I pass the the virtual path, but got exception of null refrence. I can get the extention by using VirtualPathUtility.GetExtension(p). I need to get the file size.

eg.

            string p=filepath.ToString();
                string size=string.Empty;
                string extentionIcon=string.Empty;

                System.IO.Stream file = VirtualPathMappedProvider.OpenFile(p);
                if(file!=null)
                    size = GetFileSizeString(file.Length);

                extentionIcon = GetFileIcon(VirtualPathUtility.GetExtension(p));

Try with:

var file = HostingEnvironment.VirtualPathProvider.GetFile(p) as UnifiedFile;

if (file != null)
{
    size = file.Length;
}

Hope this helps.
