我要寻找一种方式来解决相对URL的方式，你会与一个网页或控件实例（MSDN文档），例如：

  Page.ResolveUrl（〜/普通/ Error.aspx）;
 

...但是当我只有提供给我一个HttpContext的，当我在一个HttpHandler的，如。

我是否需要使用自定义的功能，比如一看到这里

还是有办法让在页面使用的基本功能。

尝试从处理程序中获取页面，并使用ResolveUrl,或创建一个控制对象...

 （HttpContext.Current.Handler为页）.ResolveUrl（〜/ virtualpath）;
 

或者使用VirtualPathUtility.ToAp$p$plative(string)或VirtualPathUtility.ToAbsolute(string)

例如：

  System.Web.VirtualPathUtility.ToAbsolute（〜/风格/ Contoso.xslt）;
 

返回

  /WebSite/Styles/Contoso.xslt
 

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
