निम्नलिखित एक्सटेंशन तरीकों कि मैं पैदा की है, तो आप सेट या भले ही वे

या सेट
SetPropertyValue (customObject, "Property.Nested.Child।। नाम "," मेरी मनपसंद नाम ");

आशा है कि आप इसे उपयोगी पाते
यह विफल रहता है क्योंकि आपने memberinfo ऑब्जेक्ट पर संपत्ति का नाम सेट करने का प्रयास किया था। सदस्य की जानकारी का नाम है, लेकिन यह [_person] का नाम नहीं है। –
