====以下是一个取得IP和操作系统以及浏览器的例子========
private string getIp()

else
return Request.ServerVariables["REMOTE_ADDR"].ToString();
}
Label2.Text =getIp();
HttpBrowserCapabilities bc = new HttpBrowserCapabilities();
bc = Request.Browser;
string xitong ="你的操作系统为";
Label3.Text=xitong+bc.Platform + " 浏览器类型:" + bc.Type;
