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:
網址:http://localhost:1897/News/Press/Content.aspx/123?id=1#toc | |
Request.ApplicationPath | / |
Request.PhysicalPath | D:\Projects\Solution\web\News\Press\Content.aspx |
System.IO.Path.GetDirectoryName(Request.PhysicalPath) | D:\Projects\Solution\web\News\Press |
Request.PhysicalApplicationPath | D:\Projects\Solution\web\ |
System.IO.Path.GetFileName(Request.PhysicalPath) | Content.aspx |
Request.CurrentExecutionFilePath | /News/Press/Content.aspx |
Request.FilePath | /News/Press/Content.aspx |
Request.Path | /News/Press/Content.aspx/123 |
Request.RawUrl | /News/Press/Content.aspx/123?id=1 |
Request.Url.AbsolutePath | /News/Press/Content.aspx/123 |
Request.Url.AbsoluteUri | http://localhost:1897/News/Press/Content.aspx/123?id=1 |
Request.Url.Scheme | http |
Request.Url.Host | localhost |
Request.Url.Port | 1897 |
Request.Url.Authority | localhost:1897 |
Request.Url.LocalPath | /News/Press/Content.aspx/123 |
