ResolveUrl without an ASP.NET Page

I am looking for a way to resolve a relative url the way you would with a page or control instance (MSDN Docs) such as:

Page.ResolveUrl("~/common/Error.aspx");

...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 here?

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

Try to get the page from the handler and use ResolveUrl, or create a Control object...

(HttpContext.Current.Handler as Page).ResolveUrl("~/virtualpath");

Or use VirtualPathUtility.ToAppRelative(string) or VirtualPathUtility.ToAbsolute(string)

For example:

System.Web.VirtualPathUtility.ToAbsolute("~/Styles/Contoso.xslt");

returns

/WebSite/Styles/Contoso.xslt

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: 

Controls_myController ctrl = Page.LoadControl(Page.ResolveUrl("controls/myController.ascx"));

Hope this helps.

This question on SO (ASP.Net: Using System.Web.UI.Control.ResolveUrl() in a shared/static function) looks kind of helpful...Basically, you can use the VirtualPathUtility 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!
