如何解析c#中的JSON对象

Question

我得到以下JSON数据

[{"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"}]

，试图使用Json解析。Net使用强类型

这是我的属性类

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; }
    }

，这里我试图访问数据，我得到异常

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.

我的控制器代码看起来像

 public void Test(string Name, object modeldata)
        {
            var obj = JsonConvert.DeserializeObject<testclass>(Name);
        }

你知道如何在c#中解决这个问题吗

Answer 1

你的Json字符串看起来有序列化数组对象，因为它包含[ ]。这意味着你有一个Json字符串，它是在数组对象序列化后形成的。所以你需要反序列化成数组对象，试试this

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

Answer 2

你有TestClass的数组。所以应该是这样的。

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

为什么你使用JSonConvert ?在MVC3中，你可以这样做

return Json(yourmodel,JsonRequestBehavior.AllowGet);

Answer 3

json对象是这样的

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

我猜应该是这样的

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