The System.Diagnostics.InstanceDataCollectionCollection class represents the collection returned from the PerformanceCounterCategory.ReadCategory method. This collection contains all the counter and instance data. The collection contains an System.Diagnostics.InstanceDataCollection object for each counter. Each System.Diagnostics.InstanceDataCollection object contains the performance data for all counters for that instance. Thus, the data is indexed by counter name and then by instance name.
