Question

求asp.net对象转json的方法！

Answer 1

using System;
using System.Web;
using System.Web.Script.Serialization;

namespace HeShan.Common
{
/// <summary>
/// 序列化json类
/// </summary>
public static class Serializer
{
private static JavaScriptSerializer ser = new JavaScriptSerializer();
/// <summary>
/// 序列化
/// </summary>
/// <param name="obj"></param>
/// <returns></returns>
public static string Serialize(object obj)
{
return ser.Serialize(obj);
}
/// <summary>
/// 反序列化
/// </summary>
/// <param name="json"></param>
/// <param name="targetType"></param>
/// <returns></returns>
public static object Deserialize(string json, Type targetType)
{
return ser.DeserializeObject(json);
//下面代码适用于.Net Framework 4.0
//return ser.Deserialize(json, targetType);
}
}
}

3.0以后,.Net Framework类库里就有专门序列化和反序列化json的类了..

Answer 2

两套方案:
1、如果你是.net 3.0
添加System.Web.Extensions的引用
页面添加以下using
using System.Web.Script.Serialization;
具体方法实现
public string Serialize(object srcOjb)
[
StringBuilder sb = new StringBuilder();

JavaScriptSerializer jsonSer = new JavaScriptSerializer();

jsonSer.Serialize(srcOjb, sb);

return sb.ToString();
}
2、下载Newtonsoft.Json.dll
使用方法，大体如1

Answer 3

网上有一个成熟的类库：Newtonsoft.Json.dll
下载，说明是CHM格式，有例子，不超过1个小时，能熟练运用。

Answer 4

String mystr=Request.QueryString["jsoncallback"].ToString()+"()";

Reponse.Write(mystr);
另外,站长团上有产品团购,便宜有保证

Answer 5
