Salve ragazzi sto provando a inserire dentro una barra 4 dati : utilizzo corrente di un processo la quantità CPU,RAM,DISCO,RETE utilizzata .. ma aprendo il task-manager leggo percentuali ben diverse ... sto utilizzando using System.Diagnostics; ma sembra dare dati completamente a caso .. qualcuno cosce la soluzione a questo problema ? ho fatto molti test come potete vedere dal codice

Ma il task manager non è affatto preciso. Lo strumento più preciso è appunto PerformanceCounter. Se usi perfmon.exe e setti un contatore, oppure se usi process explorer, vedrai che i numeri sono gli stessi di PerformanceCounter.
