将Newtonsoft.Json.Linq.JArray转换为特定对象类型的列表

Question

我有以下类型的变量{Newtonsoft.Json.Linq.JArray}.

properties["Value"] {[
  {
    "Name": "Username",
    "Selected": true
  },
  {
    "Name": "Password",
    "Selected": true
  }

]}

我想做到的是将其转换为List<SelectableEnumItem>那里SelectableEnumItem是以下类型:

public class SelectableEnumItem
    {
        public string Name { get; set; }
        public bool Selected { get; set; }
    }

我对编程很新,我不确定这是否可行.任何有关工作示例的帮助将不胜感激.

Answer 1

只需调用array.ToObject<List<SelectableEnumItem>>()方法.它会返回你需要的东西.

文档:将JSON转换为类型

Answer 2

问题中的示例是一个更简单的情况,其中属性名称在json和代码中完全匹配.如果属性名称不完全匹配,例如json中"first_name": "Mark"的属性和代码中的属性FirstName则使用Select方法,如下所示

List<SelectableEnumItem> items = ((JArray)array).Select(x => new SelectableEnumItem
{
    FirstName = (string)x["first_name"],
    Selected = (bool)x["selected"]
}).ToList();

在我的情况下，API返回值如下所示：

{
  "pageIndex": 1,
  "pageSize": 10,
  "totalCount": 1,
  "totalPageCount": 1,
  "items": [
    {
      "firstName": "Stephen",
      "otherNames": "Ebichondo",
      "phoneNumber": "+254721250736",
      "gender": 0,
      "clientStatus": 0,
      "dateOfBirth": "1979-08-16T00:00:00",
      "nationalID": "21734397",
      "emailAddress": "sebichondo@gmail.com",
      "id": 1,
      "addedDate": "2018-02-02T00:00:00",
      "modifiedDate": "2018-02-02T00:00:00"
    }
  ],
  "hasPreviousPage": false,
  "hasNextPage": false
}

将项目数组转换为客户列表的方法如下所示：

 if (responseMessage.IsSuccessStatusCode)
        {
            var responseData = responseMessage.Content.ReadAsStringAsync().Result;
            JObject result = JObject.Parse(responseData);

            var clientarray = result["items"].Value<JArray>();
            List<Client> clients = clientarray.ToObject<List<Client>>();
            return View(clients);
        }
