前台：[切记：每个表单元素，都应该带有name，否则是取不到的。]

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
function test() {
$("#Action").val(1);
var vals = $("#tableForm :input").serialize(); //var vals = $("#form1").serialize();//两种都可以，但后一种会多取__ViewState这个系统hidden
$.post("Default3.aspx", vals, function (data) {
alert("前台取得值：\n" + vals+"\n后台取得值：\n"+data);
});
}
</script>
</head>
<body>
<form id="form1" runat="server">
<table id="tableForm" style="border-collapse:collapse;" cellpadding="5" cellspacing="2" border="1">
<tr><td>姓名:</td><td><input id="Name" name="Name" type="text" value="刘军" /><input id="Action" name="Action" type="hidden" value="0" /></td></tr>
<tr><td>密码:</td><td><input id="Pwd" name="Pwd" type="password" value="123456" /></td></tr>
<tr><td>性别:</td><td>
<input name="Gender" type="radio" checked="checked" value="Male" />男  
<input name="Gender" type="radio" value="Female" />女</td>
</tr>
<tr><td>爱好：</td><td>
<input id="Checkbox1" type="checkbox" checked="checked" name="Hobby" value="1" />足球 
<input id="Checkbox2" type="checkbox" checked="checked" name="Hobby" value="2" />象棋</td>
</tr>
<tr><td>留言：</td><td><textarea id="Note" name="Note" cols="20" rows="2">+ |</textarea></td></tr>
<tr><td>籍贯：</td><td>
<select id="Select1" name="Home" >
<option value="">---请选择---</option>
<option value="湖南" selected="selected">湖南</option>
<option value="湖北">湖北</option>
</select></td>
</tr>
<tr><td colspan="2"><input id="Button1" type="button" value="测试" onclick="test()" /></td></tr>
</table>
</form>
</body>
</html>

后台：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Request.Form["Action"] == "1") {
Ajax();
}
}
private void Ajax()
{
StringBuilder sb = new StringBuilder();
foreach (string s in Request.Form.AllKeys) {
sb.AppendFormat("{0}: {1}\n",s,Request.Form[s] );
}
Response.Write(sb.ToString());
Response.End();
}
}

—————————————— 结果 —————————————

前台取得值：

Name=%E5%88%98+%E5%86%9B&Action=1&Pwd=123456&Gender=Male&Hobby=1&Hobby=2&Note=%2B++%7C&Home=%E6%B9%96%E5%8D%97
后台取得值：
Name: 刘军
