Null value when mapping from Object.Property to Property with AutoMapper

Null value when mapping from Object.Property to Property with AutoMapper - c#

I want to map Message to MessageDto, so in RoomRead response I will have Collection of MessageDto with Username == User.LastName
public class RoomReadDTO
{
public int Id { get; set; }
public string Name { get; set; }
public bool Type { get; set; }
public ICollection<MessageDTO> Messages { get; set; }
}
public class MessageDTO
{
public int Id { get; set; }
public string Username { get; set; }
public string Content { get; set; }
public DateTime Date { get; set; }
}
public class Message
{
public int Id { get; set; }
public string Content { get; set; }
public DateTime Date { get; set; }
public int UserId { get; set; }
public int RoomId { get; set; }
public User User { get; set; }
public Room Room { get; set; }
}
public class User
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Photo { get; set; }
public ICollection<Participants> Participations { get; set; } = new List<Participants>();
public ICollection<Message> Messages { get; set; } = new List<Message>();
}
With this AutoMapper configuration
CreateMap<Message, MessageDTO>()
.ForMember(dest => dest.Username, opt => opt.MapFrom(message => message.User.LastName));
But in response Username property is null
{
"id": 1,
"name": "Private Chat John",
"type": false,
"messages": [
{
"id": 1,
"username": null,
"content": "Hello!",
"date": "2022-12-25T10:30:50"
},
{
"id": 2,
"username": null,
"content": "Hi!",
"date": "2022-12-25T10:32:50"
}
]
}
Can anyone give me some advice?

Deserialize Complex/Branched JSON and accessing branches

I have a JSON response which i generated a model from. the JSON data has various branches with data as shown below.
{

"customers": [
{
"district": null,
"feeder": "XXXXXXXXXXX",

}
},
"responseCode": 200,
"status": "true"
},
"status": true
}
}
],
"row_count": 2
}
}
I have various branches in this JSON response which i need to use. i generated a model class from this JSON as shown below
// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
public class Customer
{
public object 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 string oldaccountnumber { get; set; }
public string odoo_account_number { get; set; }
public string customername { get; set; }
public string address { get; set; }
public string phone { get; set; }
public string tarrif { get; set; }
public string tariff_category { get; set; }
public string service_band { get; set; }
public string status { get; set; }
public string status_period { get; set; }
public object payment_status { get; set; }
public string arrears { get; set; }
public string long_x { get; set; }
public string lat_y { 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 string lastName { get; set; }
public string address { get; set; }
public string city { get; set; }
public string district { get; set; }
public string userCategory { get; set; }
public string customerType { get; set; }
public string paymentPlan { get; set; }
public int vat { get; set; }
public string tariffCode { get; set; }
public double tariffRate { get; set; }
public int arrearsBalance { 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 Customer customer { get; set; }
public int responseCode { get; set; }
public string status { get; set; }
}
public class Result
{
public ObservableCollection<Customer> customers { 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; }
}
Afterwards i used the C# code to deserialize the JSON as shown below
Root myroot = JsonConvert.DeserializeObject<Root>(readTask);
ObservableCollection<Customer> data = myroot.result.customers;
This works fine, however, i am stuck with just customer Data. I want to be able to get the Transactional details (Customer2) and Lastpayment branches in a collection view. how can i achieve this? Thanks

You can parse your json and read it by linq. ToObject method help you to convert nodes to specific class.
I have taken json text in InputJson variable and then paresed it.
var parsed = JObject.Parse(InputJson);
var innerNodes = JArray.Parse(parsed["result"]["customers"].ToString());
var CustomerList = innerNodes.Select(x => x.ToObject<Customer>()).ToList();
And if you need just some of properties you can use in this way
var CustomerList = innerNodes.Select(x =>
new Customer
{
district = x["district"],
feeder = x["feeder"].ToString(),
transactional_details =x["transactional_details"].ToObject<TransactionalDetails>()
})
.ToList();
If you have different nodes in your object , you can call nodes and check them not be null!
var CustomerList = innerNodes.Select(x => new
{
district = x["district"],
feeder = x["feeder"].ToString(),
transactional_details =x["transactional_details"]?.ToObject<TransactionalDetails>(),
Lastpayment = x["transactional_details"]?["queryresult"]?["customer"]?["lastpayment"]?.ToObject<Lastpayment>(),
billedAmount = x["transactional_details"]?["queryresult"]?["customer"]?["billedAmount"] ?.ToString()
}).ToList();

Customers is an array object so you must iterate through this array.
For example this would work:
Root myroot = JsonConvert.DeserializeObject<Root>(json);
myroot.result.customers.ToList().ForEach(c =>
{
Console.WriteLine(c.transactional_details.queryresult.customer.lastpayment.amountPaid);
});
Looking at Locals in vs debugger for
var customers = myroot.result.customers.ToList();
we get this:

fix Queryresult class by changing Customer to Customer2
public class Queryresult
{
public string responseMessage { get; set; }
public Customer2 customer { get; set; }
public int responseCode { get; set; }
public string status { get; set; }
}
now you can get a lastpayment
Root myroot = JsonConvert.DeserializeObject<Root>(readTask);
LastPayment lastPayment = myroot.result.customers
.Select(c=>c.transactional_details.queryresult.customer.lastpayment).FirstOrDefault();
how to use
var amountPaid = lastPayment.amountPaid; //1000
var invoiceNumber = lastPayment.invoiceNumber; //17289583

Querying Json with Linq, Cannot access child value

I am new to C# with JSON. I would like to select with Nvidia API, the "featuredProduct" part, but I have an error
Cannot access child value on Newtonsoft.Json.Linq.JProperty.
This code works for the "searchedProducts" part.
Can you explain to me why?
const string url = "";
const int refresh = 3000;
string json = getGpuFromNvidia(url);
var jsonParse = JObject.Parse(json);
var result = jsonParse["searchedProducts"]["featuredProduct"]
.Where(n => n["isFounderEdition"].Value<bool>() == true)
.Select(p => new CarteGraphique
{
displayName = (string)p["displayName"],
prdStatus = (string)p["prdStatus"],
directPurchaseLink = (string)p["retailers"][0]["directPurchaseLink"]
})
.ToList();

I tested this code in VS
string json = ...your code
var jsonObj = JsonConvert.DeserializeObject<NvidiaRoot>(json);
var result = jsonObj.searchedProducts.productDetails
.Where(n => n.isFounderEdition)
.Select(p => new
{
displayName = p.displayName,
prdStatus = p.prdStatus,
directPurchaseLink = p.retailers[0].directPurchaseLink
})
.ToList();

You can try the below code.
To get the Featured Product. Sample Working code Here
var jsonParse = JObject.Parse(json);
var featuredProduct = jsonParse["searchedProducts"]["featuredProduct"];
var f = new CarteGraphique
{
displayName = featuredProduct["displayName"].ToString(),
prdStatus = featuredProduct["prdStatus"].ToString(),
directPurchaseLink = featuredProduct["retailers"][0]["directPurchaseLink"].ToString()
};
Console.WriteLine("Featured Product Details : " + f.displayName + ", " + f.prdStatus + ", " + f.directPurchaseLink);

Any help greatly appreciated

and you'd deserialize like this
Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
Always try to see references when creting json objects, I use this page
As commmented below, this would be the main:
using Newtonsoft.Json;
using System;
using System.IO;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
Root myDeserializedClass = JsonConvert.DeserializeObject<Root> (File.ReadAllText(#"response.json"));
foreach (var issue in myDeserializedClass.issues)
{
string id = issue.id.ToString();
string key = issue.key.ToString();
string summary = issue.fields.summary.ToString();
string creatoremail = issue.fields.creator.emailAddress.ToString();
}
}
}
}
I think the problem you're having might be the way you're writting your foreach? I mean the code seems to be lacking something, but perhaps you shortened it.

Net Core - AutoMapper an entity with his parent

I've tried to automap an entity with his parent but it's not working as I expected.
I have a company which can have some categories.
When I tried to get my category and his company inside, I have some fields I don't want to get (for example the siret, the connections or the passwords fields).
This is the result :
{
"id": 2,
"name": "Toot3",
"products": [],
"company": {
"id": 1,
"siret": "10000000000000",
"name": "Tootland",
"postal": 33000,
"city": "Bordeaux",
"country": "France",
"address": null,
"mail": "xxx",
"status": "waiting",
"created": "2020-07-08T18:51:52.051339",
"lastConnection": "2020-07-13T20:41:05.1292985",
"passwordHash": "xxx",
"passwordSalt": "xxx",
"categs": []
},
"companyId": 1
}
My request to get all the categories and his parent :
public async Task<IEnumerable<Categ>> GetAllWithProducts()
{
return await _context.Categ
.Include(cm => cm.Products)
.Include(cm => cm.Company)
.ToListAsync();
}
This is my company class :
public class Company
{
public const string STATUS_WAITING = "waiting";
public const string STATUS_VALIDATED = "validated";
public const string STATUS_REJECTED = "rejected";
public int Id { get; set; }
public string Siret { get; set; }
public string Name { get; set; }
public int Postal { get; set; }
public string City { get; set; }
public string Country { get; set; }
public string Address { get; set; }
public string Mail { get; set; }
public string Status { get; set; }
public DateTime Created { get; set; }
public DateTime LastConnection { get; set; }
public byte[] PasswordHash { get; set; }
public byte[] PasswordSalt { get; set; }
public ICollection<Categ> Categs { get; set; }
}
Then my categ class :
public class CategMagazine
{
public int Id { get; set; }
public string Name { get; set; }
public ICollection<Product> Products { get; set; }
public Company Company { get; set; }
public int CompanyId { get; set; }
}
An extract of my AutoMapperProfiles class :
CreateMap<Company, CompanyForListDto>();
CreateMap<Categ, CategForListDto>()
.ForMember(dest => dest.Company,
opt => opt.MapFrom(src => src.Company));
The CompanyForListDto
public class CompanyForListDto
{
public string Name { get; set; }
public int Postal { get; set; }
public string City { get; set; }
public string Country { get; set; }

Deserialize JSON with mixture of dynamic and static keys

I have a JSON object with a dynamic key for the properties I wish to map to a class. I'm uncertain how to build my class to deserialize with JSON.NET. I need the values from the 'results' and 'more' keys at the upper level and also the the values from the 'timesheets' key.
Here is my JSON data.
{
"results": {
"timesheets": {
"7994790": {
"id": 7994790,
"user_id": 165502,
"jobcode_id": 11267673,
"start": "2019-12-20T05:48:00-05:00",
"end": "2019-12-20T13:44:00-05:00",
"duration": 28560,
"date": "2019-12-20",
"tz": -5,
"tz_str": "tsET",
"type": "regular",
"location": "Android App",
"on_the_clock": false,
"locked": 0,
"notes": "",
"customfields": {
"20251": "",
"19647": "Laborer",
"20327": "",
"19648": ""
},
"last_modified": "2019-12-20T20:28:48+00:00",
"attached_files": [],
"created_by_user_id": 165502
},
"8087496": {
"id": 8087496,
"user_id": 165502,
"jobcode_id": 2415904,
"start": "2019-12-20T13:44:00-05:00",
"end": "2019-12-20T15:11:00-05:00",
"duration": 5220,
"date": "2019-12-20",
"tz": -5,
"tz_str": "tsET",
"type": "regular",
"location": "Android App",
"on_the_clock": false,
"locked": 0,
"notes": "",
"customfields": {
"20251": "",
"19647": "Laborer",
"20327": "",
"19648": ""
},
"last_modified": "2019-12-20T20:28:49+00:00",
"attached_files": [],
"created_by_user_id": 165502
}
}
},
"more": false
}
And my classes as I currently have them which returns this error.
System.ArgumentNullException: 'Value cannot be null.
Parameter name: values'
public class RootObject
{
public Results results { get; set; }
public bool more { get; set; }
}
public class Results
{
public Timesheets timesheets { get; set; }
}
public class Timesheets
{
public Dictionary<int, TimesheetDetails> timesheetsdetails { get; set; }
}
public class TimesheetDetails
{
public int id { get; set; }
public int user_id { get; set; }
public int jobcode_id { get; set; }
public DateTime start { get; set; }
public DateTime end { get; set; }
public int duration { get; set; }
public string date { get; set; }
public int tz { get; set; }
public string tz_str { get; set; }
public string type { get; set; }
public string location { get; set; }
public bool on_the_clock { get; set; }
public int locked { get; set; }
public string notes { get; set; }
public DateTime last_modified { get; set; }
public List<object> attached_files { get; set; }
public int created_by_user_id { get; set; }
}
var stuff = JsonConvert.DeserializeObject<RootObject>(result.Content);
Console.WriteLine(string.Join(",", stuff.results.timesheets.timesheetsdetails));

First of all your json is not valid. After the end of the first timesheet data, there should be a , You can use any json validator online simply to validate it.
And in your model the Results is not valid according to the json. The below one works for me.
public class Response
{
[JsonProperty("results")] public TimeSheetResponse TimeSheetResponse { get; set; }
[JsonProperty("more")] public bool More { get; set; }
}
public class TimeSheetResponse
{
[JsonProperty("timesheets")] public Dictionary<string, Timesheet> Timesheets { get; set; }
}
public class Timesheet
{
[JsonProperty("id")]
public long Id { get; set; }
[JsonProperty("user_id")]
public long UserId { get; set; }
[JsonProperty("jobcode_id")]
public long JobcodeId { get; set; }
[JsonProperty("start")] public DateTimeOffset Start { get; set; }
[JsonProperty("end")] public DateTimeOffset End { get; set; }
[JsonProperty("duration")] public long Duration { get; set; }
[JsonProperty("date")] public DateTimeOffset Date { get; set; }
[JsonProperty("tz")] public long Tz { get; set; }
[JsonProperty("tz_str")] public string TzStr { get; set; }
[JsonProperty("type")] public string Type { get; set; }
[JsonProperty("location")] public string Location { get; set; }
[JsonProperty("on_the_clock")] public bool OnTheClock { get; set; }
[JsonProperty("locked")] public long Locked { get; set; }
[JsonProperty("notes")] public string Notes { get; set; }
[JsonProperty("customfields")] public Dictionary<string, string> Customfields { get; set; }
[JsonProperty("last_modified")] public DateTimeOffset LastModified { get; set; }
[JsonProperty("attached_files")] public List<object> AttachedFiles { get; set; }
[JsonProperty("created_by_user_id")]
public long CreatedByUserId { get; set; }
}
To deserialize to Object..
var timeSheetResult = JsonConvert.DeserializeObject<Response>(data);
