   numberOfCounters = Int32::Parse( Console::ReadLine() );
   array<CounterCreationData^>^myCounterCreationData = gcnew array<CounterCreationData^>(numberOfCounters);
   for ( int i = 0; i < numberOfCounters; i++ )
   {
      Console::Write( "Enter the counter name for {0} counter : ", i );
      myCounterCreationData[ i ] = gcnew CounterCreationData;
      myCounterCreationData[ i ]->CounterName = Console::ReadLine();

   }
   CounterCreationDataCollection^ myCounterCollection = gcnew CounterCreationDataCollection( myCounterCreationData );

   // Create the category.
   PerformanceCounterCategory::Create( myCategoryName, "Sample Category", myCounterCollection );
