Getting relative virtual path from physical path

Question

How can I get the relative virtual path from the physical path in asp.net? The reverse method is like below:

Server.MapPath(\"Virtual Path Here\");
         


        

Answer 1

Request.ServerVariables["APPL_PHYSICAL_PATH"]

is fine, but not always. It is available only if there's a HTTP request.

On the other hand the call

HostingEnvironment.ApplicationPhysicalPath

is always available.
