Question

请问.net后台如何解析json数据

后台代码：
if (!IsPostBack)
{
string jsonArray = Request["jsonArray"].ToString();
}

jsonArray 为：[{\"ID\":\"1\",\"Name\":\"2\",\"PWD\":\"2\",\"IsDelete\":\"True\",\"EntryDate\":\"2010-1-1 0:00:00\"},{\"ID\":\"2\",\"Name\":\"3
\",\"PWD\":\"3\",\"IsDelete\":\"True\",\"EntryDate\":\"2011-1-1 0:00:00\"}]

Answer 1

using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

public partial class JsonTest : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string jsonArray = Request["jsonArray"].ToString();
JavaScriptSerializer json = new JavaScriptSerializer();
List<User> list = json.Deserialize(jsonArray, typeof(List<User>)) as List<User>;

if (list != null && list.Count > 0)
{
foreach (var item in list)
{
Response.Write(item.ID + " " + item.IsDelete + " " + item.EntryDate);
}
}
}
}
}

[Serializable]
class User
{
public int ID { get; set; }
public string Name { get; set; }
public string PWD { get; set; }
public bool IsDelete { get; set; }
public DateTime EntryDate { get; set; }
}

Answer 2

//using Newtonsoft.Json;

List<user> u = JsonConvert.DeserializeObject<List<user>>(json);

//public class user
//{
// public string ID{get;set;}
// public string Name{get;set;}
// public string PWD{get;set;}
// public string IsDelete{get;set;}
// public DateTime EntryDate {get;set;}
//}

Answer 3

Newtonsoft.Json.dll

好像linq也可以
