    {
        try
        {

            string myCategoryName;
            int numberOfCounters;
            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);
            Console.Write("Enter the category Name : ");
            myCategoryName = Console.ReadLine();
            // Check if the category already exists or not.
            if (!PerformanceCounterCategory.Exists(myCategoryName))

                   new CounterCreationDataCollection();
                // Add the 'CounterCreationDataCollection' to 'CounterCreationDataCollection' object.
                myNewCounterCollection.AddRange(myCounterCollection);

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

                Console.WriteLine("The list of counters in CounterCollection are: ");
                for (int i = 0; i < myNewCounterCollection.Count; i++)
                    Console.WriteLine("Counter {0} is '{1}'", i + 1, myNewCounterCollection[i].CounterName);
            }
            else
            {
                Console.WriteLine("The category already exists");
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception: {0}.", e.Message);
