我看很多人都用字串的 IndexOf 方法與 Substring 方法:
[code:c#]
Request.Url.PathAndQuery.Substring(1, Request.Url.PathAndQuery.IndexOf("/", 1)-1)
[/code]
這實在太埋沒 .NET 的強大設計了,事實上在 Request 物件就已經提供很多方便的屬性(Property)可供取得網址的片段。
底下這張表就是各種跟 Browser Request 的網址相關的屬性與用法:

System.IO.Path.GetDirectoryName(Request.PhysicalPath) | D:\Projects\Solution\web\News\Press |

System.IO.Path.GetFileName(Request.PhysicalPath) | Content.aspx |
