Pars json file in ASP.NET C#

Question

i have a .json file that i want to pars it and show items in page. i created 3 class called : bultan_details bultan_new bultan_tele and this codes for parsing it :

using (StreamReader r = new StreamReader(filePath))
                    {
                        var json = r.ReadToEnd();
                        var result = JsonConvert.DeserializeObject<Bultan>(json);

                        //var bultanDetails = result.Bultan_Details;
                        var news = result.BultanNews;
                        var telegram = result.BultanTelegram;
                        //Response.Write(bultanDetails.bultan_title + "<br/>");
                        foreach (var item in news)
                        {
                            Response.Write(item.description + "<br/><br/><br/>");
                        }
                        foreach (var tl in telegram)
                        {
                            Response.Write(tl.text + "<br/><br/><br/><br/>");
                        }
                    }

this is my Bultan class

public class Bultan
    {
        public bultan_details Bultan_Details { get; set; }
        public List<Bultan_New> BultanNews { get; set; }
        public List<Bultan_Tele> BultanTelegram { get; set; }
    }

but i get this error after running project :

(e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path 'bultan_details', line 1, position 19.

and this is my json file content :

Your bultan_details is the same array in json as bultan_news and bultan_tele, you have to define it as a collection in dto class too:

public class Bultan
{
    public List<bultan_details> Bultan_Details { get; set; }
    public List<Bultan_New> BultanNews { get; set; }
    public List<Bultan_Tele> BultanTelegram { get; set; }
}

I'd suggest using jsonutils.com to create the object class from a JSON file.

Then id use Newtonsoft.json which you can find in the NuGet Package Manager. And the code below works fine for me -

Bultan data = new Bultan();

var file = Path.Combine(@"FILE PATH");
if (File.Exists(file))
{
    data = JsonConvert.DeserializeObject<Bultan>(File.ReadAllText(file));
}

i suggest you to create a new object serialize it and merge it with your input file. So you will see differences..
