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); } } }} |
