c# .net反序列化JSON

我试图在我的对象中反序列化JSON: 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
public class FormData
{
    public string audience { get; set; }
    public Calendar[] calendar { get; set; }
    public FormData()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public class Calendar
    {
        public Quarter quarter { get; set; }
    }
    public class Quarter
    {
        public int qtrNumber { get; set; }
        public string qtrString { get; set; }
        public int[] qtrTools { get; set; }
        public int qtrYear { get; set; }
    }
}

这是我的处理器:

<%@ WebHandler Language="C#" Class="ToolHandler" %>
using System;
using System.Web;
using System.Web.Script.Serialization;
using System.Text;
using System.IO;

public class ToolHandler : IHttpHandler {
    public void ProcessRequest(HttpContext context)
    {
        HttpRequest Request = context.Request;
        HttpResponse Response = context.Response;
        JavaScriptSerializer serializer = new JavaScriptSerializer();
        Response.ContentType = "text/plain";
        try
        {
            string strJson = new StreamReader(Request.InputStream).ReadToEnd();
            //deserialize the object
            FormData formData = serializer.Deserialize<FormData>(strJson);
            if (formData != null)
            {
                Response.Write("Success!!");
            }
            else
            {
                Response.Write("No Data");
            }
        }
        catch (Exception ex)
        {
            Response.Write("Error :" + ex.Message);
        }
    }
    public bool IsReusable {
        get {
            return false;
        }
    }
}
JSON: 

{
    "audience": "8",
    "calendar": [
        {
            "qtrNumber": 1,
            "qtrYear": 2016,
            "qtrString": "1st Quarter",
            "qtrTools": [
                "3",
                "4"
            ]
        },
        {
            "qtrNumber": 2,
            "qtrYear": 2016,
            "qtrString": "2nd Quarter",
            "qtrTools": []
        },
        {
            "qtrNumber": 3,
            "qtrYear": 2016,
            "qtrString": "3rd Quarter",
            "qtrTools": []
        },
        {
            "qtrNumber": 4,
            "qtrYear": 2016,
            "qtrString": "4th Quarter",
            "qtrTools": []
        }
    ]
}

执行完这行后我看到的:

FormData formData = serializer.Deserialize<FormData>(strJson);

formData对象有适当的受众和日历与4个元素的数组，但所有日历[]。四分之一对象为空。

c# .net反序列化JSON

Calendar类在JSON中没有嵌套Quarter属性。你可以"unnest"嵌套的属性，一切都应该正常工作:

public class FormData
{
    public string audience { get; set; }
    public Calendar[] calendar { get; set; }
    public FormData()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public class Calendar
    {
        public int qtrNumber { get; set; }
        public string qtrString { get; set; }
        public int[] qtrTools { get; set; }
        public int qtrYear { get; set; }
    }
}

没有"qtr"属性在calendar上，它们在Quarter上。JSON必须是:

{
    "audience": "8",
    "calendar": [ {"Quarter" :
        {
            "qtrNumber": 1,
            "qtrYear": 2016,
            "qtrString": "1st Quarter",
            "qtrTools": [
                "3",
                "4"
            ]
        }},
        {"Quarter" : { 
            "qtrNumber": 2,
            "qtrYear": 2016,
            "qtrString": "2nd Quarter",
            "qtrTools": []
        }},
        etc...
    ]
}
