在ASP.NET中创建自定义URL令牌(如MOSS) [英] Creating custom URL tokens in ASP.NET (a la MOSS)

问题描述

在ASP.NET中，波浪号(〜)被视为URL中的令牌，并将以该前缀为前缀的路径视为相对于应用程序根目录的路径.这是众所周知的功能.

In ASP.NET, the tilde (~) is treated as a token in URLs and treats paths prefixed with that as relative to the application root. This is well-known functionality.

在MOSS中，还有其他标记，例如〜sitecollection/mypath ...，它们的行为类似，但是将路径视为相对于网站集根目录的路径.这是如何完成的?经过粗略的搜索后，我找不到有关如何向.NET URL解析机制添加此类令牌的任何信息.

In MOSS, there are other tokens, such as ~sitecollection/mypath... which behaves in a similar way, but treats the path as relative to the site collection root. How is this accomplished? After a cursory search I could not find any info on how to add tokens like this to the .NET URL resolution mechanism.

推荐答案

它可能不是唯一的地方，但是 SPUrlExpressionBuilder 来进行声明使用:

It may not be the only place, but SPUtility.GetServerRelativeUrlFromPrefixedUrl() will parse URLs with ~site and ~sitecollection. MOSS also provides SPUrlExpressionBuilder for declarative use:

<link runat="server" rel="stylesheet" type="text/css"
      href="<% $SPUrl:~SiteCollection/Style Library/MyStyles/style.css %>" />
