====以下是一个取得IP和操作系统以及浏览器的例子=========
string privada getIp()
{/*穿过代理服务器取远程用户真实IP地址：*/
if(Request.ServerVariables["HTTP_VIA"]!=nulo)
retornar Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
outro
return Request.ServerVariables["REMOTE_ADDR"].ToString();
}
Label2.Text =getIp();
HttpBrowserCapabilities bc = new HttpBrowserCapabilities();
bc = Solicitação.Navegador;
string xitong = "你的操作系统为";
Label3.Text=xitong+bc.Platform + "浏览器类型:" + bc.Type;
