Add item to JSON array section in C#

{
"name": "Not Okay Bears Solana #1",
"image": "ipfs://QmV7QPwmfc6iFXw2anb9oPZbkFR75zrtw6exd8LherHgvU/1.png",
"attributes": [
{
"trait_type": "Background",
"value": "Amethyst"
},
{
"trait_type": "Fur",
"value": "Warm Ivory"
},
{
"trait_type": "Mouth",
"value": "Clean Smile"
},
{
"trait_type": "Eyes",
"value": "Not Okay"
},
{
"trait_type": "Hat",
"value": "Bucket Hat"
},
{
"trait_type": "Clothes",
"value": "Plaid Jacket"
},
{
"trait_type": "Eyewear",
"value": "Plastic Glasses"
}
],
"description": "Not Okay Bears Solana is an NFT project for mental health awareness. 10k collection on the Polygon blockchain. We are not okay."
}
I need to add an object to attributes.
How to do this?
My JSON classes:
public class Attribute
{
public string trait_type { get; set; }
public string value { get; set; }
}
public class Root
{
public string name { get; set; }
public string image { get; set; }
public List<Attribute> attributes { get; set; }
public string description { get; set; }
}

try this, in this case you don't need any classes
var jsonObject = JObject.Parse(json);
JObject obj = new JObject();
obj.Add("trait_type", "type");
obj.Add("value", "value");
((JArray)jsonObject["attributes"]).Add(obj);
var newJson=jsonObject.ToString();
but if you need the data not a json , you can use this code
Root data = JsonConvert.DeserializeObject<Root>(json);
data.attributes.Add(new Attribute { trait_type="type", value="value"});

Generating HMAC signature

I am trying to generate the HMAC signature. This is for a validation with credit card company. Below is my code to generate the HMAC signature:
public string APISecurityKey(Identity postParameters)
{
String secretAccessKey = "secretkey";
string data = "message";
byte[] secretKey = Encoding.UTF8.GetBytes(secretAccessKey);
HMACSHA256 hmac = new HMACSHA256(secretKey);
hmac.Initialize();
byte[] bytes = Encoding.UTF8.GetBytes(data);
byte[] rawHmac = hmac.ComputeHash(bytes);
return Convert.ToBase64String(rawHmac);
}
They are asking me to substitute the message field with the JSON request (JSON supplied should have all carriage return newline sequences replaced with a space character). My object looks like so:
public class Identity
{
public List<Header> header { get; set; }
public string firstName { get; set; }
public string LastName { get; set; }
public string middleName { get; set; }
public string address { get; set; }
public string mothersName { get; set; }
public string DriversLic { get; set; }
public DateTime insertTime { get; set; }
public string Status { get; set; }
public string city { get; set; }
public string state { get; set; }
public string zip { get; set; }
public DateTime UpdatedOn { get; set; }
}
}
public class Header
{
public string tenantId { get; set; }
public string requestType { get; set; }
public string clientReferenceId { get; set; }
public string expRequestId { get; set; }
public string txnId { get; set; }
public string messageTime { get; set; }
public string options { get; set; }
}
The example given to me for the message is like this:
{"tenantId": "TENANT1","request Type": "Simulator","clientRefere
nceId": "Hunter + ProveID","expRequestId": "333","messageTim
e": "2016-08-04T22:13:07Z","options": {"workflow": "wf1","model
Type":"mt1","responseType":1,"Responses": {…}}}
I am not sure how to include tenantId, tenantId, expRequestId, options as part of my JSON message. I am very new to JSON. I have this partial code:
public static async Task createJSON( Identity postParameters)
{
var tmpRequest = new HttpRequestMessage();
tmpRequest.Content = new StringContent(JsonConvert.SerializeObject(postParameters));
tmpRequest.Content.Headers.Add("tenantId", "V123456");
tmpRequest.Content.Headers.Add("requestType", "PreciseIdOnly");
}
postParameters is my Identity object with values. How can I create that JSON that includes tenantId, tenantId, expRequestId and the object so that I can put that JSON value in the message of APISecurityKey method. Below is the test JSON file that I need to create:
{
"header": {
"tenantId": "V123456",
"requestType": "Precise",
"clientReferenceId": "11111111",
"RequestId": "",
"txnId": "",
"messageTime": "2020-05-28T00:00:02Z",
"options": {}
},
"payload": {
"control": [
{
"option": "SUBSCRIBER_PREAMBLE",
"value": "wer"
},
{
"option": "SUBSCRIBER_OPERATOR_INITIAL",
"value": "WS"
},
{
"option": "SUBSCRIBER_SUB_CODE",
"value": "1111111"
},
{
"option": "PID_USERNAME",
"value": "demo"
},
{
"option": "PID_PASSWORD",
"value": "password"
},
{
"option": "PRODUCT_OPTION",
"value": "11"
}
],
"contacts": [{
"id": "APPLICANT_CONTACT_ID_1",
"person": {
"typeOfPerson": "",
"personIdentifier": "",
"personDetails": {
"dateOfBirth": "1990-12-11",
"yearOfBirth": "",
"age": "",
"gender": "",
"noOfDependents": "",
"occupancyStatus": "",
"mothersMaidenName": "",
"spouseName": ""
},
"names": [{
"id": "",
"firstName": "Test1",
"middleNames": "D",
"surName": "Test2",
"nameSuffix": ""
}]
},
"addresses": [{
"id": "Main_Contact_Address_0",
"addressType": "CURRENT",
"poBoxNumber": "",
"street": "2312 Test Drve",
"street2": "",
"postTown": "test",
"postal": "49548",
"stateProvinceCode": "CA"
}],
"identityDocuments": [{
"documentNumber": "123456789",
"hashedDocumentNumber": "",
"documentType": "SSN"
}]
}]
}
}
I want to generate the same JSOn as the sample above in C# using the objects.
any help will be highly appreciated.

If you using Visual studio, you can create the JSON by going to Edit menu and paster JSON as class. This will create all the classes for you and then you can assign values to the classes by instantiating them

Getting Data from a JObject

I have stored JSON data in a string and by using the JObject, I am trying to get values from JSON data. I am just not able to figure out that what is the underlying issue with my code because I am not able to get data from the JSON object. A snippet of my code is attached below. If some can help me out to figure out the issue it will be immensely appreciated.
String text;
try {
var response = (HttpWebResponse)request.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{
text = sr.ReadToEnd();
JObject jObject = JObject.Parse(text);
string haha = (string)jObject["value/segments/requests/count/sum"];
ViewBag.gotstring = haha;
}
System.Diagnostics.Debug.WriteLine(text);
} catch(Exception e) {
System.Diagnostics.Debug.WriteLine(url);
System.Diagnostics.Debug.WriteLine(e.ToString()); }
return View();
Here is the JSON:
{
"value": {
"start": "2018-08-12T04:44:38.941Z",
"end": "2018-08-12T16:44:38.941Z",
"interval": "PT30M",
"segments": [
{
"start": "2018-08-12T14:00:00Z",
"end": "2018-08-12T14:30:00Z",
"segments": [
{
"requests/count": {
"sum": 2
},
"request/name": "GET Home/Index"
},
{
"requests/count": {
"sum": 1
},
"request/name": "GET Home/About"
},
{
"requests/count": {
"sum": 1
},
"request/name": "GET Home/Contact"
}
]
},
{
"start": "2018-08-12T14:30:00Z",
"end": "2018-08-12T15:00:00Z",
"segments": [
{
"requests/count": {
"sum": 2
},
"request/name": "GET Account/Register"
},
{
"requests/count": {
"sum": 1
},
"request/name": "GET Account/Login"
}
]
},
{
"start": "2018-08-12T15:30:00Z",
"end": "2018-08-12T16:00:00Z",
"segments": [
{
"requests/count": {
"sum": 8
},
"request/name": "GET Home/Index"
},
{
"requests/count": {
"sum": 8
},
"request/name": "GET Home/About"
}
]
}
]
}
}

jObject does not work this way. It returns dictionary that you can query by key, but keys are single level. I.e. you'll be able to get some data like this:
var haha = jObject["value"]["segments"];
But beyond that it gets very complex. You'll be much better off defining a C# class that represents your JSON and serialise into that. A simple `Edit=>Paste Special => JSON as Class" in Visual Studio gives this:
public class Rootobject
{
public Value value { get; set; }
}
public class Value
{
public DateTime start { get; set; }
public DateTime end { get; set; }
public string interval { get; set; }
public Segment[] segments { get; set; }
}
public class Segment
{
public DateTime start { get; set; }
public DateTime end { get; set; }
public Segment1[] segments { get; set; }
}
public class Segment1
{
[JsonProperty("requests/count")]
public RequestsCount requestscount { get; set; }
[JsonProperty("request/name")]
public string requestname { get; set; }
}
public class RequestsCount
{
public int sum { get; set; }
}
and then deserialise like this:
var serialised = JsonConvert.DeserializeObject<Rootobject>(json);
var haha = serialised.value.segments.FirstOrDefault().segments.FirstOrDefault().requestscount.sum;
And here is a working sample: https://dotnetfiddle.net/CZgMNE

Can you try:
EDIT: seems like segments is an array, this will get you the sum for first segment only
string haha = (string)jObject["value"]["segments"][0]["segments"]["requests/count"]["sum"];

How to Deserialize JSON array(or list) in C#

public static string DeserializeNames()
{
// Json I am passing for the deserialization.
JsonStream= "{
"head": {
"Rows": [
"test 1",
[
[
{
"#Key": "Domain",
"#value": "LocalHost"
},
{
"#Key": "Cookie name(s)",
"#value": "Google"
},
{
"#Key": "Purpose",
"#value": "Test"
},
{
"#Key": "lifetime",
"#value": "test"
}
]
]
]
}
}"
//deserialize JSON from file
JavaScriptSerializer serializer = new JavaScriptSerializer();
var cookieList = serializer.Deserialize<List<Cookie>>(JsonStream).ToList();
}
//Class descriptions
//I have created below classes for the deserialization. Records are not deserialized i am getting zero record count.
public class Categorization
{
public string categorizationName { get; set; }
public List<object> KeyValue{ get; set; }
}
public class Head
{
public IList<Categorization> Rows { get; set; }
}
public class Cookie
{
public Head head { get; set; }
}
Also created below set of the classes and tried the deserialization, Still no luck
public class Head
{
public List<object> Rows { get; set; }
}
public class Cookie
{
public Head head { get; set; }
}
I am getting count as 0 i am not able to fetch any record.
Please help !!

I have modified the Json as below and stored in in the file "test.json" :
{
"head": {
"TestRows": [
[
{
"Key": "Domain",
"value": "Google"
},
{
"Key": "Cookie",
"value": "Test"
},
{
"Key": "Use for",
"value": "Test."
},
{
"Key": "Expire Time",
"value": "1 hour"
}
]
]
}
}
And created below set of classes :
public class Head
{
public IList<List<Dictionary<string, object>>> TestRows{ get; set; }
}
public class Cookie
{
public Head Head { get; set; }
}
var baseDirectory = AppDomain.CurrentDomain.BaseDirectory;
var path= Path.Combine(baseDirectory, "test.json");
//deserialize JSON from file
string JsonStream = System.IO.File.ReadAllText(path, Encoding.Default);
var DeserializedCookieList = JsonConvert.DeserializeObject<Cookie>(JsonStream);
Deserialization is working properly.

How can I use regex to extract child node from JSON structure?

Hi I try to get json data inside of the json. But my class is Employee my service creates json as com.myteam.rbffiyatlama2.Employee this prefix can be changeable so I have to write a solution to get an exact part of the json Like below but my below code is not working. I will send my node name to a method Getjsonobject(Employee emp) or Getjsonobject(Customer cust) or Getjsonobject(Student student) etc.
My Json:
{
"type": "SUCCESS",
"msg": "Container RBFFiyatlama2_1.0.1 successfully called.",
"result": {"execution-results": {
"results": [
{
"value": 2,
"key": ""
},
{
"value": {"com.myteam.rbffiyatlama2.Employee": {
"salary": 2400,
"age": 35,
"cofactor": 0.2
}},
"key": "t1"
},
{
"value": {"com.myteam.rbffiyatlama2.Employee": {
"salary": 4800,
"age": 35,
"cofactor": 0.2
}},
"key": "t2"
}
],
"facts": [

"key": "t2"
}
]
}}
}
class Program
{
static void Main(string[] args)
{
var employee1 = new Employee() { age = 35, cofactor = 0.2, salary = 2000 };
var employee2 = new Employee() { age = 35, cofactor = 0.2, salary = 4000 };
var list = new List<Employee>();
list.Add(employee1);
list.Add(employee2);
var uri = new Uri("http://localhost:8080/kie-server/services/rest/server/containers/instances/RBFFiyatlama2_1.0.1");
var kieclient = new KieRequestWrapper<Employee>(uri, "kieserver", "#test2018", MethodType.POST, "application/json").Add(list).Run();
Console.Write(kieclient.Content);
var match = Regex.Match(kieclient.Content, #"(?*.Employee{*})");
var result= MyParser.Parse(match, typeof(Employee)); //Desired
Console.Read();

}
public class Employee

public double cofactor { get; set; }
public int salary { get; set; }
}

You don't want to use XPath to get the data you need, you want to deserialize the the JSON string into an object and then get the data you need. There are many JSON serialization libraries out there, the most common one, AFAIK, is JSON.NET. You can look at how deserialization works here: https://www.newtonsoft.com/json/help/html/DeserializeObject.htm
Example:
public class Account
{
public string Email { get; set; }
public bool Active { get; set; }
public DateTime CreatedDate { get; set; }
public IList<string> Roles { get; set; }
}
string json = #"{
'Email': 'james#example.com',
'Active': true,
'CreatedDate': '2013-01-20T00:00:00Z',
'Roles': [
'User',
'Admin'
]
}";
Account account = JsonConvert.DeserializeObject<Account>(json);
Console.WriteLine(account.Email);
// james#example.com
