How to parse a JSON object in C #

I get the following JSON data

[{"id":"1","text":"System Admin","target":{"jQuery1710835279177001846":12},"checked":true,"state":"open"},
{"id":"2","text":"HRMS","target":{"jQuery1710835279177001846":34},"checked":false,"state":"open"},
{"id":"3","text":"SDBMS","target":{"jQuery1710835279177001846":42},"checked":false},
{"id":"8","text":"Admin","target":{"jQuery1710835279177001846":43},"checked":false},
{"id":"9","text":"My test Admin","target":{"jQuery1710835279177001846":44},"checked":false,"state":"open"},
{"id":"24","text":"ModuleName","target":{"jQuery1710835279177001846":46},"checked":false,"state":"open"}]

who are trying to parse using Json.Net using a strict type

this is my property class

public class testclass
    {
        public string id { get; set; }
        public string text { get; set; }
        public string @checked { get; set; }
        public string state { get; set; }
        public target jQuery1710835279177001846 { get; set; }

    }
    public class testclass2
    {
        public List<testclass> testclass1 { get; set; }

    }

    public class target
    {
        public string jQuery1710835279177001846 { get; set; }
    }

and here I try to access the data that I get an exception

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'QuexstERP.Web.UI.Areas.SysAdmin.Controllers.testclass' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.

My controller code looks like

 public void Test(string Name, object modeldata)
        {

            var obj = JsonConvert.DeserializeObject<testclass>(Name);

        }

Any idea how to solve this problem in C #

Your Json string looks like a serialized array object because it contains [ ]. This means that you have a Json string that is formed after the array object is serialized. So you need to deserialize the array object, so try this

var obj = JsonConvert.DeserializeObject<List<testclass>>(jsonString);

you have an array of TestClass. so it should be so.

var model= JsonConvert.DeserializeObject<List<testclass>>(Name);

json

{
      "id":"1",
      "text":"System Admin",
      "target":{
         "jQuery1710835279177001846":12
      },
      "checked":true,
      "state":"open"
}

, ,

{
      "id":"1",
      "text":"System Admin",
      "jQuery1710835279177001846":12,
      "checked":true,
      "state":"open"
