    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();
    // Add the 'CounterCreationData[]' to 'CounterCollection'.
    myCounterCollection.AddRange(myCounterCreationData);

    PerformanceCounterCategory.Create(myCategoryName,
       "Sample Category",
    PerformanceCounterCategoryType.SingleInstance, myCounterCollection);

    if (myCounterCreationData.Length > 0)
    {

        {
            myCounterCollection.Remove(myCounterCreationData[0]);
            Console.WriteLine("'{0}' counter is removed from the " +
