如,这将列出数据下的所有键:

public static void Test()
{
var jo = JObject.Parse(JSON);
var data = (JObject)jo["response"]["user"]["data"];
foreach (var item in data)
{
Console.WriteLine("{0}: {1}", item.Key, item.Value);
}
}
