Voorbeelden

In het volgende voorbeeld worden vermeldingen CounterCreationData opgehaald uit een CounterCreationDataCollection en wordt de IndexOf methode gebruikt om hun namen en indexen weer te geven.

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 = int.Parse(Console.ReadLine());
    CounterCreationData[] myCounterCreationData =
       new CounterCreationData[numberOfCounters];

    for (int i = 0; i < numberOfCounters; i++)
    {
        Console.Write("Enter the counter name for {0} counter ", i);
        myCounterCreationData[i] = new CounterCreationData();
