Answer 1

Once you know your path you can use IO.Directory.GetFiles() method.

IO.Directory.GetFiles("\translated\path","27_*.jpg").Count()

will give you what you're looking for.

Answer 2

Using the System.IO namespace, you can do something like this

public File[] GetUserFiles(int userId)
{
   List<File> files = new List<File>();

   DirectoryInfo di = new DirectoryInfo(@"c:\folderyoulookingfor");
   foreach(File f in di.GetFiles())
   {
      if(f.ToString().StartsWith(userId.ToString()))
         files.Add(f);
   }
   return file.ToArray();
}
