Esempi

Nell'esempio PerformanceCounterCategory PerformanceCounterCategory()di codice seguente viene creato un oggetto con.The following code example creates a PerformanceCounterCategory with the PerformanceCounterCategory(). Richiede all'utente PerformanceCounterCategory i nomi dei computer e, quindi imposta le CategoryName proprietà e MachineName dai valori immessi.It prompts the user for the PerformanceCounterCategory and computer names, then sets the CategoryName and MachineName properties from the entered values. Visualizza quindi i valori delle CategoryNameproprietà, MachineNamee CategoryHelp , PerformanceCounterCategory oppure Visualizza un messaggio di errore se non è possibile accedervi.It then displays the values of the CategoryName, MachineName, and CategoryHelp properties, or it displays an error message if the PerformanceCounterCategory cannot be accessed.

public static void Main(string[] args)
