इस वर्ग तो उपयोग करने के लिए भ्रामक है! उन्होंने इतने सारे जटिल पात्रों से युक्त तारों के बजाय enums का उपयोग क्यों नहीं किया! – TheGateKeeper
मेरा अनुमान है कि यह इस तथ्य पर आधारित है कि प्रत्येक उत्पाद टीम (विंडोज़, आईआईएस, आदि) काउंटर नामों का "मालिक" है इसलिए वे किसी भी समय किसी भी नाम को जोड़/हटा/बदल सकते हैं। इस तरह से हम सभी काउंटरों का अपना सेट बना सकते हैं। – CriGoT
मुझे कस्टम डेटा की निगरानी करने के लिए काउंटर बनाने में कोई बिंदु नहीं दिखता है, आप इसे प्रोग्रामेटिक रूप से कर सकते हैं। – TheGateKeeper
