Para que la deserialización se realice correctamente, la posición actual en la secuencia debe estar al principio del gráfico de objetos.For successful deserialization, the current position in the stream must be at the beginning of the object graph.

Los encabezados solo se usan para aplicaciones remotas específicas.Headers are used only for specific remoting applications. El HeaderHandler parámetro es una de las dos formas de devolver encabezados de una secuencia en formato RPC (llamada a procedimiento remoto) SOAP.The HeaderHandler parameter is one of two ways to return headers from a stream in SOAP Remote Procedure Call (RPC) format. La otra forma es usar la TopObject propiedad.The other way is to use the TopObject property.
