Cannot Deserialize JSON Object type requires a JSON array (e.g. [1,2,3]) to deserialize correctly

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.
I'm using JSON.NET
C#:
jsonResponse.RootObject deserializedResponse = JsonConvert.DeserializeObject<jsonResponse.RootObject>(Globals.jsonResponse);

}

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

Trouble using all members in a class. Why can I only use the list?

I have the following class object structure:
public class StatusObj3
{
public int status { get; set; }
public DataObj3 data { get; set; }
}
public class DataObj3
{
public string survey_id { get; set; }
public string date_created { get; set; }
public string date_modified { get; set; }
public int custom_variable_count { get; set; }
public List<Custom_VariablesObj> custom_variables { get; set; }
public int language_id { get; set; }
public int num_responses { get; set; }
public int question_count { get; set; }
public string nickname { get; set; }
public TitleObj title { get; set; }
public List<PagesObj> pages { get; set; }
}
public class Custom_VariablesObj
{
public string variable_label { get; set; }
public string question_id { get; set; }
}
public class TitleObj
{
public bool enabled { get; set; }
public string text { get; set; }
}
public class PagesObj
{
string page_id { get; set; }
string heading { get; set; }
string sub_heading { get; set; }
public List<QuestionObj> questions { get; set; }
}
public class QuestionObj
{
public string question_id { get; set; }
public string heading { get; set; }
public string position { get; set; }
public QuestionTypeObj type { get; set; }
public List<AnswerObj> answers { get; set; }
}
public class QuestionTypeObj
{
public string family { get; set; }
public string subtype { get; set; }
}
public class AnswerObj
{
public string answer_id { get; set; }
public int position { get; set; }
public string text { get; set; }
public string type { get; set; }
public bool visible { get; set; }
public int weight { get; set; }
public bool apply_all_rows { get; set; }
public bool is_answer { get; set; }
public List<ItemsObj> items { get; set; }
}
public class ItemsObj
{
public string answer_id { get; set; }
public int position { get; set; }
public string type { get; set; }
public string text { get; set; }
}
I 've deserialized json into this object via:
var results_SurveyDetails = deserializer.Deserialize<StatusObj3>(json_returned);
I'm trying to loop thru the pages by:
foreach (var page in results_SurveyDetails.data.pages)
However, not all members of page are available to use.
Only the page.questions is there and not page_id, heading and subheading.
What am I doing wrong?

You are missing public on your other properties in class PagesObj.

Calling Multiple SQL Tables In The Same View

I have multiple tables I need to display in a single view. This seems to be a problem because the view only allows for one model definition from what I can tell. I've tried implementing a workaround solution, but have been unsuccessful.
Specifically, I get the error message: "The model item passed into the dictionary is of type 'System.Data.Entity.DbSet1[BillingApp.Models.HEADER_RECORD]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[BillingApp.Models.tbl1join]'."
The View
#model IEnumerable<BillingApp.Models.tbl1join>
#{
ViewBag.Title = "TABLE 01 DISPLAY";
Layout = "../Shared/Layout2.cshtml";
}
#section featured2 {
<html>
<body>
~excluding tables because there are too many fields~
</body></html>
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace BillingApp.Models
{
public class tbl1join
{
public HEADER_RECORD HeaderRecord { get; set; }
public HEADER_EXTENSION_RECORD ExtensionRecord { get; set; }
}
}
The Model Definitions:
HEADER_RECORD.cs

HEADER_EXTENSION_RECORD.cs
namespace BillingApp.Models
{
using System;
using System.Collections.Generic;
public partial class HEADER_EXTENSION_RECORD
{
public int ERID { get; set; }
public string ETABLE_NUMBER { get; set; }
public string ECOMPANY { get; set; }
public string ESTATE_CODE { get; set; }
public string EBILL_CODE { get; set; }
public string ERECORD_TYPE { get; set; }
public string EMASK_EXTENSION_ID { get; set; }
public string OVERPAYMENT_TOLERANCE_PERCENT { get; set; }
public string UNDERPAYMENT_TOLERANCE_PERCENT { get; set; }
}
}
The Controller (BillingController.cs)
public ActionResult HeaderExtensionRecord()
{
{
return View(db.HEADER_EXTENSION_RECORD);
}
}
public ActionResult HeaderRecordTable1()
{
{
return View(db.HEADER_RECORD);
}
}
Update:
Added tbl1join as the return type in the controller, but gives an error saying it's a type being used as a variable.
public ActionResult HeaderRecordTable1()
{
{
return View(IEnumerable<tbl1join>);
}
}

Wrap it into a ViewModel
public class RecordVM
{
public HEADER_RECORD header { get; set; }
public HEADER_EXTENSION_RECORD ext { get; set; }
}
return View(new RecordVM { header = db.HEADER_RECORD, ext = db.HEADER_EXTENSION_RECORD });

The error message indicates that you are passing in the wrong type, you need to query the database and create the suitable model that your view is expecting. It looks like you are trying to pass 2 models to the view using the view model tbl1join.
You could populate the view model as follows for a specified id value:
public ActionResult ViewModelExtension(int id)
{
var viewModel = new tbl1join();
viewModel.HEADER_RECORD = db.HEADER_RECORD.Where(h => h.id == id).SingleOrDefault;
viewModel.HEADER_EXTENSION_RECORD = db.HEADER_EXTENSION_RECORD.Where(h => h.id == id).SingleOrDefault;
return View(viewModel);
}
I would be surprised if there isn't some relationship between the 2 models. If this was specified within your 2 models then the above could be done differently.

JSON Web Request string to parsed data with JSON.NET

I am using .net to call to a webservice then parse it to usable data.
Right now I am experimenting with this call: http://www.reddit.com/r/all.json
Which returns: http://pastebin.com/AbV4yVuC
This is put in to a string, which I called jsontxt.
I am using JSON.NET to parse the information but it doesn't seem to be working. I initially tried to deserialize it as an object and it didn't work as nothing is put in to the variable
Then I tried to deserialize it as a dataset and I'm having no luck again. My error was
An unhandled exception of type 'Newtonsoft.Json.JsonException' occurred in Newtonsoft.Json.dll
MY CODE:
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

{
static void Main(string[] args)
{
using (var webClient = new System.Net.WebClient())
{
var jsontxt = webClient.DownloadString("http://www.reddit.com/r/all.json");
// Console.Write(json);
// -----Deserializing by Object--------------
//MediaEmbed account = JsonConvert.DeserializeObject<MediaEmbed>(jsontxt);
//Console.WriteLine(account.width); //COMES OUT TO NULL
// -----Deserializing by DataSet--------------
DataSet dataSet = JsonConvert.DeserializeObject<DataSet>(jsontxt);
DataTable dataTable = dataSet.Tables["Children"];
Console.WriteLine(dataTable.Rows.Count);
}
}
public class MediaEmbed
{
public string content { get; set; }
public int width { get; set; }
public bool scrolling { get; set; }
public int height { get; set; }
}
.... //rest of classes here for each json which were generated with http://json2csharp.com/
}
}
I'm just trying to make the JSON easily accessible by parsing it.

Using json2charp I generated the following set of classes. Using those you should be able to deserialize the JSON into RootObject using JSON.NET.
var account = JsonConvert.DeserializeObject<RootObject>(jsontxt);
.

You are trying to deserialize a json-string into a dataset-object. But the json-string doesn't have the format of a dataset. So you need to create a class which matches the json or deserialize it into a dictionary or sth. like this.

Have you tried deserialize using the following? Seems to be more robust for me.
using System.Web.Script.Serialization;
...
var x = new JavaScriptSerializer().Deserialize<Obj_type>(jsonstring);
http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer%28v=vs.110%29.aspx
as purplej0kr mentioned you will need to have a .Net model to use for Obj_type (and it will need to match the object you are parsing) or this will not work.
You will need the System.Web.Extensions.dll referenced in your project (right click add reference, dll is usually under 'Assemblies'). Otherwise:
Where can I find the assembly System.Web.Extensions dll?

c# nested classes the type or namespace could not be found

I have a class with nested subclasses:

In my MVC razor view i try to access the data:
#model PostenNorge.Models.JsonObjectModels.listDevicesModel
<b>#Model.messages.message</b>
<br />
<br />
<ul>
#foreach(Device d in Model.devices.device)
{
<li>#d.name - #d.uuid - #d.currentPhoneNumber</li>
}
</ul>
On Device in the foreach i get "The type or namespace name "Device" could not be found".
How can i access the nested class types in my view?

You need to specify the nested name:
#foreach(listDevicesModel.Device d in Model.devices.device)
Or use implicit typing:
#foreach(var d in Model.devices.device)
Personally I'd avoid using nested classes here anyway, unless you really have to. Even if you do really have to, I'd rename the top-level class to follow normal naming conventions, i.e. make it start with a capital letter.
