This question on SO (<a href="https://stackoverflow.com/questions/26796/asp-net-using-system-web-ui-control-resolveurl-in-a-shared-static-function">ASP.Net: Using System.Web.UI.Control.ResolveUrl() in a shared/static function</a>) looks kind of helpful...Basically, you can use the <a href="http://msdn.microsoft.com/en-us/library/system.web.virtualpathutility.aspx" rel="nofollow noreferrer">VirtualPathUtility</a> class which is under the System.Web namespace. There is an additional answer to that question which says to be careful of QueryString parameters, but a solution to that is also provided.

At the same time, Rick Strahl's code is pretty neat!

Try to get the page from the handler and use <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.control.resolveurl.aspx"><code>ResolveUrl</code></a>, or create a Control object...

<pre><code>(HttpContext.Current.Handler as Page).ResolveUrl("~/virtualpath");
</code></pre>

Or use <a href="http://msdn.microsoft.com/en-us/library/ms150163.aspx"><code>VirtualPathUtility.ToAppRelative(string)</code></a> or <a href="http://msdn.microsoft.com/en-us/library/ms150160.aspx"><code>VirtualPathUtility.ToAbsolute(string)</code></a>

For example:

<pre><code>System.Web.VirtualPathUtility.ToAbsolute("~/Styles/Contoso.xslt");
</code></pre>

returns

<pre><code>/WebSite/Styles/Contoso.xslt
</code></pre>

blocks|key|800555|text|使用类似这样的东西-+Controls是应用程序中的文件夹名称，myController是控制器名称。要创建和实例化并加载控制器，您可以通过以下方式完成：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|800556|Controls_myController+ctrl+=+Page.LoadControl(Page.ResolveUrl("controls/myController.ascx"));|code-block|syntax|javascript|800557|希望这能有所帮助。|800558|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Use something like this - 
Controls is a folder name in your application and myController is the controller name. to create and instance and load the controller you can do it by: 

<pre><code>Controls_myController ctrl = Page.LoadControl(Page.ResolveUrl("controls/myController.ascx"));
</code></pre>

Hope this helps.

I am looking for a way to resolve a relative url the way you would with a page or control instance (<a href="http://msdn.microsoft.com/en-us/library/system.web.ui.control.resolveurl(v=vs.71).aspx" rel="noreferrer">MSDN Docs</a>) such as:

<pre><code>Page.ResolveUrl("~/common/Error.aspx");
</code></pre>

...but when I only have an HttpContext available to me, such as when I am in a HttpHandler. 

Will I need to use a custom function, such as the one seen <a href="http://www.west-wind.com/weblog/posts/154812.aspx" rel="noreferrer">here</a>?

Or is there a way to get at the underlying function used by the Page.

ResolveUrl without an ASP.NET Page

我正在寻找一种方法来解析相对url，就像您使用页面或控件实例的方式一样(，例如：Page.ResolveUrl("~/common/Error.aspx");当我只有一个HttpContext可用时，例如当我在HttpHandler中时，...but。我是否需要使用自定义函数，比如看到的或者有没有办法获得页面使用的底层...
