Я пытаюсь изменить PerformanceCounter, который я создал на C#. Но, похоже, это не меняется. Этот счетчик должен быть фактическим, чтобы быть флагом: 0 или 1.PerformanceCounter RawValue не изменен modified
Я взял следующий код из сети. Он создал коллекционную категорию вместе с счетчиками. Но RawValue всегда показывает 0!
Я работаю над Win7/64.
Можете ли вы посоветовать?
