有些時候我們需要抓到網址中的某一字串來作判斷，你還在用老舊的IndexOf 與 Substring 慢慢組嗎?別鬧了.NET有提供更聰明的作法，以下就列出一張表，各位就很清楚啦。
假設我們的網址為http://demo.tc/Default3.aspx?id=1019&uu=77
Request.ApplicationPath //output：/ Request.PhysicalPath //output：磁碟機代號:\父目錄\子目錄\Default3.aspx System.IO.Path.GetDirectoryName(Request.PhysicalPath) //output：磁碟機代號:\父目錄\子目錄 Request.PhysicalApplicationPath //output：磁碟機代號:\父目錄\子目錄\ System.IO.Path.GetFileName(Request.PhysicalPath) //output：Default3.aspx Request.CurrentExecutionFilePath //output：/Default3.aspx Request.FilePath //output：/Default3.aspx Request.Path //output：/Default3.aspx Request.RawUrl //output：/Default3.aspx?id=1019&uu=77 Request.Url.AbsolutePath //output：/Default3.aspx Request.Url.AbsoluteUri //output：http://demo.tc/Default3.aspx?id=1019(這是上一頁的網址) Request.Url.Scheme //output：http Request.Url.Host //output：demo.tc Request.Url.Port //output：80 Request.Url.Authority //output：demo.tc Request.Url.LocalPath //output：/Default3.aspx Request.PathInfo //output： Request.Url.PathAndQuery //output：/Default3.aspx?id=1019&uu=77 Request.Url.Query //output：?id=1019&uu=77 Request.Url.Fragment //output： Request.Url.Segments[0] //output：/ Request.Url.Segments[1] //output：Default3.aspx
▲但是因為小鋪的網址太短了，所以看不太出端倪，不如您就把下方code複製下來貼到您的環境中去跑就可以一清二楚啦。
