Exemples

L’exemple de code suivant montre comment obtenir et définir la CounterHelp propriété. Cet exemple crée deux compteurs et définit leur CounterHelp propriété à l’aide de différentes techniques. Lorsque le premier compteur est initialisé, les CounterHelp données sont transmises au constructeur, tandis que le deuxième compteur définit explicitement la propriété.

#using <System.dll>

using namespace System;
using namespace System::Diagnostics;

int main()
{
   CounterCreationDataCollection^ myCol = gcnew CounterCreationDataCollection;
   
   // Create two custom counter objects.
   CounterCreationData^ myCounter1 = gcnew CounterCreationData( "Counter1","First custom counter",PerformanceCounterType::CounterDelta32 );
   CounterCreationData^ myCounter2 = gcnew CounterCreationData;
   
   // Set the properties of the 'CounterCreationData' Object*.
   myCounter2->CounterName = "Counter2";
   myCounter2->CounterHelp = "Second custom counter";
   myCounter2->CounterType = PerformanceCounterType::NumberOfItemsHEX32;
   
   // Add custom counter objects to CounterCreationDataCollection.
   myCol->Add( myCounter1 );
   myCol->Add( myCounter2 );
   if ( PerformanceCounterCategory::Exists( "New Counter Category" ) )
      PerformanceCounterCategory::Delete( "New Counter Category" );
   
   // Bind the counters to a PerformanceCounterCategory.
   PerformanceCounterCategory^ myCategory = PerformanceCounterCategory::Create( "New Counter Category", "Category Help", myCol );
