将 JSON 对象映射到 C# class 属性数组

Question

JSON

{
"SoftHoldIDs": 444,
"AppliedUsages": [
    {
        "SoftHoldID": 444,
        "UsageYearID": 223232,
        "DaysApplied": 0,
        "PointsApplied": 1
    }
],
"Guests": [
    1,
    2
]

} 在上面 JSON SoftholdIDs 是整数，AppliedUsages 是 class 数组属性 in C# Model

问题是——我们如何将 JSON 映射到 class 属性。 Class代码

  public class ReservationDraftRequestDto
{

    public int SoftHoldIDs { get; set; }
    public int[] Guests { get; set; }
    public AppliedUsage[] AppliedUsages { get; set; }

}


public class AppliedUsage
{
    public int SoftHoldID { get; set; }
    public int UsageYearID { get; set; }
    public int DaysApplied { get; set; }
    public int PointsApplied { get; set; }
}

尝试了以下映射代码

ReservationDraftRequestDto reservationDto = null;

        dynamic data  = await reservationDraftRequestDto.Content.ReadAsAsync<object>();
                    reservationDto = JsonConvert.DeserializeObject<ReservationDraftRequestDto>(data.ToString());

Answer 1

你需要改变

dynamic data  = await reservationDraftRequestDto.Content.ReadAsAsync<object>();

到

string data = await reservationDraftRequestDto.Content.ReadAsStringAsync();

这会将您的回复读取为字符串

然后做

reservationDto = JsonConvert.DeserializeObject<ReservationDraftRequestDto>(data);

Answer 2

这项工作

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp2
{
         class Program
    {
        static void Main(string[] args)
        {
            string json = @"{""SoftHoldIDs"": 444,""AppliedUsages"": [    {""SoftHoldID"": 444,""UsageYearID"": 223232,""DaysApplied"": 0,""PointsApplied"": 1}],""Guests"": [ 1, 2]}";

            Rootobject reservationDto = JsonConvert.DeserializeObject<Rootobject>(json.ToString());

            Debug.WriteLine(reservationDto.SoftHoldIDs);
            foreach (var guest in reservationDto.Guests)
            {

                Debug.WriteLine(guest);
            }

        }
    }

    public class Rootobject
    {
        public int SoftHoldIDs { get; set; }
        public Appliedusage[] AppliedUsages { get; set; }
        public int[] Guests { get; set; }
    }

    public class Appliedusage
    {
        public int SoftHoldID { get; set; }
        public int UsageYearID { get; set; }
        public int DaysApplied { get; set; }
        public int PointsApplied { get; set; }
    }


}

首先使用 visualstudio 创建 class 将 json 复制为 class。接下来你在 json 响应中有双引号所以处理它。 Json.NET: Deserilization with Double Quotes
