通过在JSON解析JSON.NET未知属性名称 [英] Parsing through JSON in JSON.NET with unknown property names
问题描述
我有一些JSON数据，看起来像这样：
I have some JSON Data which looks like this:
{
"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":{
"$value":"true"
}
}
}
}
我使用C＃与JSON.NET通过数据来分析。我已经能够成功地得到利用该算法数据：
I am using C# with JSON.NET to parse through the data. I've been able to sucessfully get data using this algorithm:
User MyUser = new User();
JToken data = JObject.Parse(json);
MyUser.FirstName = (string) data.SelectToken("response.user.firstname");
//The same for all the other properties.
问题是与数据字段。此字段是基于用户偏好大多并且因为它是用来数据仅插入。这些字段是所有自定义和开发人员可以把尽可能多的，因为他们想不限制。从本质上讲，它是免费的表单数据。 。另外，作为你发现他们真的可以远远的数据可以嵌套
The problem is with the data field. This field is based on user preferences mostly and data is only inserted as it is used. The fields are all custom and developers can put in as many as they want without restrictions. Essentially, it's all free form data. Also as you notice they can be nested really far with data.
我试图运行：
MyUser.Data = JsonConvert.DeserializeObject<List<JToken>>((string) data.SelectToken("response.user.data");
这是行不通的。
您会如何将其转换成可使用在C＃对象？
How would you go about converting it to be used in a C# object?
推荐答案
您可以通过访问它 JToken 。/ JArray / JObject 方法。例如，这将列出所有的数据在按键的：
You can access it via the JToken / JArray / JObject methods. For example, this will list all of the keys under the data:
public class StackOverflow_14714085
{
const string JSON = @"{
""response"": {
""_token"": ""StringValue"",
""code"": ""OK"",
""user"": {
""userid"": ""2630944"",
""firstname"": ""John"",
""lastname"": ""Doe"",
""reference"": ""999999999"",
""guid"": ""StringValue"",
""domainid"": ""99999"",
""username"": ""jdoe"",
""email"": ""jdoe@jdoe.edu"",
""passwordquestion"": """",
""flags"": ""0"",
""lastlogindate"": ""2013-02-05T17:54:06.31Z"",
""creationdate"": ""2011-04-15T14:40:07.22Z"",
""version"": ""3753"",
""data"": {
""aliasname"": {
""$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""
}
}
}
}
}";
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);
}
}
}
