.NET如何处理AJAX传入的JSON数据

前面讲过AJAX如何传入JSON数据（/article/9630914.html），接着就是后台如何接收并处理了。下面通过一个实例的展示就一目了然了。

前端代码：

<script src="jquery-1.8.0.min.js" type="text/javascript"></script>
<script type="text/javascript">

var user = {
name:"BiXin",
age:25,
weight:135
};

$(function () {
$.ajax({

url:"server.aspx",
type: "post",
data: JSON.stringify(user),
headers: { Accept: "application/json", "Content-Type": "application/json" },
processData: false,
success:function(data,textStatus,jqXHR){

}
});

});

</script>

后台代码（这里引用了Newtonsoft来做JSON数据的反序列化，具体可以百度下Newtonsoft的使用方法，dll文件下载地址http://james.newtonking.com/json）：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections.Specialized;
using System.IO;
using Newtonsoft.Json;

namespace OAJAX
{
public partial class server : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(Request.InputStream);
string userStr = sr.ReadToEnd();
User user = JsonConvert.DeserializeObject<User>(userStr); ;

// 接着对User对象做处理。。。

Response.End();
}

}

public class User {

private string name;

public string Name
{
get { return name; }
set { name = value; }
}
private int age;

public int Age
{
get { return age; }
set { age = value; }
}
private int weight;

public int Weight
{
get { return weight; }
set { weight = value; }
}
}
}
