            Console::WriteLine( "\t BindingField: {0}", bInfo.BindingField );
            Console::WriteLine( "\t BindingMember: {0}", bInfo.BindingMember );
            Console::WriteLine();
         }
      }
   }

private void PrintBindingMemberInfo()
{
   Console.WriteLine("\n BindingMemberInfo");
