Examples

다음 예제에서는 SerializableAttribute 특성으로 표시 된 개체의 serialization을 보여 줍니다.The following example demonstrates serialization of an object that is marked with the SerializableAttribute attribute. SoapFormatter대신 BinaryFormatter를 사용 하려면 적절 한 줄의 주석 처리를 제거 합니다.To use the BinaryFormatter instead of the SoapFormatter, uncomment the appropriate lines.

Remarks

형식에 SerializableAttribute 특성을 적용하여 이 형식의 인스턴스를 직렬화할 수 있음을 나타냅니다.Apply the SerializableAttribute attribute to a type to indicate that instances of this type can be serialized. Serialize 되는 개체 그래프의 형식에 SerializableAttribute 특성이 적용 되지 않은 경우 공용 언어 런타임에서 SerializationException을 throw 합니다.The common language runtime throws SerializationException if any type in the graph of objects being serialized does not have the SerializableAttribute attribute applied.

클래스가 ISerializable 인터페이스를 구현 하 여 serialization 프로세스를 제어 하는 경우에도 SerializableAttribute 특성을 적용 합니다.Apply the SerializableAttribute attribute even if the class also implements the ISerializable interface to control the serialization process.

형식에 SerializableAttribute 특성을 적용 하면 기본적으로 모든 private 및 public 필드가 serialize 됩니다.When you apply the SerializableAttribute attribute to a type, all private and public fields are serialized by default. Serialization 프로세스를 재정의 하는 ISerializable 인터페이스를 구현 하 여 serialization 추가 세부적으로를 제어할 수 있습니다.You can control serialization more granularly by implementing the ISerializable interface to override the serialization process.

또는 필드에 NonSerializedAttribute 특성을 적용 하 여 serialization에서 필드를 제외할 수 있습니다.Or you can exclude fields from serialization by applying the NonSerializedAttribute attribute to the field. Serialize 할 수 있는 형식의 필드에 특정 환경에 해당 하는 포인터, 핸들 또는 다른 데이터 구조가 포함 되어 있고 다른 환경에서 의미 없는 다시 구성 경우 해당 필드에 NonSerializedAttribute 특성을 적용 하는 것이 좋습니다.If a field of a serializable type contains a pointer, a handle, or some other data structure that is specific to a particular environment, and cannot be meaningfully reconstituted in a different environment, then you might want to apply the NonSerializedAttribute attribute to that field.

특성을 사용 하는 방법에 대 한 자세한 내용은 참조 하세요. 특성합니다.For more information about using attributes, see Attributes. Serialization에 대 한 자세한 내용은 System.Runtime.Serialization를 참조 하세요.For more information about serialization, see System.Runtime.Serialization.
