To answer this question, we need to understand the concept of reading metadata and using its contents in .NET.
Option A) Reflection - This option is correct. Reflection in .NET refers to the process of examining and manipulating metadata, such as types, properties, and methods, at runtime. It allows you to dynamically inspect and interact with objects and their metadata. Reflection is often used for tasks like invoking methods, accessing properties, and creating instances dynamically.
Option B) Enumeration - This option is incorrect. Enumeration is a different concept in .NET that refers to the process of iterating over a collection of items.
Option C) Binding - This option is incorrect. Binding in .NET refers to the process of connecting data to a user interface element or a property of an object.
Option D) Serialization - This option is incorrect. Serialization in .NET refers to the process of converting an object into a format that can be stored or transmitted, typically as binary or XML data.
The correct answer is A) Reflection. This option is correct because reflection is the operation of reading metadata and using its contents in .NET.
