Comentarios

Esta clase se utiliza por objetos con el comportamiento de serialización personalizada.This class is used by objects with custom serialization behavior. El GetObjectData método cualquiera ISerializable o ISerializationSurrogate rellena el SerializationInfo almacenar con el nombre, tipo y valor de cada fragmento de información desea serializar.The GetObjectData method on either ISerializable or ISerializationSurrogate populates the SerializationInfo store with the name, type, and value of each piece of information it wants to serialize. Durante la deserialización, la función adecuada puede extraer esta información.During deserialization, the appropriate function can extract this information.

Se agregan objetos a la SerializationInfo almacenar en tiempo de serialización mediante el AddValue métodos y se extraen desde el SerializationInfo almacenar en la deserialización mediante el GetValue métodos.Objects are added to the SerializationInfo store at serialization time using the AddValue methods and extracted from the SerializationInfo store at deserialization using the GetValue methods.
