Accessing Nested Collection View JSON data

Accessing Nested Collection View JSON data - c#

I have a nested JSON data to be accessed. The data is structured into nested data which i want to have into one.
I modeled the JSON response into c# model classes
public class Customer1
{
public string district { get; set; }
public string feeder { get; set; }
public string feeder_code { get; set; }
public string transformer { get; set; }
public string dss_code { get; set; }
public string database_match { get; set; }
public string accountnumber { get; set; }
public string meterno { get; set; }
public TransactionalDetails transactional_details { get; set; }
}
public class Customer2
{
public string accountNumber { get; set; }
public string meterNumber { get; set; }
public string phoneNumber { get; set; }
public int billedAmount { get; set; }
public object billedDate { get; set; }
public string lastPayDate { get; set; }
public Lastpayment lastpayment { get; set; }
}
public class Lastpayment
{
public string transactionRef { get; set; }
public int units { get; set; }
public string transactionDate { get; set; }
public string transactionId { get; set; }
public int transactionBookId { get; set; }
public int amountPaid { get; set; }
public int mscPaid { get; set; }
public string invoiceNumber { get; set; }
}
public class Queryresult
{
public string responseMessage { get; set; }
public Customer1 customer1 { get; set; }
public int responseCode { get; set; }
public string status { get; set; }
}
public class Result
{
public ObservableCollection<Customer1> Customer1 { get; set; }
public int row_count { get; set; }
}
public class Root
{
public bool error { get; set; }
public Result result { get; set; }
}
public class TransactionalDetails
{
public Queryresult queryresult { get; set; }
public bool status { get; set; }
}
I also created the following code to access the data using the root.
var data = JsonConvert.DeserializeObject<root>(readTask);
ObservableCollection<Customer1> innerData2 = data.result.Customer1;
My challenge is that i want to have Customer1, Customer2 and last payment data merged into a single collection view.
with what i have done, i can only access customer1 data. how can i access all into a single collection?

Crestron Deserialize in C# and send array to Simpl+

Trying best how to take the following classes and deserialize a Json file to return each class values back to Simpl+. I am able to receive the Total value but anything in a list I am at a lost.
public class Client
{
public string clientId { get; set; }
public string locale { get; set; }
public string location { get; set; }
public string auxiliaryId { get; set; }
public string description { get; set; }
public string type { get; set; }
public string typeDescription { get; set; }
public Hardware hardware { get; set; }
public Network network { get; set; }
}
public class Hardware
{
public string type { get; set; }
public string softwareVersion { get; set; }
public string serialNumber { get; set; }
public string hardwareVersion { get; set; }
public string model { get; set; }
}
public class Network
{
public string ip { get; set; }
public string mac { get; set; }
public object homepage { get; set; }
public string dhcpSubnet { get; set; }
}
public class Result
{
public List<Client> clients { get; set; }
public string total { get; set; }
public int limit { get; set; }
public int page { get; set; }
}
public class Root
{
public string jsonrpc { get; set; }
public object id { get; set; }
public Result result { get; set; }
}

I was able to resolve this by adding the following to the foreach statement:
args.MyIndex = (ushort)(rootObject.TriplePlayResult.clients.IndexOf(item) + 1);

Deserializing the JSON Objest results in all null fields C#

My jsonResponse is something like this:
{"status":200,"data":{"first_name":"\u062e\u0633","last_name":"\u0635\u062f\u0627","national_code":"1","image_photo":"1.jpg","cellphone":"1234","city":{"id":1,"name":"x","created_at":"2017-02-27 17:54:44","updated_at":"2017-02-27 17:54:44"},"email":"something#gmail.com","even_odd":1,"Register Time":"2018-01-25 10:39:17","is_blocked":false,"receive_regular_offer":"false","level":1,"ride_count":0,"service_type":1,"bank":"\u0645","iban":"xy","card_number":"","holder":"\u062e\u0633","plate_number":"123","vehicle_model":"\u067e\u0698","vehicle_color":"\u062a\u0627\u06a9\u0633","unique_id":592875}}
I have created a class like this:
public class Driver
{
public string first_name { get; set; }
public string last_name { get; set; }
public string national_code { get; set; }
public string image_photo { get; set; }
public string cellphone { get; set; }
public string city { get; set; }
public string email { get; set; }
public string even_odd { get; set; }
public bool is_blocked { get; set; }
public bool receive_regular_offer { get; set; }
public string level { get; set; }
public string ride_count { get; set; }
public string service_type { get; set; }
public string bank { get; set; }
public string iban { get; set; }
public string card_number { get; set; }
public string holder { get; set; }
public string vehicle_model { get; set; }
public string vehicle_color { get; set; }
public string unique_id { get; set; }
}
and used this:
jsonResponse = reader.ReadToEnd();
JavaScriptSerializer js = new JavaScriptSerializer();
Driver snappDriver = js.Deserialize<Driver>(jsonResponse);
But the result is all null!

1.your class should be defined right
example:
void Main()
{
var json =api();
//dynamic
var dynamic_json = JsonConvert.DeserializeObject(json).Dump() as JObject;
//strong type
var strong_Type_json = JsonConvert.DeserializeObject<Driver>(json).Dump() ;
}
string api(){
return #"
{""status"":200,""data"":{""first_name"":""\u062e\u0633"",""last_name"":""\u0635\u062f\u0627"",""national_code"":""1"",""image_photo"":""1.jpg"",""cellphone"":""1234"",""city"":{""id"":1,""name"":""x"",""created_at"":""2017-02-27 17:54:44"",""updated_at"":""2017-02-27 17:54:44""},""email"":""something#gmail.com"",""even_odd"":1,""Register_Time"":""2018-01-25 10:39:17"",""is_blocked"":false,""receive_regular_offer"":""false"",""level"":1,""ride_count"":0,""service_type"":1,""bank"":""\u0645"",""iban"":""xy"",""card_number"":"""",""holder"":""\u062e\u0633"",""plate_number"":""123"",""vehicle_model"":""\u067e\u0698"",""vehicle_color"":""\u062a\u0627\u06a9\u0633"",""unique_id"":592875}}
";
}
public class City
{
public int id { get; set; }
public string name { get; set; }
public string created_at { get; set; }
public string updated_at { get; set; }
}
public class Data
{
public string first_name { get; set; }
public string last_name { get; set; }
public string national_code { get; set; }
public string image_photo { get; set; }
public string cellphone { get; set; }
public City city { get; set; }
public string email { get; set; }
public int even_odd { get; set; }
public string Register_Time { get; set; }
public bool is_blocked { get; set; }
public string receive_regular_offer { get; set; }
public int level { get; set; }
public int ride_count { get; set; }
public int service_type { get; set; }
public string bank { get; set; }
public string iban { get; set; }
public string card_number { get; set; }
public string holder { get; set; }
public string plate_number { get; set; }
public string vehicle_model { get; set; }
public string vehicle_color { get; set; }
public int unique_id { get; set; }
}
public class Driver
{
public int status { get; set; }
public Data data { get; set; }
}
2.json's key Register Time in strong type is invalid name
you can add _ in your json string to solve the problem

Try to create exactly the same class definition as your json has. Your Driver class describes json object's data property.
public class DriverWrapper
{
public string status { get; set; }
public Driver data { get; set; }
}

You have to create another object class that handles status and data property
try this
Create a class Response
class Response{
public int status { get; set;}
public Driver data { get; set;}
}
and do it this way
jsonResponse = reader.ReadToEnd();
JavaScriptSerializer js = new JavaScriptSerializer();
Response snappDriver = js.Deserialize<Response>(jsonResponse);

Error with deserializing complex Json

I deserialize complex JSON (Spotify Playlist) and get root level values but I cannot get branches values. I Google problem, try different options without success but, I assume its silly mistake or lack of knowledge so therefore just ask for help what I am missing?
My classes are:
public class Playlist
{
public string collaborative { get; set; }
public string description { get; set; }
//public <ExternalUrls> external_urls { get; set; } //object
//public List<Followers> followers { get; set; } //object
public string href { get; set; }
public string id { get; set; }
//public List<Image> images { get; set; } //array
public string name { get; set; }
}
public class Tracks
{
public string href { get; set; }
public Item items { get; set; } //object
public string limit { get; set; }
public string next { get; set; }
public string offset { get; set; }
public string previous { get; set; }
public string total { get; set; }
}
And code to deserialize looks like that:
StreamReader responseFromServer = new StreamReader(myWebResponse.GetResponseStream());
var dataResponse = responseFromServer.ReadToEnd();
responseFromServer.Close();
var elements = new JavaScriptSerializer().Deserialize<Playlist>(dataResponse);
RootBuffer.AddRow();
RootBuffer.collaborative = elements.collaborative.ToString();
foreach (Tracks trs in elements.tracks)
{
TracksBuffer.AddRow();
TracksBuffer.href = trs.href.ToString()
}

I genereated the classes using this excellent site: json2csharp.com
And used your existing deserialization code successfully with the following classes. It populated all the data including the child collections (brace yourself, it's a long one):
public class Playlist
{
public bool collaborative { get; set; }

public int limit { get; set; }
public object next { get; set; }
public int offset { get; set; }
public object previous { get; set; }
public int total { get; set; }
}
Hope this helps.

Null value in json object

I made a code for deserialize this JSON
First of all, I've created a class:
public class Self
{
public string href { get; set; }
}
public class Soccerseason
{
public string href { get; set; }
}
public class HomeTeam
{
public string href { get; set; }
}
public class AwayTeam
{
public string href { get; set; }
}
public class Links
{
public Self self { get; set; }
public Soccerseason soccerseason { get; set; }
public HomeTeam homeTeam { get; set; }
public AwayTeam awayTeam { get; set; }
}
public class Result
{
public int goalsHomeTeam { get; set; }
public int goalsAwayTeam { get; set; }
}
public class LastHomeWinHomeTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastWinHomeTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastAwayWinAwayTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastWinAwayTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class Head2head
{
public int count { get; set; }
public string timeFrameStart { get; set; }
public string timeFrameEnd { get; set; }
public int homeTeamWins { get; set; }
public int awayTeamWins { get; set; }
public int draws { get; set; }
public LastHomeWinHomeTeam lastHomeWinHomeTeam { get; set; }
public LastWinHomeTeam lastWinHomeTeam { get; set; }
public LastAwayWinAwayTeam lastAwayWinAwayTeam { get; set; }
public LastWinAwayTeam lastWinAwayTeam { get; set; }
public List<Fixture> fixtures { get; set; }
}
public class Fixture
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class RootObject
{
public List<Fixture> fixture { get; set; }
public Head2head head2head { get; set; }
}
So I made a code for parsing a request, and return a responseText:
string responseText = Parser.Request(link); //Parser is the class that perform HttpRequest
so far no problem.
I've declarated the object for deserialize the responseText returned:
var obj = JsonConvert.DeserializeObject<Fixtures.RootObject>(responseText);
and next I do the foreach:
foreach (var fixture in obj.fixture)
{do stuff..}
but in obj.fixture I get null and I don't know why. Because all JSON is deserialized correcly. What am I doing wrong?

The key in the JSON is "fixtures" - it needs to match the property name of your class exactly. Change
public List<Fixture> fixture { get; set; }
to
public List<Fixture> fixtures { get; set; }
Alternatively, you can use the JsonProperty attribute:
[JsonProperty("fixtures")]
public List<Fixture> fixture { get; set; }

Could not cast or convert from {null} to system.Int32 in JSON response C#

I'm getting the following exception when using this bit of code to deserialize a JSON response from CrunchBase. The weird thing is it only happens to certain pages that are being deserialized even though both the results that work fine and the ones that don't both have empty [], empty"", and null values in key:value pairs. How can I cast or correct my mistake?
Exception gets thrown here:
JsonSerializer serializer = new JsonSerializer();
RootObject ro = JsonConvert.DeserializeObject<RootObject>(response);
The inner exception is:
InnerException:
Message=Could not cast or convert from {null} to System.Int32.
Source=Newtonsoft.Json
Thanks for your eyes in advance!
Update:
as asked for the structure of the root object and the additional objects on that JSON endpoint. These were generated by http://json2csharp.com/ after putting the URL of the JSON endpoint into it.
The JSON is long so here are two example links: this one works without error http://api.crunchbase.com/v/1/company/kiip.js , while this other (and others) throws the exception http://api.crunchbase.com/v/1/company/tata-communications.js

Json.NET supports JSON Schema. You could create a schema with all the required properties marked and validate incoming JSON against it before deserializing. In this you can check if value is null you can make change it to some default value.
Hope this works for you.
