.NET页面如何把JSON类型的值 传给另一个页面

Question

json的值怎么传给另一个页面
另一个页面是JS页面不能做类型转换 

Answer 1

JSON.net有把对象变成{ss:bb}字符串形式的函数吧？

Answer 2

我是这么写的  可是传过去不能用json.aspx文件
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="json.aspx.cs" Inherits="json" %>json.aspx.cs文件using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections.Generic;
using System.Web.Script.Serialization; public partial class json : System.Web.UI.Page
{
    public List<jsondata> jsdata = new List<jsondata>(); 
    protected void Page_Load(object sender, EventArgs e)
    {        for (int i = 1; i < 5; i++)
        {
            jsondata jd = new jsondata();
            jd.id = "num" + i; jd.text = "节点" + i;
            jd.leaf = false; for (int j = 1; j < 3; j++)
            {
                jsondata subjd = new jsondata();
                subjd.id = "sub" + j;
                subjd.text = "子节点" + j;
                subjd.leaf = true;
                jd.children.Add(subjd);
            }
            jsdata.Add(jd);
        }
        context.Response.Write(ToJson(jsdata.ToArray()));//ToArray()在IE里面好像缺了不行    }    public string ToJson(object o)
    {
        //序列化对象为json数据，很重要！
        JavaScriptSerializer j = new JavaScriptSerializer();
        return j.Serialize(o);
    }
}public class jsondata 
 { //定义jsondata类，存放节点数据 
     public string id; 
     public string text; 
     public bool leaf; 
     public List<jsondata> children=new List<jsondata>();//存放子节点 
} 

Answer 3

        context.Response.Write(ToJson(jsdata.ToArray()));//ToArray()在IE里面好像缺了不行这一行调试不通过 改成了
Response.Write(ToJson(jsdata.ToArray()));//ToArray()在IE里面好像缺了不行传过去的是 
[{"id":"num1","text":"节点1","leaf":false,"children":[{"id":"sub1","text":"子节点1","leaf":true,"children":[]},{"id":"sub2","text":"子节点2","leaf":true,"children":[]}]},{"id":"num2","text":"节点2","leaf":false,"children":[{"id":"sub1","text":"子节点1","leaf":true,"children":[]},{"id":"sub2","text":"子节点2","leaf":true,"children":[]}]},{"id":"num3","text":"节点3","leaf":false,"children":[{"id":"sub1","text":"子节点1","leaf":true,"children":[]},{"id":"sub2","text":"子节点2","leaf":true,"children":[]}]},{"id":"num4","text":"节点4","leaf":false,"children":[{"id":"sub1","text":"子节点1","leaf":true,"children":[]},{"id":"sub2","text":"子节点2","leaf":true,"children":[]}]}]这是字符串 还是JSON？

Answer 4

格式是json的。但感觉不是序列化返回后的json吧。序列化返回的json是带有__type开头的啊。

Answer 5

问题发生在序列化时，具体得看看JavaScriptSerializer的实现代码
尤其是JavaScriptSerializer类的Serialize方法，它没有其他重载么

Answer 6

JavaScriptSerializer是微软提供的吧，那你的用法有问题，你应该传一个可序列化（有[Serializable]特性）的对象
