NET内置对象
ASP.NET为方便程序员的开发提供了一些内置对象,包括Response、Request、Application、Session、Server和Cookies等六种。
Response对象
Response对象是HttpResponse类的一个实例,它允许将数据作为请求的结果发送到浏览器中,并提供有关响应的信息。
新建一个网站,包括两个网页,代码如下:
1、Default.aspx代码:
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”_Default” %>
<!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>Response对象</title>
</head>
<body>
<form id=”form1″ runat=”server”>
<div>
<asp:Button ID=”Button1″ runat=”server” onClick=”Button1_Click” Text=”弹出窗口” /></div>
</form>
</body>
</html>
Default.aspx.cs代码:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.WriteFile(@”D:\\My Documents\\Visual Studio 2005\\WebSites\\Response对象\\test.txt”);
Response.Write(“<br>”);
Response.Write(“写入成功”);
}
protected void Button1_Click(object sender, EventArgs e)
{
//Response.Redirect(“Default2.aspx”);直接转到Default2.aspx
//弹出窗口
Response.Write(“<script>window.open(‘Default2.aspx’,”,width=’330px’,height=’220px’);location=’javascript:history.go(-1)’;</script>”);
}
}
2、Default2.aspx代码:
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default2.aspx.cs” Inherits=”Default2″ %>
<!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>弹出窗口</title>
</head>
<body style=”width:200px;height:100px;”>
<form id=”form1″ runat=”server”>
<div style=”width:330px;height:201px”>
这是一个弹出窗口!
</div>
</form>
</body>
</html>
