http://www.venetian.com/Checking-Rates/&OFFERCODE=abc123&ARRIVALDATE=06-08-2012&DEPARTUREDATE=09-08-2012&#OFGUESTS=2

这是别人提供给我的一个url，我需要获取参数，Checking-Rates是伪静态页面，现在的问题是#OFGUESTS，假如对方没有处理#符号就直接传过来，那么应该怎么获取这个参数值呢？

        string offerCode = Request.Params["OFFERCODE"];

        string arrivalDate = Request.Params["ARRIVALDATE"];

        string leaveDate = Request.Params["DEPARTUREDATE"];

        string guests = Request.Params["OFGUESTS"];

gusets的值为null

你要在哪里获取？后台还是js？

另外，是从站点中获取还是只是从这个字符串中获取？
