Ejemplos

En el ejemplo de código siguiente se muestran los datos de instancia de un determinado PerformanceCounterCategory en el equipo local. En primer lugar, muestra una lista numerada de PerformanceCounterCategory nombres. Después de que el usuario escriba el número de una de las categorías, el ejemplo obtiene para InstanceDataCollectionCollection ese PerformanceCounterCategoryobjeto . A continuación, convierte la colección devuelta por la Values propiedad en una matriz de InstanceDataCollection objetos . En el ejemplo se muestran los datos de instancia asociados a cada InstanceData uno de cada InstanceDataCollection.

Comentarios

La InstanceDataCollectionCollection clase representa la colección devuelta desde el ReadCategory método . Esta colección contiene todos los datos de contador e instancia. La colección contiene un InstanceDataCollection objeto para cada contador. Cada InstanceDataCollection objeto contiene los datos de rendimiento de todos los contadores de esa instancia. Por lo tanto, los datos se indexan por nombre de contador y, a continuación, por nombre de instancia.
