설명
이 형식의 인스턴스가 serialize될 수 있음을 나타내도록 형식에 SerializableAttribute 특성을 적용합니다. 공용 언어 런타임은 serialize되고 있는 개체 그래프의 형식 중에 SerializableAttribute 특성이 적용되지 않은 형식이 있으면 SerializationException을 throw합니다.
또한 해당 클래스가 ISerializable 인터페이스를 구현하여 serialization 프로세스를 제어하는 경우에도 SerializableAttribute 특성을 적용합니다.
SerializableAttribute로 표시된 형식이 ISerializable 인터페이스를 구현하여 serialization 프로세스를 재정의하지 않는 한, 해당 형식의 모든 public 및 private 필드는 기본적으로 serialize됩니다. 기본 serialization 프로세스에서는 NonSerializedAttribute 특성으로 표시되는 필드를 제외합니다. 포인터, 핸들 또는 특정 환경에 고유하게 적용되며 다른 환경에서 의미 있게 재구성될 수 없는 다른 데이터 구조가 serialize할 수 있는 형식의 필드에 포함된 경우, 해당 필드에 NonSerializedAttribute 특성을 적용할 수도 있습니다.
특성 사용에 대한 자세한 내용은 특성을 사용하여 메타데이터 확장을 참조하십시오. Serialization에 대한 자세한 내용은 System.Runtime.Serialization을 참조하십시오.
예제
다음 예제에서는 SerializableAttribute 특성으로 표시된 개체의 serialization을 보여 줍니다. SoapFormatter 대신 BinaryFormatter를 사용하려면 적절한 줄의 주석 처리를 제거합니다.
