How get the virtual path based on the physical path?

Server.MapPath("~/page.aspx") returns the physical file path based on
the specified virtual path. Is there any reverse method to get the
virtual path based on the physical path (both pathes belong to the
same web application)?
Usually I do in this way:

virtualFilePath =
physicalFilePath.Replace(physicalRootDirectoryPath,"~/")

Perhaps, is there standard inbuilt method?

Or, maybe, anyone know how to get virtual files pathes in some virtual
directory without casting the directory virtual path to phisical
path.
I mean without this: System.IO.Directory.GetFiles(Server.MapPath("~/
images"))

Hello marss,

try ResolveUrl

PS: look at Request.ServerVariables("APPL_PHYSICAL_PATH") too

Thank you Michael.

Probably, I do not clearly stated the question.
I have a virtual folder path: "~/images".
I want to get virtual pathes to the files in this folder, e.g.: "~/
images/1.gif", "~/images/2.gif" and so on.

Now I do it in this way.
string virtualFolder = "~/images";
string physicalFolder = Server.MapPath(virtualFolder);
string[] files = System.IO.Directory.GetFiles(physicalFolder);
for (int i = 0; i < files.Length; i++)
files = files.Replace(physicalFolder,
virtualFolder).Replace("\\", "/");

Is there a simpler solution?

Thank for answer, Juan

Unfortunately, none of these methods do that I want.

I wrote the real example of my task above. This code works, but it is
not very good, IMHO.
Too many Replace method calls. Also there is converting from the
virtual path to the physical path and conversely, although I have the
virtual folder path at the input and I want virtual files pathes at
the output.

I am interested whether is there a method like this (pseudo code):

string[] files = ...VirtualDirectory.GetFiles("~/images")
where files is an array of the virtual files pathes: "~/images/1.gif",
"~/images/2.gif" ...

or like this (pseudo code):
string file = ...GetVirtualPath("E:\Inetpub\wwwroot\test\images
\1.gif")
where value of the file should be "~/images/1.gif"

I am not sure whether it is possible, I am just interested.

Thanks again.
