      ClassLevel6 nestedClass = new ClassLevel6();
      nestedClass.Level6Method();
   }
   catch (Exception e)
   {
      Console.WriteLine(" Level5Method exception handler");

      StackTrace st = new StackTrace();

      // Display the most recent function call.
      StackFrame sf = st.GetFrame(0);
      Console.WriteLine();
      Console.WriteLine("  Exception in method: ");
      Console.WriteLine("      {0}", sf.GetMethod());

      if (st.FrameCount >1)
      {
         // Display the highest-level function call
         // in the trace.
         sf = st.GetFrame(st.FrameCount-1);
         Console.WriteLine("  Original function call at top of call stack):");
         Console.WriteLine("      {0}", sf.GetMethod());
      }

      Console.WriteLine();
      Console.WriteLine("   ... throwing exception to next level ...");
      Console.WriteLine("-------------------------------------------------\n");
      throw e;
   }
