Request對象是HttpRequest類的一個實例，它提供對當前頁請求的訪問，其中包括請求標題、Cookie、客戶端證書、查詢字符串等，你可以使用此類來讀取瀏覽器已經發送的內容。
新建一個網站，包括兩個網頁，代碼如下：
1、Default.aspx代碼：
<%@ 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>Request對象</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="讀取與傳值" OnClick="Button1_Click" /></div>
</form>
</body>
</html>
Default.aspx.cs代碼：

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)
{
Application["id"] = TextBox1.Text;
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("Default2.aspx?id=" + TextBox1.Text.Trim() + "");
}
}
2、Default2.aspx代碼：
<%@ 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>
<body>
<form id="form1" runat="server">

<br />
<asp:Label ID="Label1" runat="server" Height="28px" Text="Label" Width="326px"></asp:Label></div>
</form>
</body>
</html>
Default2.aspx.cs代碼：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = Page.Request.QueryString["id"].ToString();
Response.Write(Request.Browser.Platform);
Response.Write("<br>");
Response.Write(Request.MapPath("Default2.aspx"));
Response.Write("<br>");
Response.Write(Request.UserHostAddress);
Response.Write("<br>");
Response.Write(Request.Url.OriginalString);
