Exemplos

O exemplo de código seguinte apresenta os dados de instância de um determinado PerformanceCounterCategory no computador local. Primeiro apresenta uma lista numerada de PerformanceCounterCategory nomes. Depois de o utilizador introduzir o número de uma das categorias, o exemplo obtém o InstanceDataCollectionCollection para que PerformanceCounterCategory. Depois, converte a coleção devolvida pela Values propriedade num array de InstanceDataCollection objetos. O exemplo mostra os dados das instâncias associados a cada InstanceDataInstanceDataCollectionum de cada .

Observações

A InstanceDataCollectionCollection classe representa a coleção devolvida pelo ReadCategory método. Esta coleção contém todos os dados de contadores e instâncias. A coleção contém um InstanceDataCollection objeto para cada contador. Cada InstanceDataCollection objeto contém os dados de desempenho de todos os contadores dessa instância. Assim, os dados são indexados pelo nome do contador e depois pelo nome da instância.
