This might answer your question:

However, I can't currently provide an example, because I have got a lot of work to do. When I'll find some time I'll send detailed information.

Answer 2

After some more research I was able to create a method to get the physical path of a virtual IIS directory:

public static string VirtualToPhysicalPath(string vPath) {
    // Remove query string:
    vPath = Regex.Replace(vPath, @"\?.+", "").ToLower();

    // Check if file is in standard folder:
    var pPath = System.Web.Hosting.HostingEnvironment.MapPath("~" + vPath);
    if (System.IO.File.Exists(pPath)) return pPath;

    // Else check for IIS virtual directory:
    var siteName = System.Web.Hosting.HostingEnvironment.ApplicationHost.GetSiteName();
    var sm = new Microsoft.Web.Administration.ServerManager();
    var vDirs = sm.Sites[siteName].Applications[0].VirtualDirectories;
    foreach (var vd in vDirs) {
        if (vd.Path != "/" && vPath.Contains(vd.Path.ToLower())) pPath = vPath.Replace(vd.Path.ToLower(), vd.PhysicalPath).Replace("/", "\\");
    }
    return pPath;
}

Caveat: this solution assumes that you only have a root application (Applications[0]).

Answer 3

The following should work just fine:

var physicalPath = HostingEnvironment.MapPath("~/MyVirtualDirectory");

Answer 4

This is what worked for me:

string physicalPath =    
System.Web.Hosting.HostingEnvironment.MapPath(HttpContext.Current.Request.ApplicationPath);

Answer 5

What if you try this little snippet?

string physicalPath = HttpContext.Current.Request.MapPath(appPath);

Answer 6

Server.MapPath("~/Images")

is the correct way to go about it as "~" references the root of your application.
