1.Session的小例子

html页面：

<span style="font-size:24px;"><%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Seession.aspx.cs" Inherits="Session实验.Seession" %><!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="Label2" runat="server" Text="label2"></asp:Label>        </div>        <p>            <asp:Label ID="Label1" runat="server" Text="Label1"></asp:Label>        </p>        <p>            <asp:RadioButton ID="rdbStudent" runat="server" Text="考生" GroupName="1" AutoPostBack="True" OnCheckedChanged="rdbStudent_CheckedChanged" />            <asp:RadioButton ID="rdbWorker" runat="server"  Text="考务人员" GroupName="1" />        </p>        <p>                <asp:Label ID="Label4" runat="server" Text="账号"></asp:Label>            <asp:TextBox ID="txtAccount" runat="server" style="margin-bottom: 5px" ></asp:TextBox>        </p>        <p>                <asp:Label ID="Label3" runat="server" Text="密码"></asp:Label>            <asp:TextBox ID="txtPassWord" runat="server" style="margin-bottom: 5px" ></asp:TextBox>        </p>        <p>            <asp:Button ID="btnLogin" runat="server" OnClick="Button1_Click" Text="登录" />        </p>    </form></body></html></span>

后台C#代码：

<span style="font-size:24px;">using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace Session实验{    public partial class Seession : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            this.IsWho();        }        protected void redirectpatch( string loginName,string passWord)        {            if (rdbWorker.Checked==true )            {                string userInfo = loginName;                if (loginName == "")                {                    Label2.Text = "账号不能为空";                }                else                {                    //Session["userInfo"] = new Seession();                                        Session["loginname"] = userInfo;                    Session["Password"] = passWord;                }            }            if(rdbStudent.Checked==true )            {                Label1.Text = "当前账户是考生，若您为考务人员请输入账户后登录";                Session["loginname"] = null;            }        }        protected void Button1_Click(object sender, EventArgs e)        {                                   this.redirectpatch(txtAccount.Text,txtPassWord.Text);                        this.IsWho();        }        protected void IsWho()        {            if (Session["loginname"] != null)            {                Label1.Text = "当前登录的是考务人员，用户名：" +(string)Session["loginname"];            }            else            {                Label1.Text = "当前账户是考生，若您为考务人员请输入账户后登录";            }        }           protected void rdbStudent_CheckedChanged(object sender, EventArgs e)        {            txtAccount.Text = "";            txtPassWord.Text = "";        }               }}</span>

Cookie的小例子

   protected void Page_Load(object sender, EventArgs e)        {                 }        protected void Button1_Click(object sender, EventArgs e)        {            //读取Cookie            HttpCookie getcook = Request.Cookies["newcookie"];            Response.Write(HttpUtility.UrlDecode(getcook.Values["name"]));            Response.Write("<br>" + (getcook.Values["age"]));            Response.Write("<br>" + getcook.Values["dt"]);            //Response.Write("<br>" + getcook.Values["name"]);        }        protected void Button2_Click(object sender, EventArgs e)        {            HttpCookie nc = new HttpCookie("newcookie");            nc.Values["name"] = HttpUtility.UrlEncode("天轰穿");            nc.Values["age"] = "27";            nc.Values["dt"] = DateTime.Now.ToString();            Response.Cookies.Add(nc);            Response.Write("Cookie写入成功！");        }    }
