現在我們團隊在開發手機站,當中遇到一個問題.就是每張頁面得傳一個參數,而這個參數又不是從固定的頁面進來的,也就是說無論從哪張頁面進來,參數都要全站點的頁面傳下去,目前找不到解決辦法.從網上down了一篇代碼,可是RegexResource.ACTION,RegexResource.HREF報錯,麻煩高手幫忙解決一下.下面我把代碼貼上,小弟跪謝... ? using System;using System.Text;using System.Web;using System.IO;using System.Text.RegularExpressions; namespace ThreeHegemony.Utility{?? ??? /// <summary>??? /// Auther:?????
