I have the following Json: http://pastebin.com/pd62g62w
How can I deserialize "sensors" and turn it into an array/list ?
I'm using Json.NET for the deserialization.
DeviceModel deviceModel = new DeviceModel();
deviceModel = JsonConvert.DeserializeObject<DeviceModel>(json);
My current code:
using System;
using Newtonsoft.Json;
namespace Homecheck.Models {
public class DeviceModel {
public string error { get; set; }
public string errorType { get; set; }
[JsonProperty(PropertyName = "_id")]
public string id { get; set; }
[JsonProperty(PropertyName = "_user")]
public string user { get; set; }
[JsonProperty(PropertyName = "_serial")]
public string serial { get; set; }
}
}
Create a class for sensors objects
public class Sensor {
public bool Active { get; set; }
[JsonProperty(PropertyName = "_description")]
public bool Description { get; set; }
/* and so on */
}
And then add it to your model as IEnumerable<Sensor> property:
public class DeviceModel {
/* existing properties omitted */
public IEnumerable<Sensor> Sensors { get; set; }
}
IEnumerable<Sensor> gives you an interface to go through all elements.
You can also use IList<Sensor> if you want list semantics (add, remove, access by index), or use array Sensor[] if you just want to have access by index.

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; }
}
I have been trying to get this json to deserialize for two days now using RestSharp. I have gone through the RestSharp github site, looked at countless examples, and spent much time here on Stack Overflow to try and find the answer to no avail. My code had previously worked perfectly but the vendor changed their API version and I was forced to do an update to keep using the application for my legal practice. My json is as follows(client info has been removed and replaced with generic info):
{
"data":[
{
"id":1035117666,
"client":
{
"id":905422394,
"name":"client1"
},
"display_number":"11-00012",
"description":"General",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2011-12-14",
"close_date":null,
"billing_method":"hourly"
},
{
"id":1035117768,
"client":
{
"id":905422506,
"name":"client2"
},
"display_number":"12-00037",
"description":"HOA",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2012-08-07",
"close_date":null,
"billing_method":"hourly"
}
],
"meta":
{
"paging":
{
"next":"https://app.goclio.com/api/v4/matters.json?fields=id%2C+client%7Bid%2C+name%7D%2C+display_number%2C+description%2C+practice_area%7Bid%2C+name%7D%2C+status%2C+open_date%2C+close_date%2C+billing_method&limit=2&page_token=BAh7BjoLb2Zmc2V0aQc%3D--b1ea3eba20c8acefbcdfc7868debd1e0ee630c64&status=Open"
},
"records":91
}
}
I built the following schema within my c# code:
public class MatterList
{
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
public class Meta
{
public Paging paging { get; set; }
public int records { get; set; }
}
public class Paging
{
public string previous { get; set; }
public string next { get; set; }
}
[DeserializeAs(Name = "data")]
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
public class PracticeArea
{
public int id { get; set; }
public string name { get; set; }
}
public class Client
{
public int id { get; set; }
public string name { get; set; }
}
When I run the RestSharp deserialize method I am sending the result to an object of type MatterList using the following line of code
MatterList matterList = jsonHandler.Deserialize<MatterList>(response);
I have so far attempted to deserialize without the Meta or Paging POCO classes with the accompanying change to the MatterList class (taking out the Meta property).
I have tried with and without the [DeserializeAs(Name="data")] directive.
I have tried to set the RootElement of the json response prior to deserialization.
I have tried to shorthand the deserialization by combining it with the Execute request code
IRestResponse<MatterList> matterList = client.Execute<MatterList>(request);
I have created a container class called MatterContainer which I placed between MatterList and Matter classes in the schema:
public class MatterList
{
public List<MatterContainer> matters { get; set; }
}
public class MatterContainer
{
public Matter matter { get; set; }
}
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
I know I am getting the json response back from the server correctly so my request is proper and MatterList is not null after deserialization. The problem is that I cannot get the deserialization to actually populate the List matters within the MatterList class.
I have been looking at this off and on for two days and cannot get past this hurdle. If anyone sees what I did wrong I would greatly appreciate the insight, I am at a point where I cannot progress further with my application.
Thanks!
I think your [DeserializeAs(Name = "data")] attribute is in the wrong place. Try putting it in the root class instead:
public class MatterList
{
[DeserializeAs(Name = "data")]
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
alternatively, try renameing that property to data
I have a xml format in following format mentioned below:-
<JobRunnerPluginStaus PluginName="JobRun">
<JobstepStatus>
<JobStatus StepNumber="1" StepStatus="Done"/>
<JobStatus StepNumber="2" StepStatus="Started" />
</JobstepStatus>
</JobRunnerPluginStaus>
I want to get it converted to following class object using Generics and Reflection.
I want to convert the attributes to simple type(PluginName) and the nested property to a list object(JobstepStatus).
public class JobRunnerPluginStaus
{
public List<JobStatus> JobstepStatus { get; set; }
public string PluginName { get; set; }
}
public class JobStatus
{
public int StepNumber { get; set; }
public string StepStatus { get; set; }
}
I mostly use sites like: https://xmltocsharp.azurewebsites.net/
to do the dirty work for me.
Below is how your class hierarchy would look like:
[XmlRoot(ElementName="JobStatus")]
public class JobStatus {
[XmlAttribute(AttributeName="StepNumber")]
public string StepNumber { get; set; }
[XmlAttribute(AttributeName="StepStatus")]
public string StepStatus { get; set; }
}
[XmlRoot(ElementName="JobstepStatus")]
public class JobstepStatus {
[XmlElement(ElementName="JobStatus")]
public List<JobStatus> JobStatus { get; set; }
}
[XmlRoot(ElementName="JobRunnerPluginStaus")]
public class JobRunnerPluginStaus {
[XmlElement(ElementName="JobstepStatus")]
public JobstepStatus JobstepStatus { get; set; }
[XmlAttribute(AttributeName="PluginName")]
public string PluginName { get; set; }
}
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;

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; }
}
You can use this link For your referencehttp://jsonutils.com/.
JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
// Deserialize the response to get an array of CUSTOM Cases
var reportsList = jsSerializer.Deserialize<SfdcObjects.SfdcCollection<SfdcObjects.Assets>>(HttpUtility.UrlDecode(response));
throws an exception:
Error: System.InvalidOperationException: Type 'SalesforceDataQueryComponent.Utils.SfdcObjects+SfdcCollection`1[
[SalesforceDataQueryComponent.Utils.SfdcObjects+Assets, SalesforceDataQueryComponent, Version=1.2.0.0, Culture=neutral]]'
is not supported for deserialization of an array.
I can not figure it out the issue:
Objects:
namespace SalesforceDataQueryComponent.Utils
{
class SfdcObjects
{
// Used for Authentication
public class TokenResponse
{
public string id { get; set; }
public string issued_at { get; set; }
public string refresh_token { get; set; }
public string instance_url { get; set; }
public string signature { get; set; }
public string access_token { get; set; }
}
// All classes shown next are used to parse the HttpGet Response
public class SfdcCollection<T>
{
public bool Done { get; set; }
public int Size { get; set; }
public string NextRecordsUrl { get; set; }
public List<T> Records { get; set; }
}
public class SfdcAttributes
{
public string Type { get; set; }
public string Url { get; set; }
}
public class Accounts : Account
{
public SfdcAttributes Attributes { get; set; }
}
public class Assets : Asset
{
public SfdcAttributes Attributes { get; set; }
}
public class CustomAssets : Assets
{
public string StringInstallDate { get; set; }
}
public class Users : User
{
public SfdcAttributes Attributes { get; set; }
}
public class CustomCase : Case
{
public string StringCreatedDate { get; set; }
}
public class CustomCases : CustomCase
{
public SfdcAttributes Attributes { get; set; }
}
}
}
You do not include your response JSON in your question, however from the error message, your problem must be that the root JSON container in your response is an array. A JSON array, according to the JSON standard, looks like this:
[value1, value2, ..., valueN]
JSON serializers map types that implement ICollection or IEnumerable from and to JSON arrays.
Your root object SfdcCollection<T>, however, is NOT a collection or enumerable, despite its name. Instead it's a non-enumerable generic POCO:
public class SfdcCollection<T> // No IEnumerable<T>
{
public bool Done { get; set; }
public int Size { get; set; }
public string NextRecordsUrl { get; set; }
public List<T> Records { get; set; }
}
Thus a serializer will map this to a JSON object (which is a set of key/value pairs and looks like {"name1" : value1, "name2" : value2, ..., "nameN" : valueN }) instead of an array.
You need to update your data model to the JSON you are actually receiving. Try uploading your JSON to http://json2csharp.com/, it will automatically generate classes for you.
If you must use the classes in your question, you could ask another question about how to map the JSON you are actually receiving onto your required classes, using your desired serializer (e.g. Json.NET, DataContractJsonSerializer, JavaScriptSerializer, or etc.)
