Ejemplos

El ejemplo siguiente muestra la serialización de un objeto que está marcado con el SerializableAttribute atributo.The following example demonstrates serialization of an object that is marked with the SerializableAttribute attribute. Para usar el BinaryFormatter en lugar de la SoapFormatter, quite las líneas correspondientes.To use the BinaryFormatter instead of the SoapFormatter, uncomment the appropriate lines.

Aplique el atributo SerializableAttribute a un tipo para indicar que se pueden serializar instancias de este tipo.Apply the SerializableAttribute attribute to a type to indicate that instances of this type can be serialized. Common language runtime produce SerializationException si cualquier tipo en el gráfico de objetos que se está serializando no tiene el SerializableAttribute atributo aplicado.The common language runtime throws SerializationException if any type in the graph of objects being serialized does not have the SerializableAttribute attribute applied.

Aplicar el SerializableAttribute atributo incluso si la clase también implementa el ISerializable interfaz para controlar el proceso de serialización.Apply the SerializableAttribute attribute even if the class also implements the ISerializable interface to control the serialization process.

Al aplicar el SerializableAttribute atributo a un tipo, se serializan todos los campos públicos y privados de forma predeterminada.When you apply the SerializableAttribute attribute to a type, all private and public fields are serialized by default. Puede controlar serialización más detallado mediante la implementación de la ISerializable interfaz para invalidar el proceso de serialización.You can control serialization more granularly by implementing the ISerializable interface to override the serialization process.

O puede excluir los campos de la serialización aplicando el NonSerializedAttribute al campo de atributo.Or you can exclude fields from serialization by applying the NonSerializedAttribute attribute to the field. Si un campo de un tipo serializable contiene un puntero, un identificador o alguna otra estructura de datos que es específico para un entorno concreto y no se puede reconstituir correctamente en un entorno diferente, es posible que desee aplicar el NonSerializedAttribute atributo en ese campo.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.
