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

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?

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();
OUTPUT

UPDATE
if you need just a feature product
var featuredProduct = jsonObj.searchedProducts.featuredProduct;
var result = new
{
displayName = featuredProduct.displayName,
prdStatus = featuredProduct.prdStatus,
directPurchaseLink = featuredProduct.retailers[0].directPurchaseLink
};

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);

Deserialize JSON to List

I have this Json:
{
"trades": [
{

And Classes:
public class TakeProfitOrder
{
public string id { get; set; }
public string createTime { get; set; }
public string type { get; set; }
public string tradeID { get; set; }
public string price { get; set; }
public string timeInForce { get; set; }
public string triggerCondition { get; set; }
public string state { get; set; }
}
public class Trade
{
public string id { get; set; }
public string instrument { get; set; }
public string price { get; set; }
public string openTime { get; set; }
public string initialUnits { get; set; }
public string initialMarginRequired { get; set; }
public string state { get; set; }

public TakeProfitOrder takeProfitOrder { get; set; }
}
public class RootObject
{
public List<Trade> trades { get; set; }
public string lastTransactionID { get; set; }
}
I deserialize with :
var result = JsonConvert.DeserializeObject<RootObject>(Json);
var price = result.trades.Select(p => p.price).ToList();
price.ForEach(Console.WriteLine);
It works. I can access "price" in "trades", but I do not know how to access the "price" in "takeProfitOrder". I need the value of "price" from "takeProfitOrder" in to a list. I am sure it is something very simple but I cannot figure out how to do it, even after looking at some similar examples.
Can somebody please help me?

It's simple
result.trades.Select(p => p.takeProfitOrder.price)
You should understand better from this example
foreach (Trade trade in result.trades)
{
TakeProfitOrder takeProfitOrder = trade.takeProfitOrder;
Console.WriteLine(takeProfitOrder.price);
}

C# - How convert json string to class

How can I convert my json-string to class
this is my json
{
"$id": "1",
"Result": {
"$id": "2",
"dateTime": 23821964,
"list": [{
"$id": "3",
"UserId": 302,

"Title": "شیدکو",
"Sender": "شیدکو",
"Answer": "",
"Comment": "test 2",
"ProductTitle": null,
"CommentId": 77,
"Logo": "http://example.com/Commercial/User/302/Logo/tmpF0BF.jpg",
"Date": 24302057,
"AnswerDate": -2123661683,
"AnswerEdit": false,
"CommentEdit": false,
"ForfeitCount": 0,
"RewardCount": 0,
"ThisCountReport": 2,
"Reported": [{

"ForfeitCount": 0,
"RewardCount": 0
}, {
"$id": "5",
"BlockerId": 355,
"Title": "محتوای غیر مرتبط",
"Date": -19527382,
"ForfeitCount": 0,
"RewardCount": 0
}],
"Gem": 0
}, {
"$id": "6",
"UserId": 302,

"AnswerDate": -2123661683,
"AnswerEdit": false,
"CommentEdit": false
}]
},
"StatusCode": "Created",
"Description": null
}
And I do these step, but nothing happens
JObject json1 = JObject.Parse(strMyJson);
_CommentAdmindto flight = Newtonsoft.Json.JsonConvert.DeserializeObject<_CommentAdmindto>(json1.ToString());
_CommentAdmindto deserializedProduct = JsonConvert.DeserializeObject<_CommentAdmindto>(json);
_CommentAdmindto deserializedProduct1 = ConvertJsonToClass<_CommentAdmindto>(strMyJson);
JsonSerializer serializer = new JsonSerializer();
_CommentAdmindto p = (_CommentAdmindto)serializer.Deserialize(new JTokenReader(strMyJson), typeof(_CommentAdmindto));
And here is my class and function:
public static T ConvertJsonToClass<T>( string json)
{
System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
return serializer.Deserialize<T>(json);
}
}
public class _CommentAdmindto
{
public long dateTime { get; set; }
public IQueryable<CommentDtoAdmin> list { get; set; }
}
public class CommentDtoAdmin
{
public long UserId { get; set; }
public string UID { get; set; }
public string Title { get; set; }
public string Sender { get; set; }
public string Answer { get; set; }
public string Comment { get; set; }
public string ProductTitle { get; set; }
public long CommentId { get; set; }
public string Logo { get; set; }
public long Date { get; set; }
public long AnswerDate { get; set; }
public bool AnswerEdit { get; set; }
public bool CommentEdit { get; set; }
}

Your model should be similar to this (For invalid c# names, you can use JsonProperty attribute) :
public class Reported
{
[JsonProperty("$id")]
public string id { get; set; }
public int BlockerId { get; set; }
public string Title { get; set; }
public int Date { get; set; }
public int ForfeitCount { get; set; }
public int RewardCount { get; set; }
}
public class List
{
[JsonProperty("$id")]
public string id { get; set; }
public int UserId { get; set; }
public string UID { get; set; }
public string Title { get; set; }
public string Sender { get; set; }
public string Answer { get; set; }
public string Comment { get; set; }
public object ProductTitle { get; set; }
public int CommentId { get; set; }
public string Logo { get; set; }
public int Date { get; set; }
public int AnswerDate { get; set; }
public bool AnswerEdit { get; set; }
public bool CommentEdit { get; set; }
public int ForfeitCount { get; set; }
public int RewardCount { get; set; }
public int ThisCountReport { get; set; }
public List<Reported> Reported { get; set; }
public int Gem { get; set; }
}
public class Result
{
[JsonProperty("$id")]
public string id { get; set; }
public int dateTime { get; set; }
public List<List> list { get; set; }
}
public class RootObject
{
[JsonProperty("$id")]
public string id { get; set; }
public Result Result { get; set; }
public string StatusCode { get; set; }
public object Description { get; set; }
}
Now you can deserialize as
var result = JsonConvert.DeserializeObject<RootObject>(jsonstring);
BTW: http://json2csharp.com/ can help to guess your model when working with json.

You seem to be trying to deserialize in a lot of different ways but you don't have a full structure to actually match the json. You miss the outer class (representing the full object) and at least Newtonsoft.Json cannot deserialize to an IQueryable so I changed that to IEnumerable.
string strMyJson = "{\"$id\":\"1\",\"Result\":{\"$id\":\"2\",\"dateTime\":23826985,\"list\":[{\"$id\":\"3\",\"UserId\":302,\"UID\":\"302_UID\",\"Title\":\"شیدکو\",\"Sender\":\"شیدکو\",\"Answer\":\"\",\"Comment\":\"test 2\",\"ProductTitle\":null,\"CommentId\":77,\"Logo\":\"http://www.domain.com/Commercial/User/302/Logo/tmpF0BF.jpg\",\"Date\":24307078,\"AnswerDate\":-2123656662,\"AnswerEdit\":false,\"CommentEdit\":false,\"ForfeitCount\":0,\"RewardCount\":0,\"ThisCountReport\":2,\"Reported\":[{\"$id\":\"4\",\"BlockerId\":355,\"Title\":\"محتوای غیر اخلاقی\",\"Date\":-19527396,\"ForfeitCount\":0,\"RewardCount\":0},{\"$id\":\"5\",\"BlockerId\":355,\"Title\":\"محتوای غیر مرتبط\",\"Date\":-19527382,\"ForfeitCount\":0,\"RewardCount\":0}],\"Gem\":0},{\"$id\":\"6\",\"UserId\":302,\"UID\":\"302_UID\",\"Title\":\"شیدکو\",\"Sender\":\"شیدکو\",\"Answer\":\"\",\"Comment\":\"test 2\",\"ProductTitle\":null,\"CommentId\":77,\"Logo\":\"http://www.domain.com/Commercial/User/302/Logo/tmpF0BF.jpg\",\"Date\":24307078,\"AnswerDate\":-2123656662,\"AnswerEdit\":false,\"CommentEdit\":false}],\"StatusCode\":\"Created\",\"Description\":null}}";
var result = JsonConvert.DeserializeObject<Wrapper>(strMyJson);
with classes looking like this:
public class Wrapper
{
public _CommentAdmindto Result { get; set; }
}
public class _CommentAdmindto
{
public long dateTime { get; set; }
public IEnumerable<CommentDtoAdmin> list { get; set; }
}
CommentDtoAdmin is looking the same.
Though I must say that this only helps you with the deserialization.

Firstly, the $id" properties are synthetic properties added by Json.NET to track and preserve multiple references to the same object. For details, see PreserveReferencesHandling setting.
Thus, if you temporarily remove the "$id" properties, you can upload your JSON to http://json2csharp.com/ and get the following data model:
public class Reported
{
public int BlockerId { get; set; }
public string Title { get; set; }
public int Date { get; set; }
public int ForfeitCount { get; set; }
public int RewardCount { get; set; }
}
public class CommentDtoAdmin
{
public int UserId { get; set; }
public string UID { get; set; }
public string Title { get; set; }
public string Sender { get; set; }
public string Answer { get; set; }
public string Comment { get; set; }
public object ProductTitle { get; set; }
public int CommentId { get; set; }
public string Logo { get; set; }
public int Date { get; set; }
public int AnswerDate { get; set; }
public bool AnswerEdit { get; set; }
public bool CommentEdit { get; set; }
public int ForfeitCount { get; set; }
public int RewardCount { get; set; }
public int ThisCountReport { get; set; }
public List<Reported> Reported { get; set; }
public int Gem { get; set; }
}
public class Result
{
public int dateTime { get; set; }
public List<CommentDtoAdmin> list { get; set; }
}
public class RootObject
{
public Result Result { get; set; }
public string StatusCode { get; set; }
public string Description { get; set; }
}
I then modified the returned model as follows:
I used the name CommentDtoAdmin for the list type.
I set the type of the Description property to string.
Now your JSON can be deserialized and re-serialized as follows:
var settings = new JsonSerializerSettings
{
PreserveReferencesHandling = PreserveReferencesHandling.Objects,
};
var root = JsonConvert.DeserializeObject<RootObject>(json1, settings);
var json2 = JsonConvert.SerializeObject(root, Formatting.Indented, settings);
Note that Json.NET has no built-in logic for deserializing the interface IQueryable<T> to a concrete type, so I had to leave the property as public List<CommentDtoAdmin> list { get; set; }. You can always generate a queryable from the list using AsQueryable():
var queryable = root.Result.list.AsQueryable();
Sample fiddle.

I think you json string does not have correct syntax. It looks like a ']' (end of Array) and a final '}' is missing.
That's what the Visual Studio editor told me when making a json file out of your string after removing all the '\'

Issues with deserializing Json in C#

I have some json like this:
{

public string root_transaction_id { get; set; }
}
public class Result
{
public string #type { get; set; }
public string barcode { get; set; }
public string bsp { get; set; }
public string dpid { get; set; }
public string postcode { get; set; }
public string state { get; set; }
public string suburb { get; set; }
public string city { get; set; }
public string country { get; set; }
}
public class SearchParameters
{
}
Finally, I use these code to get Json data:
string result = "Above json";
JavaScriptSerializer json = new JavaScriptSerializer();
Address add = json.Deserialize<Address>(result);
I see that, add.status, add.search_date... etc have values, but add.results is null.
What is wrong with my code?

I think the issue is using #type as illegal identifier. Try using [DataMember(Name = "#type")] before public string #type { get; set; }. Add a [DataContract] before public class Address.
Hence, your final code will be,
[DataContract]
public class Result
{
[DataMember(Name = "#type")]
public string #type { get; set; }
public string barcode { get; set; }
public string bsp { get; set; }
public string dpid { get; set; }
public string postcode { get; set; }
public string state { get; set; }
public string suburb { get; set; }
public string city { get; set; }
public string country { get; set; }
}
