asp.net页面传值测试实例代码(前后台)

  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" %>

  <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: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");

  }

  }

  }

  //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 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);

  }

  }

  }
