I have these classes
public class ResponseEntryInfoAndTollDue
{
public int Code { get; set; }
public string Message { get; set; }
public TagEntryInfo TagEntryInfo { get; set; }
public TollMatrix TollMatrix { get; set; }
public List<TagInfoParam> TagInfoParams { get; set; }
public ResponseEntryInfoAndTollDue()
{
TagEntryInfo = new TagEntryInfo();
TollMatrix = new TollMatrix();
TagInfoParams = new List<TagInfoParam>();
}
}
public class TagEntryInfo
{
public long TrxnID { get; set; }
public string TagRFIDNumber { get; set; }
public string EntryTrxnDTime { get; set; }
public int EntryPlaza { get; set; }
public short EntryLane { get; set; }
public string EntryDirection { get; set; }
public string EntryLaneType { get; set; }
public string PostingDateTime { get; set; }
public string Action { get; set; }
}
public class TollMatrix
{
public decimal TollDue { get; set; }
public decimal TollVat { get; set; }
public decimal TollNoVat { get; set; }
public bool IsDefaulted { get; set; }
}
public class TagInfoParam
{
public DateTime? AsOfDate { get; set; }
public Decimal? AvailableBalance { get; set; }
public string TagNumber { get; set; }
public string PLateNumber { get; set; }
public Int16 HonorPlate { get; set; }
public Int16 TagStatusID { get; set; }
public string TID { get; set; }
public string EPC { get; set; }
public string AccountTypeID { get; set; }
public Int16 AccountStatusID { get; set; }
public Int16 TagClassID { get; set; }
public Int16 Status { get; set; }
}
From a webservice I get this json string:
{"Result":{"Code":0,"Message":"With entry info computed toll due","TagEntryInfo":{"TrxnID":6666750,"TagRFIDNumber":"1234567890","EntryTrxnDTime":"2021-01-16 16:40:16.560","EntryPlaza":123,"EntryLane":1,"EntryDirection":"B","EntryLaneType":"A","PostingDateTime":"2021-01-16T16:43:16.05","Action":"A"},"TollMatrix":{"TollDue":164.0000,"TollVat":17.5700,"TollNoVat":146.4300,"IsDefaulted":false},"TagInfoParams":[{"AsOfDate":"2021-01-16T17:12:04.213","AvailableBalance":537.0000,"TagNumber":"1234567890","PLateNumber":"Q123","HonorPlate":1,"TagStatusID":1,"TID":"Elfkajs98","EPC":"889080990709","AccountTypeID":"REV","AccountStatusID":1,"TagClassID":1,"Status":1}]},"Id":351,"Exception":null,"Status":5,"IsCanceled":false,"IsCompleted":true,"CreationOptions":0,"AsyncState":null,"IsFaulted":false}
This is how I convert it:
var response = JsonConvert.DeserializeObject(ret);
I know that it doesn't get converted because this is what I get:
This is the result:
Why is this not being converted into an object?
As Fabio also mentioned that your json contains the attribute Result which is not part of your object so you can use below logic to deserialize
var jObj = JObject.Parse(json);
var responseEntryInfoAndTollDue = JsonConvert.DeserializeObject<ResponseEntryInfoAndTollDue>(jObj["Result"].ToString());
The above code first parse the Json to JObject and uses Result property to deserialize to ResponseEntryInfoAndTollDue object.

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 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);
I am working with processing/consuming some data from: https://ashesescalation-api-tachyon.stardock.net/v1/products/2641/leaderboards/ladder/de5bfc9a-9092-4014-b52e-89151de42646?offset=0&count=2 (which can be opened easily in Firefox to view.)
I am able to access the data in C# by doing this:
data being the json data...
dynamic players = JArray.Parse(data);
var p = players[0];
Console.Write(p.personaName);
However I am having trouble accessing the part in the JSON data: "dataInteger" for example the "totalUnitsKilled."
p.dataInteger[0].totalUnitsKilled
That "p.dataInteger[0].totalUnitsKilled" doesn't work.
How can I access that data in C#?
Thank you very much for your help.

Kinldy take a look at my comment in your question, base on that link you need to use JsonProperty to mapped the key that has special characters and manually named it based on your needs.
Anyways, you can do the following to achieved what you need.
Copy your link to http://json2csharp.com/
Copy the generated Quicktypes and paste it to your code.
Use JsonProperty to indicate attributes on your properties for the names and manually rename properties that contains invalid_name
And DeserializeObject the object.
Here is the code:
Declare the classes from the generated quicktypes.
public class DataInteger
{
[JsonProperty(PropertyName = "totalUnitsKilled ")]
public int totalUnitsKilled { get; set; }
public int totalTitansKilled { get; set; }
public int totalTimePlayed { get; set; }
[JsonProperty(PropertyName = "substrate-TotalGamesPlayed")]
public int SubstrateTotalGamesPlayed { get; set; }
[JsonProperty(PropertyName = "phC-TotalGamesPlayed")]
public int PHCTotalGamesPlayed { get; set; }
public int lastReplayVersion { get; set; }
public int replayUploadedCount { get; set; }
}
public class RootObject
{
public string personaLadderId { get; set; }
public int rank { get; set; }
public string personaId { get; set; }
public string personaName { get; set; }
public string avatarUrl { get; set; }
public string avatarUrlSmall { get; set; }
public string avatarUrlMedium { get; set; }
public string avatarUrlLarge { get; set; }
public string ladderType { get; set; }
public string ladderId { get; set; }
public string seasonId { get; set; }
public int bracketId { get; set; }
public string bracketName { get; set; }
public int rankingScore { get; set; }
public int secondaryScore { get; set; }
public int ruleTypeId { get; set; }
public int wins { get; set; }
public int losses { get; set; }
public int ties { get; set; }
public int tieStreak { get; set; }
public int winStreak { get; set; }
public int lossStreak { get; set; }
public int longestTieStreak { get; set; }
public int longestWinStreak { get; set; }
public int longestLossStreak { get; set; }
public int bracketMaxScore { get; set; }
public int bracketScore { get; set; }
public DateTime updateDate { get; set; }
public int totalMatchesPlayed { get; set; }
public DataInteger dataInteger { get; set; }
}
Call the API (Magic begins here)
var httpClient = new HttpClient();
var link = $#"https://ashesescalation-api-tachyon.stardock.net/v1/products/2641/leaderboards/ladder/de5bfc9a-9092-4014-b52e-89151de42646?offset=0&count=2";
var response = await httpClient.GetAsync(link);
var contents = await response.Content.ReadAsStringAsync();
//deserialized json result object...
dynamic json = JsonConvert.DeserializeObject(contents);
foreach (var item in json)
{
//deserialized again the item
var data = JsonConvert.DeserializeObject<RootObject>(Convert.ToString(item));
//you can now access all the properties including dataInteger.
Console.WriteLine(Convert.ToString(data.dataInteger.totalUnitsKilled));
Console.WriteLine(Convert.ToString(data.dataInteger.totalTitansKilled));
}
Update:
If you don't want to use strongly typed class you can do parsing using JArray
JArray jsonVal = JArray.Parse(contents) as JArray;
dynamic items = jsonVal;
foreach (dynamic item in items)
{
var x = item.dataInteger;
//you can access the fields inside dataInteger.
Console.WriteLine(x["totalUnitsKilled "]);
Console.WriteLine(x["phC-TotalGamesPlayed"]);
Console.WriteLine(x["substrate-TotalGamesPlayed"]);
}
Hope this will help you.
As suggested by other users, there is a space in property name "totalUnitsKilled ", if you change it to "totalUnitsKilled". Below code will work fine:-
Console.WriteLine(p.dataInteger.totalUnitsKilled);
Your JSON string is wrong.

There is a space in your json key name ("totalUnitsKilled ") which is ultimately converted to a variable name.
Correct your JSON key name will fix this issue. There are other keys with error as well.
You can check at http://json2csharp.com/. Wherever it is "invalid_name", key name is wrong.
public class DataInteger
{
public int __invalid_name__totalUnitsKilled { get; set; }
public int totalTitansKilled { get; set; }
public int totalTimePlayed { get; set; }
public int __invalid_name__substrate-TotalGamesPlayed { get; set; }
public int __invalid_name__phC-TotalGamesPlayed { get; set; }
public int lastReplayVersion { get; set; }
public int replayUploadedCount { get; set; }
}

public int rank { get; set; }
public string personaId { get; set; }
public string personaName { get; set; }
public string avatarUrl { get; set; }
public string avatarUrlSmall { get; set; }
public string avatarUrlMedium { get; set; }
public string avatarUrlLarge { get; set; }
public string ladderType { get; set; }
public string ladderId { get; set; }
public string seasonId { get; set; }
public int bracketId { get; set; }
public string bracketName { get; set; }
public int rankingScore { get; set; }
public int secondaryScore { get; set; }
public int ruleTypeId { get; set; }
public int wins { get; set; }
public int losses { get; set; }
public int ties { get; set; }
public int tieStreak { get; set; }

public int totalMatchesPlayed { get; set; }
public DataInteger dataInteger { get; set; }
}
You can use JSON.Net attributes to define C# variables related to JSON key names. Check this for more details.
Your new class should look like:
public class DataInteger
{
[JsonProperty(PropertyName = "totalUnitsKilled ")]
public int totalUnitsKilled { get; set; }
public int totalTitansKilled { get; set; }
public int totalTimePlayed { get; set; }
[JsonProperty(PropertyName = "substrate-TotalGamesPlayed")]
public int substrateTotalGamesPlayed { get; set; }
[JsonProperty(PropertyName = "phC-TotalGamesPlayed")]
public int phCTotalGamesPlayed { get; set; }
public int lastReplayVersion { get; set; }
public int replayUploadedCount { get; set; }
}

I use this code. I know it has many errors but I need someone guide me.
private void Button_Click(object sender, RoutedEventArgs e)

var uri = new Uri(uriString);
var httpWebRequest = HttpWebRequest.Create(uri);

var outerRoot = JsonConvert.DeserializeObject<OuterRootObject>( json );
var root = JsonConvert.DeserializeObject<RootObject>( outerRoot.d );
MessageBox.Show(root.UserId);
}
This is kind of a nasty situation. What you're getting back is a JSON object with a single property (i.e. d) and that property contains a string of JSON. So you basically need to unwrap the inner JSON from it's envelope. The following classes/code should work (using JSON.NET to do the deserialization).

public string d { get; set; }

var outerRoot = JsonConvert.DeserializeObject<OuterRootObject>( json );
var root = JsonConvert.DeserializeObject<RootObject>( outerRoot.d );
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.
