Develop Reference

Change values in a JSON file C#

I have this code. How do I change the values of the JSON objects in code.
"externalReference": "Integrator Reference",
"proposalType": "Private Individual",
"dealer": {
"dealerID": 9344
},
"financeDetails": {
"type": "HP",
"cashDeposit": 111,
"settlement": 11,
"partExchange": 22,
"term": 72,
"apr": 12.9,
"loanamount": 0.0,
"distanceSelling": true,
"vehicleAsset": {
"type": "Used",
"class": "Car",
"source": "UK",
"purpose": "Social",
"vrm": "string",
"dateOfRegistration": "16-10-2020",
"manufacturer": "string",
"model": "string",
"derivative": "string",
"capCode": "ALGU21S164SDTA",
"CurrentMileage": 25000,
"vatRate": 20,
"netValue": 5000
},
"additionalAssets": [
{
"type": "MOT",
"netValue": 250,
"vatRate": 20,
"description": "string"
},
{
"type": "BCI_VAT",
"netValue": 350,
"vatRate": 5,
"description": "string"
}
]
},
I have this so far;
public static void CallRequest(string fieldName, string enteredFieldValue)
{
string sendProposalRequestSuccess = File.ReadAllText(sendProposalUnityJSONFile);
dynamic jsonObj = JsonConvert.DeserializeObject(sendProposalRequestSuccess);
jsonObj[fieldName] = enteredFieldValue;
string output = JsonConvert.SerializeObject(jsonObj, Formatting.Indented);
File.WriteAllText(sendProposalUnityJSONFile, output);
}

You can use JObject which has a method to parse json text you read from file to json objects. You can then access property using keys depending on the depth of the property.
1) JObject Parsing and Modification
string sendProposalRequestSuccess = File.ReadAllText("myjson.json");
JObject jsonObj = JObject.Parse(sendProposalRequestSuccess);
jsonObj["proposalType"] = "Private Company";
jsonObj["financeDetails"]["cashDeposit"] = 213;
string output = JsonConvert.SerializeObject(jsonObj, Formatting.Indented);
File.WriteAllText("myjson2.json", output);
Demo Example:
https://dotnetfiddle.net/DZA5BI
2) Json to C# Classes:
Another approach is convert json to C# classes using this helpful online tool. You can then deserialize json object to main class MyJson. This way you can access each property field and modify at your will then save json back to file.
This is pretty useful if you want to save to database or show in a table and several other applications.
public class MyJson
{
public string externalReference { get; set; }
public string proposalType { get; set; }
public Dealer dealer { get; set; }
public FinanceDetails financeDetails { get; set; }
}
public class AdditionalAsset
{
public string type { get; set; }
public int netValue { get; set; }
public int vatRate { get; set; }
public string description { get; set; }
}
public class Dealer
{
public int dealerID { get; set; }
}
public class FinanceDetails
{
public string type { get; set; }
public int cashDeposit { get; set; }
public int settlement { get; set; }
public int partExchange { get; set; }
public int term { get; set; }
public double apr { get; set; }
public double loanamount { get; set; }
public bool distanceSelling { get; set; }
public VehicleAsset vehicleAsset { get; set; }
public List<AdditionalAsset> additionalAssets { get; set; }
}
public class VehicleAsset
{
public string type { get; set; }
public string #class { get; set; }
public string source { get; set; }
public string purpose { get; set; }
public string vrm { get; set; }
public string dateOfRegistration { get; set; }
public string manufacturer { get; set; }
public string model { get; set; }
public string derivative { get; set; }
public string capCode { get; set; }
public int CurrentMileage { get; set; }
public int vatRate { get; set; }
public int netValue { get; set; }
}
Implementation:
string sendProposalRequestSuccess = File.ReadAllText("myjson.json");
var jsonObj = JsonConvert.DeserializeObject<MyJson>(sendProposalRequestSuccess);
jsonObj.financeDetails.cashDeposit = 231;
string output = JsonConvert.SerializeObject(jsonObj, Formatting.Indented);
File.WriteAllText("myjson2.json", output);
Output:

Deserilizing Json Response of HttpClient using ASP.NET Core

I am calling a third-party API with HttpClient GET Request and it works fine. The response is quite complex of objects. All I want to do is to extract a specific attribute within these objects. Here is the response Json
"creationTime": "2021-11-06T12:22:49.602Z",

"timeOfRecord": "2021-11-06T12:22:49.617Z",
}
]
}
I'd like to extract "status": "CAPTURED" and "acquirerCode": "00" . here is what I tried
var client = new HttpClient();
string _ContentType = "application/json";
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(_ContentType));
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", base64EncodedAuthenticationString);
var _UserAgent = "d-fens HttpClient";
client.DefaultRequestHeaders.Add("User-Agent", _UserAgent);
HttpResponseMessage response;
response = await client.GetAsync(api_URL);
var resContent = JsonConvert.DeserializeObject(await response.Content.ReadAsStringAsync());
var content = response.Content.ReadAsStringAsync().Result;
return Ok(resContent);
Extracting these values would solve the issue I'm facing. Thanks in advance

if you need just this 2 values the easiest way is
var json = response.Content.ReadAsStringAsync().Result;
var result = JObject.Parse(json);
var status= result["status"];
var acquirerCode= result["transaction"][0]["response"]["acquirerCode"];
output
CAPTURED
00
And there is a hard way
var json = response.Content.ReadAsStringAsync().Result;
var jsonDeserialized=JsonConvert.DeserializeObject<Data>(json);
var status= jsonDeserialized.Status;
var acquirerCode=jsonDeserialized.Transaction.Select(t => t.Response.AcquirerCode).FirstOrDefault();

Newtonsoft.Json.JsonReaderException: 'Unexpected character encountered while parsing value

I have a Json Model Schema from a third party API that looks like this:
{
"Entries": [
{
"Id": "",
"RowId": 0,
"FormId": "",
"FormExternalId": "",
"FormVersion": 0,
"DeviceId": "",
"UserFirstName": "",
"UserLastName": "",
"UserEmail": "",
"UserExternalId": "",
"Latitude": 0,
"Longitude": 0,
"StartTime": "Date",
"CompleteTime": "Date",
"ReceivedTime": "Date",
"AnswerFormat": "",
"Answers": [
{
"Name": "",
"Type": "",
"Value": "",
"Answers": [
"Answer_GET_"
]
}
],
"AnswersFlat": "Array[AnswerSet]",
"AnswersFlatXml": "XML",
"AnswersRawXml": "XML",
"AnswersRawJson": "JSON",
"TaskId": "",
"DSRowId": "",
"MediaAsUrl": false,
"Fields": "",
"PurgeDays": 0,
"CompanyId": 0
}
],
"TotalRows": 0,
"ResponseStatus": {
"ErrorCode": "",
"Message": "",
"Errors": [
{
"ErrorCode": "",
"FieldName": "",
"Message": ""
}
]
}
}
I made a class for this in Visual Studio that looks like this:
class form_results
{
public class Rootobject
{
public Entry[] Entries { get; set; }
public int TotalRows { get; set; }
public Responsestatus ResponseStatus { get; set; }
}
public class Responsestatus
{
public string ErrorCode { get; set; }
public string Message { get; set; }
public Error[] Errors { get; set; }
}
public class Error
{
public string ErrorCode { get; set; }
public string FieldName { get; set; }
public string Message { get; set; }
}
public class Entry
{
public string Id { get; set; }
public int RowId { get; set; }
public string FormId { get; set; }
public string FormExternalId { get; set; }
public int FormVersion { get; set; }
public string DeviceId { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserEmail { get; set; }
public string UserExternalId { get; set; }
public float Latitude { get; set; }
public float Longitude { get; set; }
public string StartTime { get; set; }
public string CompleteTime { get; set; }
public string ReceivedTime { get; set; }
public string AnswerFormat { get; set; }
public Answer[] Answers { get; set; }
public string AnswersFlat { get; set; }
public string AnswersFlatXml { get; set; }
public string AnswersRawXml { get; set; }
public string AnswersRawJson { get; set; }
public string TaskId { get; set; }
public string DSRowId { get; set; }
public bool MediaAsUrl { get; set; }
public string Fields { get; set; }
public int PurgeDays { get; set; }
public int CompanyId { get; set; }
}
public class Answer
{
public string Name { get; set; }
public string Type { get; set; }
public string Value { get; set; }
public string[] Answers { get; set; }
}
}
When I try to deserialize the json with the following command:
var parsedJson = JsonConvert.DeserializeObject<form_results.Rootobject>(json);
I'm geting the error "Newtonsoft.Json.JsonReaderException: 'Unexpected character encountered while parsing value: {. Path 'Entries[0].Answers[0].Answers', line 25, position 25.'"
That part of the Json string looks like this:
{... more json results...
"AnswerFormat": "Rich",
"Answers": [{
"Name": "Page 1",
"Type": "Group",
"Answers": [{
"Name": "Value 1",
"Type": "SelectOne"
},
{
"Name": "Value 2",
"Type": "SelectOne"
}
]
}]
}
]
The Json is valid, so that is not the problem. As far as I can see the problem occurs at the array section of the Json file.
Also tried var parsedJson = JsonConvert.DeserializeObject <List<form_results.Rootobject>>(json); but gave also an error.
What I want is the results (answers) from the Answers array.

Your Answer class is declared like this
public class Answer
{
public string Name { get; set; }
public string Type { get; set; }
public string Value { get; set; }
public string[] Answers { get; set; }
}
This includes an array of string called Answers
But in your JSON, this array is an array of objects (Extract below)
"Answers": [{
"Name": "Value 1",
"Type": "SelectOne"
},
{
"Name": "Value 2",
"Type": "SelectOne"
}
]
So you need to change your class to match this JSON. Maybe like this
public class Answer
{
public string Name { get; set; }
public string Type { get; set; }
public string Value { get; set; }
public SubAnswer[] Answers { get; set; }
}
public class SubAnswer
{
public string Name { get; set; }
public string Type { get; set; }
}
Or you could maybe use the Composite pattern, if you want Answer and SubAnswer to be the same.

It looks like the class answers can contain further answers thats why you can modify your Answer class like following:
public class Answer
{
public string Name { get; set; }
public string Type { get; set; }
public string Value { get; set; }
public List<Answer> Answers { get; set; }
}

JSON deserialization is not working in Web API

I want to deserialize a json request but it is not working in Web API. My code is below for the deserialization. Can you please tell me what I am doing wrong?
[HttpPost]
public HttpResponseMessage AddOrder(string username , string password, JObject jsonResult)
{
try
{
AuthRepository _auth = new AuthRepository();
OrderDTO.RootObject O = new OrderDTO.RootObject();
O = JsonConvert.DeserializeObject<OrderDTO.RootObject>(jsonResult.ToString());
}
catch (Exception ex)
{
return Request.CreateErrorResponse(System.Net.HttpStatusCode.BadRequest, ex);
}
}
This is the JSON that will received by our method:
{
"token": "D8xJD2CI6PrkB3q5gnlT",
"shipment": {
"hawb": "0800780108",
"service_level": "CURBSIDE",
"status": "NEW",
"description": "bundle of things",
"service_level_code": "CB",
"delivery_date": "8/22/2019 5:01:00 PM",
"delivery2_date": "8/22/2019 12:00:00 AM",
"origin": {
"name": "ESTES EXPRESS BOSTON-080",
"nbr": "0800780108",
"phone": "508-513-0120",
"email": "",
"address1": "215 BODWELL ST",
"city": "AVON",
"state": "MA",
"zip_postal_code": "02322",
"country": "US"
},
"dest": {
"name": "JOSEPH VINOGRAD",
"nbr": "",
"phone": "",
"email": "",
"address1": "14 CORTLAND DR",
"city": "Sharon",
"state": "MA",
"zip_postal_code": "02067",
"country": "US"
},
"piece_count": "2",
"dangerous_goods": "0",
"weight": 190
}
}
Code for class
public class OrderDTO
{
public class Origin
{
public string name { get; set; }
public string nbr { get; set; }
public string phone { get; set; }
public string email { get; set; }
public string address1 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string zip_postal_code { get; set; }
public string country { get; set; }
}
public class Dest
{
public string name { get; set; }
public string nbr { get; set; }
public string phone { get; set; }
public string email { get; set; }
public string address1 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string zip_postal_code { get; set; }
public string country { get; set; }
}
public class Shipment
{
public string hawb { get; set; }
public string service_level { get; set; }
public string status { get; set; }
public string description { get; set; }
public string service_level_code { get; set; }
public string delivery_date { get; set; }
public string delivery2_date { get; set; }
public Origin origin { get; set; }
public Dest dest { get; set; }
public string piece_count { get; set; }
public string dangerous_goods { get; set; }
public double weight { get; set; }
}
public class RootObject
{
public string token { get; set; }
public Shipment shipment { get; set; }
}
}

You can add username and password to your OrderDTO class (or another class containing these three objects) and then change action definition like:
public HttpResponseMessage AddOrder(OrderDRO input).
Then you don't need to use json serialization and easily you can do your logic.

JSON to C# classes Issue

I am fairly new to working with JSON and I have a bit of an issue with a JSON response I am getting from a web service. I've tried a bunch of online "JSON to c# class" generators and none of them seem to work with this specific bit of JSON. I am working with the Pocket API and the response I get below. Can anyone point me in the right direction for formatting this in to classes?

Thanks for any pointers,

A little bit tricky, but this should work. ( Because of the property names like 229279689)
var result = JsonConvert.DeserializeObject<Root>(json);

public string item_id { get; set; }
public string image_id { get; set; }
public string src { get; set; }
public string width { get; set; }
public string height { get; set; }
