Nested JSON parsing in C# - c#

Hi I have a simple nested json and am trying to parse it with Javascriptserializer(). I created a class with properties and one more class for another nested data. But am not able to access full properties
I have tried the below code
This works well and below is my class where am saving this content
when i do

Please try below code.
I have tried with Newtonsoft.Json
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
var jsonData ="{\"Command\":\"te\",\"Data\":{\"Image\":\"/6D/ogARAP8\",\"Imagetype\":\"FLS\",\"Imageformat\":\"bmp\",\"MissingFingers\":[\"FLIF\",\"FLMF\"]}}";
var jsonRootObject = JsonConvert.DeserializeObject<RootObject>(jsonData);
Console.WriteLine(jsonRootObject.Data.MissingFingers[0]);
Console.WriteLine(jsonRootObject.Data.Imagetype);
Console.WriteLine(jsonRootObject.Data.Image);
}
public class Data
{
public string Image { get; set; }
public string Imagetype { get; set; }
public string Imageformat { get; set; }
public List<string> MissingFingers { get; set; }
}
public class RootObject
{
public string Command { get; set; }
public Data Data { get; set; }
}
}

Deserialize JSON to Nested Model

I have a model like below:
public class YourInformationInputModel
{
public YourInformationInputModel()
{
PrimaryBuyerInformation = new PrimaryBuyerInformationInputModel();
}
public PrimaryBuyerInformationInputModel PrimaryBuyerInformation { get; set; }
public bool TermsCondition { get; set; }
}
PrimaryBuyerInputModel like below:
public class PrimaryBuyerInformationInputModel
{
[Required]
public string BuyerFirstName { get; set; }
public string BuyerMiddleInitial { get; set; }
[Required]
public string BuyerLastName { get; set; }
}
and when I am submitting my form then I am getting JSON like below:
{
"PrimaryBuyerInformation.BuyerFirstName": "Sunil",
"PrimaryBuyerInformation.BuyerMiddleInitial": "",
"PrimaryBuyerInformation.BuyerLastName": "Choudhary",
"TermsCondition": "true"
}
When I am trying to deserialize this json the TermsCondition property successfully done, but the property of PrimaryBuyerInformation is not mapped.
var myObject = JsonConvert.DeserializeObject<YourInformationInputModel>(json);
Any idea how to do that ?
Kindly take a cue from the code below, i tested it and you should be able to get your value as request. This solves the issue of you trying to access the property you have mapped in a dot property name format.
Instead your object should be nested in a curly brace showing that the other property belongs to PrimaryBuyerInformationInputModel which is another object entirely.
Best Regards,
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
var json = #"{'PrimaryBuyerInformation': {'buyerFirstName': 'Sunil','buyerMiddleInitial': '','buyerLastName': 'Choudhary'},'termsCondition': false}";
var obj = JsonConvert.DeserializeObject<YourInformationInputModel>(json);
Console.WriteLine(obj.PrimaryBuyerInformation.BuyerFirstName);
}
}
public class YourInformationInputModel
{
public YourInformationInputModel()
{
PrimaryBuyerInformation = new PrimaryBuyerInformationInputModel();
}
public PrimaryBuyerInformationInputModel PrimaryBuyerInformation { get; set; }
public bool TermsCondition { get; set; }
}
public class PrimaryBuyerInformationInputModel
{
public string BuyerFirstName { get; set; }
public string BuyerMiddleInitial { get; set; }
public string BuyerLastName { get; set; }
}

Class with Collection Properties are not binding properly when posted as XML to ASP.Net Core 3.1 Web API

I'm trying to post my data as XML to my asp.net core 3.1 web api. However Collection properties are not getting binded in my model.
Here is my class,
public class Test
{
public int Usrno { get; set; }
public string PCname { get; set; }
public List<Best> Best { get; set; }
}
public class Best
{
public string Hello { get; set; }
public Worst[] Worst { get; set; }
}
public class Worst
{
public int Ko { get; set; }
public Win[] Win { get; set; }
}
public class Win
{
public string Kiss { get; set; }
}
Here is my POST end point,
[HttpPost]
[Consumes("application/xml")]
[Produces("application/xml")]
public IActionResult Create([FromBody]Test data)
{
return Created("", data);
}
Here is my XML input,
<?xml version="1.0" encoding="UTF-8"?>
<Test>
<Usrno>0</Usrno>
<PCname>string</PCname>
<Best>
<Hello>string</Hello>
<Worst>
<Ko>0</Ko>
<Win>
<Kiss>string</Kiss>
</Win>
</Worst>
</Best>
</Test>
Here is the screen print of the POST method in API,
Here is my ConfigureServices in Startup.cs,
services
.AddControllers()
.AddJsonOptions(options => { options.JsonSerializerOptions.PropertyNamingPolicy = null; })
.AddXmlSerializerFormatters()
.AddXmlDataContractSerializerFormatters();
I couldn't figure out what I'm missing. Please assist
Try using a XmlElementAttribute on Best element.
XmlElement attribute indicates that a public field or property represents an XML element when the XmlSerializer serializes or deserializes the object that contains it.
C#
public class Test
{
public int Usrno { get; set; }
public string PCname { get; set; }
[XmlElement("Best")]
public List<Best> Best { get; set; }
}
The MVC's XmlSerializerInputFormatter calls XmlSerializer to deserialize the body of the request and the formetter uses this attribute to mark XML elements.
An array or List in xml serialization expects two tags like "Names" and "Name". You only have one tag so you need to add the attribute XmlElement. This issue occurs in multiple places in your classes. I fixed all the issue. See classes below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XmlReader reader = XmlReader.Create(FILENAME);
XmlSerializer serializer = new XmlSerializer(typeof(Test));
Test test = (Test)serializer.Deserialize(reader);
}
}
public class Test
{
public int Usrno { get; set; }
public string PCname { get; set; }
[XmlElement("Best")]
public List<Best> Best { get; set; }
}
public class Best
{
public string Hello { get; set; }
[XmlElement("Worst")]
public Worst[] Worst { get; set; }
}
public class Worst
{
public int Ko { get; set; }
[XmlElement("Win")]
public Win[] Win { get; set; }
}
public class Win
{
public string Kiss { get; set; }
}
}

Issues Deserializing Xml in C#

I'm following the tutorial given here for deserializing an embedded xml document.
My Xml doc:
<?xml version="1.0" encoding="utf-8" ?>
<ArrayOfAgency xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<DbAgencyDefinition>
<Name>RTD</Name>
<Country>USA</Country>
<City>Denver</City>
<State>CO</State>
<GtfsZipUrlDirectory>http://www.address.com/etc/</GtfsZipUrlDirectory>
<GtfsZipUrlFileName>file_name.zip</GtfsZipUrlFileName>
</DbAgencyDefinition>
</ArrayOfAgency>
My class I'm deserializing to:
public class DbAgencyDefinition
{
public string Name { get; set; }
public string City { get; set; }
public string Country { get; set; }
public string GtfsZipUrlDirectory { get; set; }
public string GtfsZipUrlFileName { get; set; }
public string State { get; set; }
}
The code that's trying to deserialize the XML to a list of DbAgencyDefinition:
var assembly = IntrospectionExtensions.GetTypeInfo(typeof(DbAgencyDefinition)).Assembly;
Stream stream = assembly.GetManifestResourceStream("MyNamespace.Resources.xml.AgencyDefinitions.xml");
var agencies = new List<DbAgencyDefinition>();
using (var reader = new StreamReader(stream))
{
var serializer = new XmlSerializer(typeof(List<DbAgencyDefinition>));
agencies = (List<DbAgencyDefinition>)serializer.Deserialize(reader);
}
The error I'm getting is:
System.Exception: There is an error in XML document. <ArrayOfAgency xmlns=''> was not expected
I've tried a million things with the XML, marking the class as Serializable, and it always returns this error. I looked at the code samples that the tutorial gives and I can't figure out why I'm getting this error.
VS for Windows, and maybe on Mac as well, has a special tool that will convert copied Xml into autogenerated classes. Now, it's not perfect but if you take your Xml file it generates a couple of classes similar to this:
public class ArrayOfAgency
{
public ArrayOfAgencyDbAgencyDefinition DbAgencyDefinition { get; set; }
}
public class ArrayOfAgencyDbAgencyDefinition
{
public string Name { get; set; }
public string Country { get; set; }
public string City { get; set; }
public string State { get; set; }
public string GtfsZipUrlDirectory { get; set; }
public string GtfsZipUrlFileName { get; set; }
}
As you might notice ArrayOfAgency is determined as a class holding a DbAgencyDefinition, which is why it's throwing an error while trying to deserialize it directly into a List<DbAgencyDefinition>. The type and what the serializer is expecting are not quite the same.
var serializer = new XmlSerializer(typeof(ArrayOfAgency));
var agencies = ((ArrayOfAgency)serializer.Deserialize(reader)).DbAgencyDefinition;
Also, as I mentioned the auto-generation may not be perfect because ArrayOfAgency may need to hold an array instead of a direct class if there can be more than one DbAgencyDefinition possible in Xml.
public class ArrayOfAgency
{
public ArrayOfAgencyDbAgencyDefinition[] DbAgencyDefinition { get; set; }
}
If you need more help or info on Xml Serialization check out the docs.
Try following :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
namespace ConsoleApplication120
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
using (var reader = new StreamReader(FILENAME, Encoding.UTF8))
{
var serializer = new XmlSerializer(typeof(ArrayOfAgency));
ArrayOfAgency agencies = (ArrayOfAgency)serializer.Deserialize(reader);
}
}
}
public class ArrayOfAgency
{
public DbAgencyDefinition DbAgencyDefinition { get; set; }
}
public class DbAgencyDefinition
{
public string Name { get; set; }
public string City { get; set; }
public string Country { get; set; }
public string GtfsZipUrlDirectory { get; set; }
public string GtfsZipUrlFileName { get; set; }
public string State { get; set; }
}
}

Reading from JSON API with C# in SSIS

I want to read some data from a JSON API in SSIS and write it to a table in SQL Server. I've solved the task using a 3rd party, but the solution isn't that elegant, so now I'm trying to script it myself in Visual Studio using SSIS's script component.
I've researched around the web for solutions, and ended with this result. So far, I'm fairly confident about what is going on, but I lack the final direction for this. I know I need to somehow map the output to the columns I've created in SSIS.
I guess I have to do something around CreateNewOutputRows(), but I'm not sure what. Can someone please help me out on this? Also, since this is more or less my first ever c# script, I would also appreciate it, if there's a way easier solution OR if it is in some way inappropriate etc.
First of all, the output from the API looks like this (API documentation here):
"data":[
{
"created_at":"2016-03-12 09:45:00",
"created_at_unix":1457772300,
"shop_name":"DK - Some name",
"location_id":1111,
"custom_location_id":"2222",
"custom_shop_id":"2222",
"shop_id":3333,
"count_in":"1",
"count_out":"1",
"timekey":3
}
The script I've got so far is
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.Linq;
using System.Net;
using System.Collections.Generic;
using Newtonsoft.Json;
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
public static void Main()
{
//Test api
var url = "https://login.vemcount.com/api/fetch_data/?data={"api_key":"xxxxxxx","type":"company_id","id":"10","date_from":"2019-01-01 00:00","interval":"15min", "group_by":"shop_id"}";
var json = new WebClient().DownloadString(url);
var root = JsonConvert.DeserializeObject<RootObject>(json);
//Printing last record
Console.WriteLine(root.data.Last().created_at);
}
public class data
{
public string created_at { get; set; }
public int created_at_unix { get; set; }
public string shop_name { get; set; }
public int location_id { get; set; }
public string custom_location_id { get; set; }
public string custom_shop_id { get; set; }
public int shop_id { get; set; }
public string count_in { get; set; }
public string count_out { get; set; }
public int timekey { get; set; }
}
public class RootObject
{
public List<data> data { get; set; }
}
public override void CreateNewOutputRows()
{
}
}
You'll put all that code in CreateNewOutputRows().
First you have to manually add all the columns to the script component. In the example here I only added 2 columns:
The code goes in CreateNewOutPutRows(). I don't have Newtonsoft, just using the JavaScriptSerializer here to show a working example so you can see how to hook it up:
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.Web.Script.Serialization;
using System.Collections.Generic;
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
public override void CreateNewOutputRows()
{
string json = #"{""data"":[{""created_at"":""2016-03-12 09:45:00"",""created_at_unix"":1457772300,""shop_name"":""DK - Some name"",""location_id"":1111,""custom_location_id"":""2222"",""custom_shop_id"":""2222"",""shop_id"":3333,""count_in"":""1"",""count_out"":""1"",""timekey"":3},{""created_at"":""2016-03-12 09:45:00"",""created_at_unix"":1457772300,""shop_name"":""test2"",""location_id"":1111,""custom_location_id"":""2222"",""custom_shop_id"":""2222"",""shop_id"":3333,""count_in"":""1"",""count_out"":""1"",""timekey"":3}]}";
RootObject Test = new JavaScriptSerializer().Deserialize<RootObject>(json);
/*
* This is where data gets added to the output buffer.
* After AddRow() you are basically mapping the column you manually added(on the left) to the data(on the right).
* using a foreach loop to loop through the deserialize json
*/
foreach (var item in Test.data)
{
Output0Buffer.AddRow();
Output0Buffer.createdat = item.created_at;
Output0Buffer.shopname = item.shop_name;
}
}
public class RootObject
{
public List<data> data { get; set; }
}
public class data
{
public string created_at { get; set; }
public int created_at_unix { get; set; }
public string shop_name { get; set; }
public int location_id { get; set; }
public string custom_location_id { get; set; }
public string custom_shop_id { get; set; }
public int shop_id { get; set; }
public string count_in { get; set; }
public string count_out { get; set; }
public int timekey { get; set; }
}
}
Then in this example, just using a record set destination and enabled data viewer so you can see the individuals rows come back out:

Convert JSON Object to C# Object

I have a json object and I am trying to convert it to my c# object. Here is my JSON:
{"GuvenlikNoktaArray": {"GuvenlikNoktası": [{"Id": 1,"GuvenlikNoktası1":"SANTIYE","KartNo":"000001889174217","Sira": 1},{"Id": 2,"GuvenlikNoktası1":"INSAAT","KartNo":"000000803567858","Sira": 2},{"Id": 3,"GuvenlikNoktası1":"ÇALISMA","KartNo":"000003417926233","Sira": 3},{"Id": 4,"GuvenlikNoktası1":"GÜVENLIK","KartNo":"000001888909897","Sira": 4}]}}
And my c# class:
public partial class GuvenlikNoktası
{
public GuvenlikNoktası()
{
this.GüvenlikNoktasıOlay = new HashSet<GüvenlikNoktasıOlay>();
this.PanikButonuAlarmlari = new HashSet<PanikButonuAlarmlari>();
}
public int Id { get; set; }
public string GuvenlikNoktası1 { get; set; }
public string KartNo { get; set; }
public string Sira { get; set; }
public virtual ICollection<GüvenlikNoktasıOlay> GüvenlikNoktasıOlay { get; set; }
public virtual ICollection<PanikButonuAlarmlari> PanikButonuAlarmlari { get; set; }
}
And last, my convert try:
public void AddIstasyon(string json_string)
{
GuvenlikNoktası result = new JavaScriptSerializer().Deserialize<GuvenlikNoktası>(json_string);
}
I don't get any errors but when I debuged, I see that all attributes inside 'result' are null. It seems like an empty object. How can I get a correct 'GuvenlikNoktası' object ? (Btw I am pretty sure I am getting the json object correctly).
If you must keep this JSON structure as-is you may use JObject to navigate inside your JSON properties until you reach your target objects to deserizlize. Please can you try the code below;
PS: This code uses Newtonsoft.Json;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SO_39847703

{
string json = "{\"GuvenlikNoktaArray\": {\"GuvenlikNoktası\": [{\"Id\": 1,\"GuvenlikNoktası1\":\"SANTIYE\",\"KartNo\":\"000001889174217\",\"Sira\": 1},{\"Id\": 2,\"GuvenlikNoktası1\":\"INSAAT\",\"KartNo\":\"000000803567858\",\"Sira\": 2},{\"Id\": 3,\"GuvenlikNoktası1\":\"ÇALISMA\",\"KartNo\":\"000003417926233\",\"Sira\": 3},{\"Id\": 4,\"GuvenlikNoktası1\":\"GÜVENLIK\",\"KartNo\":\"000001888909897\",\"Sira\": 4}]}}";
AddIstasyon(json);
}
public static void AddIstasyon(string json_string)
{
dynamic jsonObject = JObject.Parse(json_string);
string jsonToDeserializeStrongType = jsonObject["GuvenlikNoktaArray"]["GuvenlikNoktası"].ToString();
List<GuvenlikNoktası> result = JsonConvert.DeserializeObject<List<GuvenlikNoktası>>(jsonToDeserializeStrongType); ;
}
}
public partial class GuvenlikNoktası
{
public GuvenlikNoktası()
{
this.GüvenlikNoktasıOlay = new HashSet<GüvenlikNoktasıOlay>();
this.PanikButonuAlarmlari = new HashSet<PanikButonuAlarmlari>();
}
public int Id { get; set; }
public string GuvenlikNoktası1 { get; set; }
public string KartNo { get; set; }
public string Sira { get; set; }
public virtual ICollection<GüvenlikNoktasıOlay> GüvenlikNoktasıOlay { get; set; }
public virtual ICollection<PanikButonuAlarmlari> PanikButonuAlarmlari { get; set; }
}
public class GüvenlikNoktasıOlay
{
}
public class PanikButonuAlarmlari
{
}
}
Hope this helps
Your JSON data and your class definition do not fit together. Therefore the default values (NULL) are provided by the serializer.
In order to deserialize the given JSON data you need a class structure like:
public class Root
{
public LevelOne GuvenlikNoktaArray {get; set;}
}
public class LevelOne {
public IEnumerable<GuvenlikNoktası> GuvenlikNoktası {get; set;}
}
You can use this class.
public class GuvenlikNoktası
{
public int Id { get; set; }
public string GuvenlikNoktası1 { get; set; }
public string KartNo { get; set; }
public int Sira { get; set; }
}
public class GuvenlikNoktaArray
{
public IList<GuvenlikNoktası> GuvenlikNoktası { get; set; }
}
public class Example
{
public GuvenlikNoktaArray GuvenlikNoktaArray { get; set; }
}
