Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.PerformanceCounter.dll

Source:

CounterCreationDataCollection.cs

Returns the index of a CounterCreationData object in the collection.

public:
 int IndexOf(System::Diagnostics::CounterCreationData ^ value);

public int IndexOf (System.Diagnostics.CounterCreationData value);

member this.IndexOf : System.Diagnostics.CounterCreationData -> int

Public Function IndexOf (value As CounterCreationData) As Integer

Parameters

value

CounterCreationData

The CounterCreationData object to locate in the collection.

Returns

Int32

The zero-based index of the specified CounterCreationData, if it is found, in the collection; otherwise, -1.

Examples

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

// Check if the category already exists or not.

   Console::Write( "Enter the number of counters : " );
   numberOfCounters = Int32::Parse( Console::ReadLine() );
   array<CounterCreationData^>^ myCounterCreationData =
      gcnew array<CounterCreationData^>(numberOfCounters);

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