Hi all. I am trying to get all images from folder but ,this folder also include sub folders. like /photos/person1/ and /photos/person2/ .I can get photos in folder like

  path= System.IO.Directory.GetCurrentDirectory() + "/photo/" + groupNO + "/";
 public List<String> GetImagesPath(String folderName)
    {

        DirectoryInfo Folder;
        FileInfo[] Images;

        Folder = new DirectoryInfo(folderName);
        Images = Folder.GetFiles();
        List<String> imagesList = new List<String>();

        for (int i = 0; i < Images.Length; i++)
        {
            imagesList.Add(String.Format(@"{0}/{1}", folderName, Images[i].Name));
           // Console.WriteLine(String.Format(@"{0}/{1}", folderName, Images[i].Name));
        }


        return imagesList;
    }

But how can I get all photos in all sub folders? I mean I want to get all photos in /photo/ directory at once.
