WebForm_1.aspx内容如下:
复制代码 代码如下:

<%@ 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：
复制代码 代码如下:

<%@ 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：
复制代码 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;
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");
}
}
}

}
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();

{
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);
}
}
}
