如何在C#中反序列化JSON数据 [英] How do I deserialize JSON data in C#

问题描述

您好，有人可以提供适当的方法来反序列化此格式的json数据吗:

[{person:{name:"James", age:26}}, {person:{name:"Mary", age:36}}, {person:{name:"Kofi", age:46}}]

我使用的代码如下:

 WebRequest请求= WebRequest.Create(" );
Web响应响应= request.GetResponse();

字符串 json;

使用( var  sr = 新 StreamReader( response.GetResponseStream()))
{
    json = sr.ReadToEnd();
}


 var  serializer = 新 JavaScriptSerializer();

 var  persons =序列化程序.反序列化< List< auto>>>(json);

 foreach ( var 项目 in 人)
{
    Console.Write("  + item.name + "  + item.age)；
} 

我映射到的类如下:

 公共  class 人
{
  公共 字符串名称{获取; 设置;}
   public   int  age { get ; 集;}
} 

当我运行此代码时，我不断获得名称和年龄属性的空值和空字符串.如果有人可以帮助我，我将不胜感激.

The code i''am using is as below:

WebRequest request = WebRequest.Create("url");
WebResponse response = request.GetResponse();

string json;

using (var sr = new StreamReader(response.GetResponseStream()))
{
    json = sr.ReadToEnd();
}


var serializer = new JavaScriptSerializer();

var persons= serializer.Deserialize<List<auto>>(json);

foreach (var item in persons)
{
    Console.Write("name:" + item.name + " and age: " + item.age);
}

the class I''am mapping to is as below:

public class person
{
  public string name{get;set;}
  public int age{get; set;}
}

I keep getting nulls and empty strings for the name and age properties when I run this code. I will appreciate it a lot if someone can help me out.

You should have googled before posting the question

I had to make call item.person.name and item.person.age in the foreach loop and make sure all properties in the person class were of type string.
