JSON .net Multiple objects outside an array

JSON .net Multiple objects outside an array - c#

The TrackIt Web API (I can't change it) gives me this JSON inside a return object:
...
Notes: {
Note1: {
CreatedBy: "smarteam2"
...
},
Note2: {
CreatedBy: "smarteam2"
CreatedDate: "1/27/2014 2:37:36 PM"
...
}, ...
Where there are N number of notes. I can't figure out how to deserialize this using JSON.Net unless I do something that feels wrong like:
public class TrackItWorkOrderNotes
{
public TrackItWorkOrderNotes Note1 { get; set; }
public TrackItWorkOrderNotes Note2 { get; set; }
public string IsPrivate { get; set; }
public string FullText { get; set; }
public string WorkOrderNoteTypeId { get; set; }
}
And in the parent:
public class TrackitWorkOrder
{
public TrackItWorkOrderNotes Notes { get; set; }
public int Id { get; set; }
...
This "works" by using :
ti = JsonConvert.DeserializeObject<TrackItResponse<TrackitWorkOrder>>(responseString);
I think there must be a better way to get the notes without pre-defining N number of them in the object. I believe TrackIt might have made this difficult by not putting the "Notes" in an array, but is there a smarter way to do this?

Use a Dictionary<string, Note> for the notes:
public class TrackitWorkOrder
{
public Dictionary<string, TrackItWorkOrderNote> Notes { get; set; }
public int Id { get; set; }
...
}
public class TrackItWorkOrderNote
{
public string CreatedBy { get; set; }
public string CreatedDate { get; set; }
...
}

How to generate a JSON class with dynamic name

I don't know if there is an existing name for that case, but I'm trying to retrieve data from NASA API (https://api.nasa.gov/) and I have a simple challenge to catch a list of objects near earth. Here is the JSON response I have from the GET request I do to "https://api.nasa.gov/neo/rest/v1/feed?...."
{
"links": {
"next": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-04&end_date=2021-07-04&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym",
"prev": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-02&end_date=2021-07-02&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym",
"self": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-03&end_date=2021-07-03&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym"
},
"element_count": 6,
"near_earth_objects": {
"2021-07-03": [
{
"links": {
"self": "http://www.neowsapp.com/rest/v1/neo/3701710?api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym"
},
"id": "3701710",
"neo_reference_id": "3701710",
"name": "(2014 WF497)",
"nasa_jpl_url": "http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=3701710",
"absolute_magnitude_h": 20.23,
"estimated_diameter": {
"kilometers": {
}
And that's the way it is built in Visual Studio (using the Special Paste option for JSON)
public class NearEarthObject
{
public Links links { get; set; }
public int element_count { get; set; }
public Near_Earth_Objects near_earth_objects { get; set; }
}
public class Links
{
public string next { get; set; }
public string prev { get; set; }
public string self { get; set; }
}
public class Near_Earth_Objects
{
public _20210703[] _20210703 { get; set; }
}
public class _20210703
{
public Links1 links { get; set; }
public string id { get; set; }
public string neo_reference_id { get; set; }
public string name { get; set; }
public string nasa_jpl_url { get; set; }
public float absolute_magnitude_h { get; set; }
public Estimated_Diameter estimated_diameter { get; set; }
public bool is_potentially_hazardous_asteroid { get; set; }
public Close_Approach_Data[] close_approach_data { get; set; }
public bool is_sentry_object { get; set; }
}
The question is, inside of the element "near_earth_objects", there is an element called "2021-07-03" (the date of the data I requested), the problem is that I am trying to include it into a DataGridView made in .NET C# (Windows Forms, but that doesn't matters here, I think) and the user wants to get the information by date. So, "2021-07-03" is a valid member just for one day, and the user should be able to get data from multiple days.
So, is there a way in C# to get all child objects inside of near_earth_objects without knowing their names since there will be the option to search for asteroids from date X to Y in my application?

Using System.Text.Json
The API response will map to the following classes
public class Neo
{
public Links Links { get; set; }
public int ElementCount { get; set; }
public Dictionary<string, List<NearEarthObject>> NearEarthObjects { get; set; }
}
public class Links
{
public string Next { get; set; }
public string Prev { get; set; }
public string Self { get; set; }
}
public class NearEarthObject
{
public Links Links { get; set; }
public string Id { get; set; }
public string Name { get; set; }
// Other properties
}
The NearEarthObjects is simply a Dictionary, where the key is the formatted date and value is a List containing NearEarthObject
The PropertyNamingPolicy will allow us to support the API's underscore property naming convention.
public class UnderscoreNamingPolicy : JsonNamingPolicy
{
public override string ConvertName(string name)
{
return name.Underscore();
}
}
Example usage
// using using System.Text.Json;
var response = await new HttpClient().GetStringAsync(url);
var neo = JsonSerializer.Deserialize<Neo>(response, new JsonSerializerOptions
{
PropertyNamingPolicy = new UnderscoreNamingPolicy()
});
foreach(var neos in neo.NearEarthObjects)
{
Console.WriteLine(neos.Key);
}

use System.Text.Json, JsonNamingPolicy
demo code
public class DynamicNamePolicy : JsonNamingPolicy
{
public override string ConvertName(string name)
{
var today = DateTime.Today.ToString("yyyy-MM-dd");
if (name.Equals("DateData")) //model property name
return today; //convert to json string property name
return name;
}
}
//data deserialize
string data = ""; //json string
var obj = JsonSerializer.Deserialize<NearEarthObject>(data, new JsonSerializerOptions
{
PropertyNamingPolicy = new DynamicNamePolicy(),
});

Not able validate data condition based on the json element attribute value from a json using c#

I have a json file, where i have to validate a json attribute element value based on another json element attribute value. But if there json elements with the same name. It always takes the last value always instead of parsing the json data fully. Please guide me.
Below the sample json file
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operation":{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
"Operation":{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
},
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
And below the code which im trying to use
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<plmxmldatamodel>(jsondata);
if (String.Equals(message.PLMXML.traverseRootRefs.Substring(1), message.PLMXML.OperationRevision.id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.PLMXML.OperationRevision.masterRef.Substring(1), message.PLMXML.Operation.id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
public class Operation
{
public string id { get; set; }
public string subType { get; set; }
public string catalogueId { get; set; }
}
public class OperationRevision
{
public string id { get; set; }
public string subType { get; set; }
public string masterRef { get; set; }
}
public class PLMXML
{
public string language { get; set; }
public string author { get; set; }
public string date { get; set; }
public string traverseRootRefs { get; set; }
public Operation Operation { get; set; }
public OperationRevision OperationRevision { get; set; }
}
public class plmxmldatamodel
{
public PLMXML PLMXML { get; set; }
}
When i try to dedug this in the second if condtion, the value for message.PLMXML.Operation.id is always id28 , because of which second if condition fails. While the first if condition is passed as there is only one message.PLMXML.OperationRevision.id. i wanted behaviour where it would check complete json data and check if message.PLMXML.Operation.id with value id21 is present or not , So my data gets passed. Please kindly guide me here.I am very new to C# here.

From my observation you have couple of issues.
What happen you have double keys, and your parser taking the last value not the first one.
First of all your json should be corrected. I assume you have access to change your json and operation should be an array like follow:
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operations":[
{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
}
],
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
When array in place than use an online tool like to validate your json and use this tool to create a model.
Your model will be like this:
public partial class PlmxmlDataModel
{
[JsonProperty("PLMXML")]
public Plmxml Plmxml { get; set; }
}
public partial class Plmxml
{
[JsonProperty("language")]
public string Language { get; set; }
[JsonProperty("author")]
public string Author { get; set; }
[JsonProperty("date")]
public DateTimeOffset Date { get; set; }
[JsonProperty("traverseRootRefs")]
public string TraverseRootRefs { get; set; }
[JsonProperty("Operations")]
public Operation[] Operations { get; set; }
[JsonProperty("OperationRevision")]
public OperationRevision OperationRevision { get; set; }
}
public partial class OperationRevision
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("masterRef")]
public string MasterRef { get; set; }
[JsonProperty("revision")]
public string Revision { get; set; }
}
public partial class Operation
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("catalogueId")]
public string CatalogueId { get; set; }
}
And your method like this:
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<PlmxmlDataModel>(jsondata);
if (String.Equals(message.Plmxml.TraverseRootRefs.Substring(1), message.Plmxml.OperationRevision.Id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.Plmxml.OperationRevision.MasterRef.Substring(1), message.Plmxml.Operations[0].Id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
Now in your method I am looking for array index 0 with contain id 28, but if you are look for id 28 in any of the array then you can do some thing like:
if (message.Plmxml.Operations.Any(e => e.Id == message.Plmxml.OperationRevision.MasterRef.Substring(1)))

JSON invalid format

I'm trying to deserialize the JSON from the weather API, I have created C# classes but I can't seem to get it working. Most sites display this JSON as invalid format, so I'm not really sure whats wrong with it. Here is the JSON string and my class for Deserializing.Visual studio displays it like any other regular JSON.

Your JSON is not valid.
The main thing is that you are using brackets [] where you should be using braces {}.
In JSON [] is an array, while {} is an object. There are a couple of places where you need to have an array (e.g. list) so you can't simply do a find-replace to fix this.
An easy way to resolve this in the future is to create an instance of your WeatherInfo class, populate it with data, and then serialize it to JSON. You can then compare that with the JSON you have (using a diff tool like KDiff or WinMerge) to identify where your source JSON is different from your generated JSON.

A valid JSON always starts with a [ or a { and ends with the same, where square bracket [ represents an array and curly bracket { represents an object.
Looking at your C# class, your JSON lacks the curly brace to start with for objects and is also missing names for the arrays like allinfos.
You should start building your JSON like this:
var json = JToken.Parse
("{\"cod\":\"200\",\"message\":0,\"cnt\":40,\"list\":{\"allinfos\":[{\"dt\":1574175600, \"main\":{\"temp\":284.79,\"temp_min\":282.63,\"temp_max\":284.79,\"pressure\":1021,\"sea_level\":1021,\"grnd_level\":958,\"humidity\":88,\"temp_kf\":2.16}}]}}").ToString(Formatting.Indented);
This will give a formatted, easy to read output like this:
{
"cod": "200",
"message": 0,
"cnt": 40,
"list": {
"allinfos": [
{
"dt": 1574175600,
"main": {
"temp": 284.79,
"temp_min": 282.63,
"temp_max": 284.79,
"pressure": 1021,
"sea_level": 1021,
"grnd_level": 958,
"humidity": 88,
"temp_kf": 2.16
}
}
]
}
}

Update: The JSON was actually valid, the problem is that I was trying to work with debugging version of the string. The debugger automatically adds escape characters and "" quotes. Also some of the classes I had didn't follow up the JSON format correctly, so that error stopped me from seeing the real issue here.

nested json deserialization - need another set of eyes

I have been trying to get this json to deserialize for two days now using RestSharp. I have gone through the RestSharp github site, looked at countless examples, and spent much time here on Stack Overflow to try and find the answer to no avail. My code had previously worked perfectly but the vendor changed their API version and I was forced to do an update to keep using the application for my legal practice. My json is as follows(client info has been removed and replaced with generic info):
{
"data":[
{
"id":1035117666,
"client":
{
"id":905422394,
"name":"client1"
},
"display_number":"11-00012",
"description":"General",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2011-12-14",
"close_date":null,
"billing_method":"hourly"
},
{
"id":1035117768,
"client":
{
"id":905422506,
"name":"client2"
},
"display_number":"12-00037",
"description":"HOA",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2012-08-07",
"close_date":null,
"billing_method":"hourly"
}
],
"meta":
{
"paging":
{
"next":"https://app.goclio.com/api/v4/matters.json?fields=id%2C+client%7Bid%2C+name%7D%2C+display_number%2C+description%2C+practice_area%7Bid%2C+name%7D%2C+status%2C+open_date%2C+close_date%2C+billing_method&limit=2&page_token=BAh7BjoLb2Zmc2V0aQc%3D--b1ea3eba20c8acefbcdfc7868debd1e0ee630c64&status=Open"
},
"records":91
}
}
I built the following schema within my c# code:
public class MatterList
{
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
public class Meta
{
public Paging paging { get; set; }
public int records { get; set; }
}
public class Paging
{
public string previous { get; set; }
public string next { get; set; }
}
[DeserializeAs(Name = "data")]
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
public class PracticeArea
{
public int id { get; set; }
public string name { get; set; }
}
public class Client
{
public int id { get; set; }
public string name { get; set; }
}
When I run the RestSharp deserialize method I am sending the result to an object of type MatterList using the following line of code
MatterList matterList = jsonHandler.Deserialize<MatterList>(response);
I have so far attempted to deserialize without the Meta or Paging POCO classes with the accompanying change to the MatterList class (taking out the Meta property).
I have tried with and without the [DeserializeAs(Name="data")] directive.
I have tried to set the RootElement of the json response prior to deserialization.
I have tried to shorthand the deserialization by combining it with the Execute request code
IRestResponse<MatterList> matterList = client.Execute<MatterList>(request);
I have created a container class called MatterContainer which I placed between MatterList and Matter classes in the schema:
public class MatterList
{
public List<MatterContainer> matters { get; set; }
}
public class MatterContainer
{
public Matter matter { get; set; }
}
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
I know I am getting the json response back from the server correctly so my request is proper and MatterList is not null after deserialization. The problem is that I cannot get the deserialization to actually populate the List matters within the MatterList class.
I have been looking at this off and on for two days and cannot get past this hurdle. If anyone sees what I did wrong I would greatly appreciate the insight, I am at a point where I cannot progress further with my application.
Thanks!

I think your [DeserializeAs(Name = "data")] attribute is in the wrong place. Try putting it in the root class instead:
public class MatterList
{
[DeserializeAs(Name = "data")]
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
alternatively, try renameing that property to data

Json String doesn't deserialize

I have the following JSON:
{"success":1,
"return":{
"funds": {
"usd":0,
"btc":0,
"ltc":0
},
"rights": {
"info":1,
"trade":0,
"withdraw":0
},
"transaction_count":1,
"open_orders":0,
"server_time":1406470221
}
}
I'm trying to deserialize it with:
JsonConvert.DeserializeObject<UserInfo>(jsonString);
Classes are as follows:
public class UserInfo
{
[JsonProperty("transaction_count")]
public int TransactionCount { get; set; }
[JsonProperty("open_orders")]
public int OpenOrders { get; set; }
[JsonProperty("server_time")]
public int ServerTime { get; set; }
[JsonProperty("funds")]
public Funds Funds { get; set; }
[JsonProperty("rights")]
public Rights Rights { get; set; }
}
public class Funds
{
[JsonProperty("btc")]
public decimal Btc { get; set; }
[JsonProperty("ltc")]
public decimal Ltc { get; set; }
[JsonProperty("usd")]
public decimal Usd { get; set; }
};
public class Rights
{
[JsonProperty("info")]
public bool Info { get; set; }
[JsonProperty("trade")]
public bool Trade { get; set; }
[JsonProperty("withdraw")]
public bool Withdraw { get; set; }
}
I tried not using the attributes and other tutorials, but nothing seems to work.. =(
Why doesn't it work? I don't know how to set return as a root, for example. Is it possible?
Thank you.

Try this:
public class Funds
{
public int usd { get; set; }
public int btc { get; set; }
public int ltc { get; set; }
}
public class Rights
{
public int info { get; set; }
public int trade { get; set; }
public int withdraw { get; set; }
}
public class Return
{
public Funds funds { get; set; }
public Rights rights { get; set; }
public int transaction_count { get; set; }
public int open_orders { get; set; }
public int server_time { get; set; }
}
public class RootObject
{
public int success { get; set; }
public Return #return { get; set; }
}
And to deserialize:
JsonConvert.DeserializeObject<RootObject>(jsonString);
Reference: http://json2csharp.com/

Your JSON isn't well-formed.
{"success":1,
"return":{
"funds": <-- missing {
"usd":0,
"btc":0,
"ltc":0
},
"rights": <-- missing {
"info":1,
"trade":0,
"withdraw":0
},
"transaction_count":1,
"open_orders":0,
"server_time":1406470221
}
}
Regarding your question about setting root, try writing a simple wrapper class to represent your actual JSON hierarchy, then deserialize the whole string as is, it will work if your object graph maps to the JSON.
EDIT:See #Crasher's answer, it is exactly what I mean, with an actual sample (though I didnt verify, I will upvote it), though #dcastro's answer is the cleanest.
An alternative to dcastro's exact example, if you use JObject to handle the dynamic root, you can also use JObject.First to either avoid naming the root, or allow root to change. Please upvote his answer, I'm just providing a dynamic alternative.
var root = JObject.Parse(jsonStr).First;

You don't need to create a wrapper/root class just for this, as others answers suggest.
You can parse the whole thing into a JObject, and then convert just the return node into a UserInfo object.
JObject obj = JObject.Parse(jsonStr);
var userInfo = obj["return"].ToObject<UserInfo>();
