How to remove $ for json result? - c#

I am trying to read a cell value from a simple google sheet
https://docs.google.com/spreadsheets/d/1opP1t_E9xfuLXBkhuyzo5j9k_xBNDx0XKb31JwLP1MM/edit?usp=sharing
then I published it and I get an API link that return JSON, check the following
https://spreadsheets.google.com/feeds/list/1opP1t_E9xfuLXBkhuyzo5j9k_xBNDx0XKb31JwLP1MM/1/public/values?alt=json
when I tried to generate C# classes from JSON using http://json2csharp.com/, I get
invalid_name and $ (which is not fine for csharp compiler)
public class Id
{
public string __invalid_name__$t { get; set; }

{

I want to serialize and deserialize this class, also i want to remove $,what i need to do?

Obviously json2csharp converts each json object into a class and converts the key names into variable names literally. So whenever it finds a key name starting with $ it can't create a c# variable with this character and it precedes the variable name with a _invalid_name_. There is nothing wrong here.
You should tell why do you want to remove this invalid_name phrase from variable name? do you want to serialize and deserialize this class? If so you could use NewtonSoft Json library and define those fields with $ sign like this:
[JsonProperty(PropertyName = "$t")]
public string t { get; set; }
this will allow you to serialize/deserialize the json doc
same for gsx$name:
[JsonProperty(PropertyName = "gsx$name")]
public string gsxname { get; set; }

Hello I have one json text inside this text there is one key which starts with $
string jsonText="{\"Version\":\"1.1\",\"Documents\":[{\"DocumentState\":\"Correct\",\"DocumentData\":{\"Name\":\"test\",\"$type\":\"Document\",\"Fields\":[{\"Name\":\"CustomerFullName\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"0\",\"RecognizedValue\":\"\",\"Value\":\"\"},{\"Name\":\"CustomerBirthDate\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"DocumentNumber\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"0000000000\",\"RecognizedValue\":\"\",\"Value\":\"\"},{\"Name\":\"CustomerIsMarried\",\"$type\":\"Checkmark\",\"IsSuspicious\":false,\"Value\":true},{\"Name\":\"CustomerCounty\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"CustomerArea\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"CustomerAddress\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"11000000\",\"RecognizedValue\":\"\",\"Value\":\"\"},{\"Name\":\"DocumentGUID\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"DocumentProposalID\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"DocumentCountry\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"000\",\"RecognizedValue\":\"FRA\",\"Value\":\"FRA\"},{\"Name\":\"DocumentCurrency\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"000\",\"RecognizedValue\":\"EUR\",\"Value\":\"EUR\"},{\"Name\":\"DocumentTo\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"DocumentFrom\",\"$type\":\"Text\",\"Value\":\"\"},{\"Name\":\"DocumentTotalNumberOfPages\",\"$type\":\"Text\",\"SuspiciousSymbols\":\"0\",\"RecognizedValue\":\"1\",\"Value\":\"1\"}]}}]}";
Console.WriteLine(jsonText);
var documentResult = JsonConvert.DeserializeObject<DocumentDTO>(jsonText);
and my class objects are below
public class DocumentDTO
{
public string Version { get; set; }
public List<DocumentInfo> Documents { get; set; }
}
public class DocumentInfo
{
public string DocumentState { get; set; }
public DocumentData DocumentData { get; set; }
public string DocumentAsBase64 { get; set; }
}
public class DocumentData
{
public string Name { get; set; }
[JsonPropertyName("$type")]
public string type { get; set; }
public List<DocumentField> Fields { get; set; }
}
public class DocumentField
{
public string Name { get; set; }
[JsonPropertyName("$type")]
public string type { get; set; }
public string SuspiciousSymbols { get; set; }
public string RecognizedValue { get; set; }
public string Value { get; set; }
}
but it is not working not converting $type to type. How can I solve this problem ?
Thanks in advance
Kind Regards

That's because you're using JsonConvert from Newtonsoft.Json library and are marking property with JsonPropertyName attribute from System.Text.Json.Serialization. The two just don't play well together. Try replacing your JsonPropertyName with JsonProperty attribute from Newtonsoft.Json and it should work.
public class DocumentData
{
public string Name { get; set; }
[JsonProperty("$type")]
public string Type { get; set; }
public List<DocumentField> Fields { get; set; }
}
public class DocumentField
{
public string Name { get; set; }
[JsonProperty("$type")]
public string Type { get; set; }
public string SuspiciousSymbols { get; set; }
public string RecognizedValue { get; set; }
public string Value { get; set; }
}

I'm trying to Deserialize some json using JsonConver.DeserializeObject. however it's not working on some json from the api I'm using. here is a link that does not work: https://api.pokemontcg.io/v1/cards?setCode=smp
and here is a link that does work. https://api.pokemontcg.io/v1/cards?setCode=sm2
I'm not sure why it sometimes works and sometimes not. The data that comes out of it is very similar to each other, just different cards.
Here is the code:
public static async Task<T> GetDataAsync<T>(this HttpClient client, string address, string querystring)
where T : class
{
var uri = address;
if (!string.IsNullOrEmpty(querystring))
{
uri += querystring;
}
var httpMessage = await client.GetStringAsync(uri);
var jsonObject = JsonConvert.DeserializeObject<T>(httpMessage);
return jsonObject;
}
Now my card class
namespace CardAppReal.Lib.Models
{
public class Card
{
public string id { get; set; }
public string name { get; set; }
public string imageUrl { get; set; }
public string imageUrlHiRes { get; set; }
public string supertype { get; set; } // if pokemon, trainer or energy
public string setcode { get; set; }
public int number { get; set; }
public string set { get; set; }
}
}
With a root
using System.Collections.Generic;
using CardAppReal.Lib.Models;
namespace CardAppReal.Lib.Entities
{
public class RootCard
{
public List<Card> cards { get; set; }
}
}
If u could help me out I would find it amazing.

I have tested your json.
this is the Model
namespace Test
{
public class Attack
{
public List<string> cost { get; set; }
public string name { get; set; }
public string text { get; set; }
public string damage { get; set; }
public int convertedEnergyCost { get; set; }
}
public class Weakness
{
public string type { get; set; }
public string value { get; set; }
}
public class Resistance
{
public string type { get; set; }
public string value { get; set; }
}
public class Ability
{
public string name { get; set; }
public string text { get; set; }
public string type { get; set; }
}
public class Card
{
public string id { get; set; }
public string name { get; set; }
public int nationalPokedexNumber { get; set; }
public string imageUrl { get; set; }
public string imageUrlHiRes { get; set; }
public string subtype { get; set; }
public string supertype { get; set; }
public string hp { get; set; }
public List<string> retreatCost { get; set; }
public string number { get; set; }
public string artist { get; set; }
public string rarity { get; set; }
public string series { get; set; }
public string set { get; set; }
public string setCode { get; set; }
public List<string> types { get; set; }
public List<Attack> attacks { get; set; }
public List<Weakness> weaknesses { get; set; }
public List<Resistance> resistances { get; set; }
public string evolvesFrom { get; set; }
public Ability ability { get; set; }
public List<string> text { get; set; }
}
public class RootObject
{
public List<Card> cards { get; set; }
}
}
And this is how I call the Deserialize
RootObject root = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(RootObject.WRONG_JSON);
(NB WRONG_JSON is your json string...)

I'm having some issues handling a JSON array, Here is what I've tried. I have tried also using <List<jsonResponse.RootObect> and get the same result.

The problem was with my class not having the correct properties, it also turns out that the UPS api doesn't send a static type response and it can be different each time.. requiring a new class to deserialize into. I have not found a way to make the class flexible

I deserialize complex JSON (Spotify Playlist) and get root level values but I cannot get branches values. I Google problem, try different options without success but, I assume its silly mistake or lack of knowledge so therefore just ask for help what I am missing?
My classes are:
public class Playlist
{
public string collaborative { get; set; }
public string description { get; set; }
//public <ExternalUrls> external_urls { get; set; } //object
//public List<Followers> followers { get; set; } //object
public string href { get; set; }
public string id { get; set; }
//public List<Image> images { get; set; } //array
public string name { get; set; }
}
public class Tracks
{
public string href { get; set; }
public Item items { get; set; } //object
public string limit { get; set; }
public string next { get; set; }
public string offset { get; set; }
public string previous { get; set; }
public string total { get; set; }
}
And code to deserialize looks like that:
StreamReader responseFromServer = new StreamReader(myWebResponse.GetResponseStream());
var dataResponse = responseFromServer.ReadToEnd();
responseFromServer.Close();
var elements = new JavaScriptSerializer().Deserialize<Playlist>(dataResponse);
RootBuffer.AddRow();
RootBuffer.collaborative = elements.collaborative.ToString();
foreach (Tracks trs in elements.tracks)
{
TracksBuffer.AddRow();
TracksBuffer.href = trs.href.ToString()
}

I genereated the classes using this excellent site: json2csharp.com
And used your existing deserialization code successfully with the following classes. It populated all the data including the child collections (brace yourself, it's a long one):
public class Playlist
{
public bool collaborative { get; set; }

Hope this helps.

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.
