Returns

Int32

Examples

The following example retrieves CounterCreationData entries from a CounterCreationDataCollection and uses the IndexOf method to display their names and indexes.

C#

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();
        myCounterCreationData[i].CounterName = Console.ReadLine();
    }
    CounterCreationDataCollection myCounterCollection =
       new CounterCreationDataCollection(myCounterCreationData);
    CounterCreationData myInsertCounterCreationData = new CounterCreationData(
       "CounterInsert", "", PerformanceCounterType.NumberOfItems32);
    // Insert an instance of 'CounterCreationData' in the 'CounterCreationDataCollection'.
    myCounterCollection.Insert(myCounterCollection.Count - 1,
       myInsertCounterCreationData);
    Console.WriteLine("'{0}' counter is inserted into 'CounterCreationDataCollection'",
       myInsertCounterCreationData.CounterName);
    // Create the category.
    PerformanceCounterCategory.Create(myCategoryName, "Sample Category",
    PerformanceCounterCategoryType.SingleInstance, myCounterCollection);

    for (int i = 0; i < numberOfCounters; i++)
    {
        myCounter = new PerformanceCounter(myCategoryName,
           myCounterCreationData[i].CounterName, "", false);
    }
    Console.WriteLine("The index of '{0}' counter is {1}",
       myInsertCounterCreationData.CounterName, myCounterCollection.IndexOf(myInsertCounterCreationData));
}
else
{
    Console.WriteLine("The category already exists");
}
