O seguinte exemplo de código cria um PerformanceCounterCategory com o PerformanceCounterCategory() construtor. Solicita ao utilizador os PerformanceCounterCategory nomes dos computadores e depois define as CategoryName propriedades e MachineName a partir dos valores introduzidos. De seguida, apresenta os valores das CategoryNamepropriedades , MachineName, e CategoryHelp , ou apresenta uma mensagem de erro se não PerformanceCounterCategory for possível aceder a .
