如何得到客户端的机器名

        //IP
        System.Net.IPAddress ip = System.Net.IPAddress.Parse(Request.UserHostAddress);
        System.Net.IPHostEntry ihe = Dns.GetHostEntry(ip);
        //机器名
        string clientname = ihe.HostName;
        Response.Write("clientname: " + clientname);

        string info = "";
        info += "<br/>当前用户电脑名称：" + System.Net.Dns.GetHostName();
        info += "<br/>当前电脑名：" + System.Environment.MachineName;
        Response.Write(info);

string info ="客户端IP："+ Page.Request.UserHostAddress;
info += "<br/>用户信息：" + Page.User;
info += "<br/>服务器电脑名称：" + Page.Server.MachineName;
info += "<br/>当前用户电脑名称：" + System.Net.Dns.GetHostName();
info += "<br/>当前电脑名：" + System.Environment.MachineName;
info += "<br/>当前电脑所属网域：" + System.Environment.UserDomainName;
info += "<br/>当前电脑用户：" + System.Environment.UserName;
info += "<br/>浏览器类型："+Request.Browser.Browser;
info += "<br/>浏览器标识：" + Request.Browser.Id;
info += "<br/>浏览器版本号：" + Request.Browser.Version;
info += "<br/>浏览器是不是测试版本："+Request.Browser.Beta;
info += "<br/>浏览器的分辨率(像素)：" + Request["width"].ToString() + "*" + Request["height"].ToString();//1280/1024
info += "<hr/>";
info += "<br/>客户端的操作系统："+Request.Browser.Platform;
info += "<br/>是不是win16系统："+Request.Browser.Win16;
info += "<br/>是不是win32系统：" +Request.Browser.Win32;
