下面引入一个很简单的例子

设置页面test_cookies_set.aspx代码如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test_cookies_set.aspx.cs" Inherits="test_cookies_set" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:button ID="Button1" runat="server" text="Button" οnclick="Unnamed1_Click" />

<a href="test_cookies_read.aspx">跳转测试cookies设置</a>
    </div>
    </form>
</body>
</html>

test_cookies_set.aspx.cs代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class test_cookies_set : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Unnamed1_Click(object sender, EventArgs e)
    {
        HttpCookie ck_person = new HttpCookie("person");//主键为person
        ck_person.Value = "小王";//值为小王
        ck_person.Expires = DateTime.Now.AddDays(1);//过期时间设置
        Response.Cookies.Add(ck_person);//将cookies写入硬盘
    }
}

test_cookies_read.aspx.cs代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class test_cookies_read : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.Cookies["person"] != null) {//如果主键为person的cookie不为空，那么

            string _value = Request.Cookies["person"].Value;//那么获取它的value
            Response.Write(_value);
        }
    }
}
