WebForm_1.aspx内容如下: 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm_1.aspx.cs" Inherits="页面传值.WebForm_1" %> 
<!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:Table ID="TableLogin" runat='server'> 
<asp:TableRow> 
<asp:TableCell><label>用户名：</label></asp:TableCell> 
<asp:TableCell><asp:TextBox ID="UserName" runat="server" Width="150px"></asp:TextBox></asp:TableCell> 
</asp:TableRow> 
<asp:TableRow> 
<asp:TableCell><label>密码：</label></asp:TableCell> 
<asp:TableCell><asp:TextBox ID="PassWord" runat="server" Width="150px"></asp:TextBox></asp:TableCell> 
</asp:TableRow> 
<asp:TableRow> 
<asp:TableCell><label>验证密码：</label></asp:TableCell> 
<asp:TableCell><asp:TextBox ID="ConfimPWD" runat="server" Width="150px"></asp:TextBox></asp:TableCell> 
</asp:TableRow> 
<asp:TableRow> 
<asp:TableCell><asp:Button ID="Confirm" runat="server" Text="确认" Width="50px" OnClick="Confirm_Click" /></asp:TableCell> 
</asp:TableRow> 
</asp:Table> 
</div> 
</form> 
</body> 
</html>

WebForm_2.aspx页面如下： 

<%@ Reference Page="~/WebForm_1.aspx" %> 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm_2.aspx.cs" Inherits="页面传值.WebForm_2" %> 
<!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> 
</div> 
</form> 
</body> 
</html>

WebForm_1.aspx.cs文件如下： 

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
namespace 页面传值 
{ 
public partial class WebForm_1 : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
} 
public string un//得到用户名 
{ 
get 
{ 
return UserName.Text; 
} 
} 
public string pwd//得到密码 
{ 
get 
{ 
return PassWord.Text; 
} 
} 
public string conpwd//得到确认密码 
{ 
get 
{ 
return ConfimPWD.Text; 
} 
} 
/// <summary> 
/// 向WebForm_2.aspx页面传值 
/// </summary> 
/// <param name="sender"></param> 
/// <param name="e"></param> 
protected void Confirm_Click(object sender, EventArgs e) 
{ 
//1：QueryString页面传值 
//string url = "WebForm_2.aspx?un=" + UserName.Text + "&userpassword=" + PassWord.Text + "&conPwd=" + ConfimPWD.Text; 
//Response.Redirect(url); 
//2：Session传值 
//Session["un"] = UserName.Text; 
//Session["pwd"] = PassWord.Text; 
//Session["conpwd"] = ConfimPWD.Text; 
//Server.Transfer("WebForm_2.aspx"); 
//3：使用cookie对象传值 
//HttpCookie cookie_name = new HttpCookie("un"); 
//cookie_name.Value = UserName.Text; 
//HttpCookie cookie_pwd = new HttpCookie("pwd"); 
//cookie_pwd.Value = PassWord.Text; 
//HttpCookie cookie_conpwd = new HttpCookie("conpwd"); 
//cookie_conpwd.Value = ConfimPWD.Text; 
//Response.AppendCookie(cookie_name); 
//Response.AppendCookie(cookie_pwd); 
//Response.AppendCookie(cookie_conpwd); 
//Server.Transfer("WebForm_2.aspx"); 
//4：使用application对象传值，类似session传值，作用范围全局所有用户 
//Application["un"] = UserName.Text; 
//Application["pwd"] = PassWord.Text; 
//Application["conpwd"] = ConfimPWD.Text; 
//Response.Redirect("WebForm_2.aspx"); 
Server.Transfer("WebForm_2.aspx"); 
} 
} 
}

WebForm_2.aspx.cs文件如下： 

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
namespace 页面传值 
{ 
public partial class WebForm_2 : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
//QueryTransfer(); 
//SessionTransfer(); 
//CookieTransfer(); 
//ApplicationTransfer(); 
Transfer(); 
} 
public void QueryTransfer()//接收QueryString传值，来自于WebForm_1页面的值 
{ 
string strUserName = Request.QueryString["un"].ToString(); 
string strPassword = Request.QueryString["userpassword"].ToString(); 
string strPWD = Request.QueryString["conPwd"].ToString(); 
Response.Write("用户名为" + strUserName + "<br/>" + "密码为" + strPassword + "<br/>" + "确认密码为" + strPWD); 
} 
public void SessionTransfer()//接收session传值,来自于WebForm_1页面的值 
{ 
string strUserName = Session["un"].ToString(); 
string strPassword = Session["pwd"].ToString(); 
string strPWD = Session["conpwd"].ToString(); 
Response.Write("用户名为" + strUserName + "<br/>" + "密码为" + strPassword + "<br/>" + "确认密码为" + strPWD); 
Session.Remove("un"); 
Session.Remove("pwd"); 
Session.Remove("conpwd"); 
} 
public void CookieTransfer()//接收cookie传值，来自于WebForm_1页面的值 
{ 
string strUserName = Request.Cookies["un"].Value.ToString(); 
string strPassword = Request.Cookies["pwd"].Value.ToString(); 
string strPWD = Request.Cookies["conpwd"].Value.ToString(); 
Response.Write("用户名为" + strUserName + "<br/>" + "密码为" + strPassword + "<br/>" + "确认密码为" + strPWD); 
} 
public void ApplicationTransfer()//接收Application传值，来自于WebForm_1页面的值 
{ 
Application.Lock(); 
string strUserName = Application["un"].ToString(); 
string strPassword = Application["pwd"].ToString(); 
string strPWD = Application["conpwd"].ToString(); 
Application.UnLock(); 
if (strPassword != strPWD) 
{ 
Response.Write("您确认的密码错误，请重新输入！<br/>"); 
Server.Transfer("WebForm_1.aspx"); 
} 
Response.Write("用户名为" + strUserName + "<br/>" + "密码为" + strPassword + "<br/>" + "确认密码为" + strPWD); 
} 
public void Transfer()//Transfer传值，来自WebForm_1.aspx页面的值 
{ 
WebForm_1 wf1; 
wf1 = (WebForm_1)Context.Handler; 
string strUserName = wf1.un; 
string strPassword = wf1.pwd; 
string strPWD = wf1.conpwd; 
Response.Write("用户名为" + strUserName + "<br/>" + "密码为" + strPassword + "<br/>" + "确认密码为" + strPWD); 
} 
} 
}
