InstanceDataCollectionCollection Class

Provides a strongly typed collection of InstanceDataCollection objects.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public ref class InstanceDataCollectionCollection : public DictionaryBase

The InstanceDataCollectionCollection class represents the collection returned from the ReadCategory method. This collection contains all the counter and instance data. The collection contains an InstanceDataCollection object for each counter. Each 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.

The following code example displays the instance data for a particular PerformanceCounterCategory on the local computer. It first displays a numbered list of PerformanceCounterCategory names. After the user enters the number of one of the categories, the example gets the InstanceDataCollectionCollection for that PerformanceCounterCategory. It then converts the collection returned by the Values property to an array of InstanceDataCollection objects. The example displays the instance data associated with each InstanceData of each InstanceDataCollection.

No code example is currently available or this language may not be supported.
