C#中操作单个cookie和cookie字典

单个cookie和cookie字典在浏览器中的存储格式如下：

可以看到，单个cookie是以单一键值对的方式存储的，而cookie字典的值包含多个键值对，这些键值对之间以&符号拼接。
cookie字典用于用一个cookie保存多个值的情况。

下面是单个cookie和cookie字典的操作示例：
1、单个cookie

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

        <div>

            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

            <br />

            <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="设置单个cookie" />

            <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="获取单个cookie" />

            <asp:Button ID="Button3" runat="server" OnClick="Button3_Click" Text="修改单个cookie" />

        </div>

    </form>

</body>

</html>

.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace WebApplication1

{

    public partial class CookieSingle : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            HttpCookie cookie = new HttpCookie("xfk_sid")

            {

                Value = "xfk11111111",

                Expires = DateTime.Now.AddDays(1)

            };

            Response.Cookies.Add(cookie);

        }

        protected void Button2_Click(object sender, EventArgs e)

        {

            var objCookie = Request.Cookies["xfk_sid"];

            if (objCookie != null)

            {

                this.Label1.Text += objCookie.Value + "----";

            }

        }

        protected void Button3_Click(object sender, EventArgs e)

        {

            HttpCookie c1 = Request.Cookies["xfk_sid"];

            c1.Value = "after1111111111";

            Response.Cookies.Add(c1);

        }

    }

}

2、cookie字典

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

            <br />

            <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="设置cookie字典" />

            <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="获取cookie字典" />

            <asp:Button ID="Button3" runat="server" OnClick="Button3_Click" Text="修改cookie字典" />

        </div>

    </form>

</body>

</html>

.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace WebApplication1

{

    public partial class CookieDict : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            HttpCookie cookie = new HttpCookie("xfk_sidDict");

            cookie.Values.Add("s1", "ssssssssss");

            cookie.Values.Add("s2", "iiiiiiiii");

            cookie.Values.Add("s3", "ddddddddddd");

            Response.Cookies.Add(cookie);

        }

        protected void Button2_Click(object sender, EventArgs e)

        {

            HttpCookie cookie = Request.Cookies["xfk_sidDict"];

            if (cookie != null && cookie.HasKeys) {

                foreach (string item in cookie.Values)

                {

                    this.Label1.Text += "---" + cookie.Values[item];

                }

            }

        }

        protected void Button3_Click(object sender, EventArgs e)

        {

             HttpCookie cookie = Request.Cookies["xfk_sidDict"];

             if (cookie != null && cookie.HasKeys) {

                 cookie.Values.Set("s1", "hahahahahah");

                 cookie.Values.Set("s3", "heiheiheiheihi");

                 Response.Cookies.Add(cookie);

             }

        }

    }

}
