检测客户端显示器分辨率、浏览器类型和客户端IP-.NET教程,远程及网络应用:站长天空

下面的代码实现了检测客户端显示器分辨率、浏览器类型和客户端ip的功能。你可以把客户端信息保存到session，viewstate等中以便在其它的页面直接使用。

例子

clientpeek.aspx

<%@ page language="vb" enableviewstate="false" codebehind="clientpeek.aspx.vb"
autoeventwireup="false" inherits="aspxweb.clientpeek"%>
<!doctype html public "-//w3c//dtd html 4.0 transitional//en" >
