Step-by-Step Solution
Solution:
Step 1: Understand explicit interface implementation
Explicit interface methods are not accessible via class instance directly.Step 2: Use casting to interface type
Casting the instance to IY allows calling IY.Process() explicitly implemented method.Final Answer:
Cast the instance to IY and call Process() -> Option AQuick Check:
Explicit methods require interface cast to call [OK]
Quick Trick: Cast to interface to call explicit methods [OK]
Common Mistakes:
MISTAKES- Calling explicit methods directly on class instance
- Thinking reflection is needed
- Believing explicit methods are inaccessible
