Contoh

Contoh berikut mengambil CounterCreationData entri dari CounterCreationDataCollection dan menggunakan IndexOf metode untuk menampilkan nama dan indeksnya.

String^ myCategoryName;
int numberOfCounters;
Console::Write( "Enter the category Name : " );
myCategoryName = Console::ReadLine();
// Check if the category already exists or not.
if (  !PerformanceCounterCategory::Exists( myCategoryName ) )
{
   Console::Write( "Enter the number of counters : " );
   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 );
   CounterCreationData^ myInsertCounterCreationData = gcnew CounterCreationData(
      "CounterInsert","",PerformanceCounterType::NumberOfItems32 );
