Answer 1

you can use something like that :

 public static class Extensions        {
        public static string RelativePath(this HttpServerUtility utility, string path, HttpRequest context)
        {
            return path.Replace(context.ServerVariables["APPL_PHYSICAL_PATH"], "/").Replace(@"\", "/");
        }
    }

and you call

Server.RelativePath(path, Request);

Isn't this the reverse of what the OP asked? – Calley

thanks, its good solution but i prefer to use HttpServerUtilityBase instead of HttpServerUtility abnd HttpRequestBase instead of HttpRequestBase. working well also. – Idun

+1 even if I think it's not a good idea to add an extension to a class where at least one property or method are used in the helper method. In this case, the RelativePath could be at a better place in a helper class like PathResolver. What do you think? – Zoophilia

@Zoophilia Yes, it's just a quick sample but actually you could create a helper class that fits your needs called like you said a PathResolver. – Thessalonians

Answer 2

You can do the following to get the relative path.

String filePath = @"C:\bla\bla\Content\Upload\image.jpg";

String serverPath = Request.PhysicalPath;
String relativePath = filePath.Substring(serverPath.Length, filePath.Length - serverPath.Length);
