Örnekler

Aşağıdaki kod örneği, yerel bilgisayardaki belirli InstanceData bir bilgisayarda bulunan nesnelerin içeriğini PerformanceCounterCategory görüntüler. İlk olarak, numaralandırılmış bir kategori listesi PerformanceCounter görüntüler. Kullanıcı kategorilerden birinin sayısını girdikten sonra, örnek içindeki her PerformanceCounterPerformanceCounterCategorybiri için öğesinin her örneğiyle PerformanceCounterilişkilendirilmiş örnek verilerini görüntüler.
