The ISerializable type exposes the following members.
Methods
Remarks
Any class that might be serialized must be marked with the SerializableAttribute. If a class needs to control its serialization process, it can implement the ISerializable interface. The Formatter calls the GetObjectData at serialization time and populates the supplied SerializationInfo with all the data required to represent the object. The Formatter creates a SerializationInfo with the type of the object in the graph. Objects that need to send proxies for themselves can use the FullTypeName and AssemblyName methods on SerializationInfo to change the transmitted information. In the case of class inheritance, it is possible to serialize a class that derives from a base class that implements ISerializable. In this case, the derived class should call the base class implementation of GetObjectData inside its implementation of GetObjectData. Otherwise, the data from the base class will not be serialized. The ISerializable interface implies a constructor with the signature constructor (SerializationInfo information, StreamingContext context). At deserialization time, the current constructor is called only after the data in the SerializationInfo has been deserialized by the formatter. In general, this constructor should be protected if the class is not sealed. The order in which objects are deserialized cannot be guaranteed. For example, if one type references a type that has not been deserialized yet, an exception will occur. If you are creating types that have such dependencies, you can work around the problem by implementing the IDeserializationCallback interface and the OnDeserialization method. The serialization architecture handles object types that extend MarshalByRefObject the same as types that extend Object. These types can be marked with the SerializableAttribute and implement the ISerializable interface as any other object type. Their object state will be captured and persisted onto the stream. When these types are being used through System.Runtime.Remoting, the remoting infrastructure provides a surrogate that preempts typical serialization and instead serializes a proxy to the MarshalByRefObject. A surrogate is a helper that knows how to serialize and deserialize objects of a particular type. The proxy, invisible to the user in most cases, will be of type ObjRef. As a general design pattern, it would be unusual for a class to be both marked with the serializable attribute and extend MarshalByRefObject. Developers should think carefully about the possible serialization and remoting scenarios when combining these two characteristics. One example where this might be applicable is with a MemoryStream. While the base class of MemoryStream (Stream) extends from MarshalByRefObject, it is possible to capture the state of a MemoryStream and restore it at will. It might, therefore, be meaningful to serialize the state of this stream into a database and restore it at some later point in time. However, when used through remoting, an object of this type would be proxied. For more information about serialization of classes that extend MarshalByRefObject, see RemotingSurrogateSelector. For more information about implementing ISerializable, see [<topic://cpconCustomSerialization>]. Notes to ImplementersImplement this interface to allow an object to take part in its own serialization and deserialization.

Métodos
Comentarios
Cualquier clase que tenga posibilidades de serializarse debe marcarse con SerializableAttribute. Si una clase necesita controlar su proceso de serialización, puede implementar la interfaz ISerializable. Formatter llama al método GetObjectData en el momento de la serialización y llena el objeto SerializationInfo suministrado con todos los datos necesarios para representar el objeto. Formatter crea un objeto SerializationInfo con el tipo del objeto del gráfico. Los objetos que necesitan enviar proxies para ellos mismos pueden utilizar FullTypeName y AssemblyName en el objeto SerializationInfo para cambiar la información transmitida. En el caso de herencia de clases, se puede serializar una clase derivada de una clase base que implementa ISerializable. En este caso, la clase derivada debe llamar a la implementación de la clase base de GetObjectData en su implementación de GetObjectData. De lo contrario, no se serializarán los datos de la clase base. La interfaz ISerializable implica un constructor con la firma constructor (información SerializationInfo, contexto StreamingContext). En el momento de la deserialización, se llama al constructor actual sólo después de que el formateador haya deserializado los datos de SerializationInfo. En general, este constructor debe protegerse si la clase no es de tipo sealed. No se puede garantizar el orden en el que se deserializan los objetos. Por ejemplo, si un tipo hace referencia a otro que no se ha deserializado todavía, se producirá una excepción. Si crea tipos que tienen tales dependencias, puede solucionar el problema implementando la interfaz IDeserializationCallback y el método OnDeserialization. La arquitectura de serialización controla tipos de objetos que extienden MarshalByRefObject al igual que tipos que extienden Object. Estos tipos se pueden marcar con SerializableAttribute e implementan la interfaz ISerializable como cualquier otro tipo de objeto. Su estado de objeto se capturará y persistirá en la secuencia. Cuando estos tipos se utilizan a través de System.Runtime.Remoting, la infraestructura de comunicación remota proporciona un suplente que anticipa la serialización típica y, en su lugar, serializa un proxy para MarshalByRefObject. Un suplente es un elemento auxiliar que sabe cómo serializar y deserializar objetos de un tipo concreto. El proxy, invisible para el usuario en la mayoría de los casos, será de tipo ObjRef. Como modelo de diseño general, sería poco habitual que una clase se marcase con el atributo "serializable" y extendiese MarshalByRefObject. Los programadores deben detenerse a pensar sobre los posibles escenarios de serialización y comunicación remota al combinar estas dos características. Un caso en el que esto sería aplicable se da con MemoryStream. Mientras que la clase base de MemoryStream (Stream) se extiende desde MarshalByRefObject, es posible capturar el estado de un objeto MemoryStream y restaurarlo como se desee. Por tanto, podría tener sentido serializar el estado de esta secuencia en una base de datos y restaurarla más adelante. No obstante, si se utiliza un objeto de este tipo a través de una comunicación remota, se utilizaría un proxy. Para obtener más información sobre la serialización de clases que extienden MarshalByRefObject, vea RemotingSurrogateSelector. Para obtener más información sobre la implementación de ISerializable, vea [<topic://cpconCustomSerialization>]. Notas para los implementadoresImplemente esta interfaz para permitir que un objeto participe en su propia serialización y deserialización.
