You need to implement your own IComparer do the specialized sort:

using System;
using System.IO;
using System.Collections;
                                                                                
public class SortFiles
{
   public class CompareFileByDate :IComparer
   {
      int IComparer.Compare(Object a, Object b)
      {
         FileInfo fia = new FileInfo((string)a);
         FileInfo fib = new FileInfo((string)b);
                                                                                
         DateTime cta = fia.CreationTime;
         DateTime ctb = fib.CreationTime;
                                                                                
         return DateTime.Compare(cta, ctb);
      }
   }
                                                                                
   public static void Main()
   {
      string [] files = System.IO.Directory.GetFiles("..");
                                                                                
      IComparer fileComparer = new CompareFileByDate();
      Array.Sort(files, fileComparer);
                                                                                
      foreach ( string f in files )
      {
         Console.WriteLine(f);
      }
                                                                                
   }
}
