应用相对路径到ASP.NET中的物理路径

Question

I simply try to convert "~/Telerik.Web.UI.WebResource.axd?imgid=310aa01d42ba47e1af090c60b520dd8e&type=rbi" this path to physical path.

I simply tried below code but it throws Exception and says "Illegal characters in path".

Server.MapPath("~/Telerik.Web.UI.WebResource.axd?imgid=310aa01d42ba47e1af090c60b520dd8e&type=rbi") 

I am not exactly sure it is possible to do that or not.

Edit: I actualy have RadBinaryImage That holds the url. I want to have byte array from RadBinaryImage and this is what i try to access file.

Answer 1

尝试

Server.MapPath("~/Telerik.Web.UI.WebResource.axd") + "?imgid=310aa01d42ba47e1af090c60b520dd8e&type=rbi)"

Answer 2

How about [control].ResolveUrl instead?

MapMath is looking for a file, which & is not accepted in a file path. You're just looking to get the "absolute URL" (or at least one that's folder agnostic) that the client can use.

Telerik.Web.UI.WebResource.axd is not physical resource, so it hasn't an equivalent on disk. Probably is loaded/readed from a dll by its corresponding handler.
