A have a function that shall create a new UnifiedDirectory and then save file in it but a only get

System.NullReferenceException: Objektreferensen har inte angetts till en instans av ett objekt

when directory bellow is equal with null or do not exist.

Have found some links like

http://blog.fredrikhaglund.se/blog/2007/12/05/episerver-using-the-new-unified-file-system/

That did help a lot but this last part will not work hmmmm...

UnifiedDirectory directory = HostingEnvironment.VirtualPathProvider.GetDirectory(path) as UnifiedDirectory;

if (directory != null)

file2 = directory.CreateFile(VirtualPathUtility.GetFileName(this.m_targetPath));

else //this do not work

UnifiedDirectory ud = UnifiedDirectory.CreateDirectory(path);

file2 = ud.CreateFile(VirtualPathUtility.GetFileName(this.m_targetPath));

Hi Per.

I usally use this approach:

public static void SaveFile(string newpath, byte[] bytes)
{

  UnifiedDirectory dir;

  string virtualDir = VirtualPathUtility.GetDirectory(newpath);
  string virtualFile = VirtualPathUtility.GetFileName(newpath);

  if (HostingEnvironment.VirtualPathProvider.DirectoryExists(virtualDir))
     dir = VirtualPathHandler.Instance.GetDirectory(virtualDir, true) as UnifiedDirectory;

  else
   dir = UnifiedDirectory.CreateDirectory(virtualDir);

  if (dir != null)
  {
    dir.BypassAccessCheck = true;
    UnifiedFile newFile = dir.CreateFile(virtualFile);
    Stream newImage = newFile.Open(FileMode.Create, FileAccess.Write);
    newImage.Write(bytes, 0, bytes.Length);
    newImage.Close();
  }
}

newpath is the path to the new file, while bytes is the an bytearray of the file to save.

Hope this helps!

BR, Tore

Thanks for the help, you code send me in the rigth way

It seems that it was the path sting that was causing some problem in my case
