Serialization converts an object's state into a stream format (typically binary, XML, or JSON) that can be stored, transmitted, or reconstructed later. This is a fundamental concept in .NET for object persistence and data exchange.
Serialization is the process of converting an object's in-memory state into a sequential format (like bytes or XML) that can be written out to a stream — a file, network connection, or memory buffer — so it can be stored or transmitted and later reconstructed via deserialization. This is a foundational concept in most object-oriented platforms, so the statement is true.
