在ASPX頁面中每個標簽的text屬性將在運行時動態改變，這取决於用戶配置/瀏覽器。

首先，讓我們創建一個布局，顯示的信息：

<form id="form1" runat="server">
<div>

Browser Capabilities:<br />
<table style="width: 95%; position: static; text-align: left"> 
<tr> 
<td style="vertical-align: top; width: 30%; text-align: right">

<td style="vertical-align: top; width: 70%; text-align: left">
<asp:Label ID="Label1" runat="server"></asp:Label></td>
</tr>
<tr> 
<td style="vertical-align: top; width: 30%; text-align: right">

<td style="vertical-align: top; width: 70%; text-align: left">

下面的代碼檢查瀏覽器對象的特定屬性值。
我們是能夠輸出這些值的用戶，通知他們，但我們還可以在代碼中使用這些值，以顯示我們的不同，以不同的用戶。例如，不使用ActiveX控件，如果用戶的瀏覽器不支持ActiveX 
的代碼背後應該是這個样子：

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)

{ 
Label1.Text = "This browser supports ActiveX Controls.";
}
else
