ASP.NET ashx文件如何客户端提交的JSON字符串转换成JSON对象然后把值读出来？

Posted 2023-04-14

如何把一下JSON读出来(代码详细一点家悬赏)
string Json = "people": [ "firstName": "Brett", "lastName":"McLaughlin", "email": "aaaa" , "firstName":"Jason","lastName":"Hunter", "email": "bbbb", "firstName": "Elliotte", "lastName":"Harold","email": "cccc" ]

using System.Runtime.Serialization.Json;

public class infoObject

public String name get; set;
public String birthday get; set;
public String id get; set;
public String email get; set;

public infoObject()

name = "";
birthday = "";
id = "";
email = "";


public infoObject(String newname, String newbirthday, String newid, String newemail)

name = newname;
birthday = newbirthday;
id = newid;
email = newemail;



public partial class _Default : System.Web.UI.Page

protected void Page_Load(object sender, EventArgs e)

infoObject info = new infoObject("peng","19920412","342423188209121234","[e-mail]");
string szJson;
//将对象转成字符串
DataContractJsonSerializer json = new DataContractJsonSerializer(info.GetType());
using (MemoryStream stream = new MemoryStream())

json.WriteObject(stream, info);//把对象填充到流里(关键）
szJson = Encoding.UTF8.GetString(stream.ToArray());//按指定格式把流编码成字符串
Response.Write( "对象转成字符串:<br>"+szJson+"<br>");


//将字符串转成对象
//infoObject obj = Activator.CreateInstance<infoObject>();
infoObject obj = new infoObject();
using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))

DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
obj=(infoObject)serializer.ReadObject(ms);//将含有字符串的流转成对象

Response.Write("字符串转对象:"+obj.name + "<br>" + obj.birthday + "<br>" + obj.id + "<br>" + obj.email);

参考技术A jsonSerialization,javascriptSerializer自已百度吧.

asp.net 一般处理程序（ashx）如何多次接收上传文件（多文件批量上传）

aspx页面能接受 调试时候能多次调用，而一般处理程序不能

参考技术A Like
this
：
比如前台有3个INPUT：
然后后台：
HttpFileCollection
files
=
HttpContext.Current.Request.Files;
//这个files里面就是你上传文件的集合。遍历即可。
