Comentarios

El Serialize método convierte los campos públicos y las propiedades de lectura y escritura de un objeto en XML. No convierte métodos, indexadores, campos privados ni propiedades de solo lectura.

En el xmlWriter parámetro , especifique un objeto que derive de la clase abstracta XmlWriter . XmlTextWriter deriva de XmlWriter.

El parámetro id proporciona la cadena base utilizada para crear identificadores SOAP. De forma predeterminada, estos son "id1", "id2" y así sucesivamente. Pero si el parámetro se establece en "myBase", los valores generados son "myBaseid1", "myBaseid2" y así sucesivamente. Esta funcionalidad se usa para crear valores de identificador únicos en todo el mensaje SOAP.

Utilice el xmlWriter parámetro para especificar un objeto que deriva de la clase abstracta XmlWriter , que está diseñada para escribir documentos XML. XmlTextWriter deriva de XmlWriter.

Establezca el encodingStyle parámetro en "http://schemas.xmlsoap.org/soap/encoding/" para la codificación SOAP versión 1.1; de lo contrario, establézcalo en "http://www.w3.org/2001/12/soap-encoding" para la codificación soap versión 1.2.

El Serialize método convierte los campos públicos y las propiedades de lectura y escritura de un objeto en XML. No convierte métodos, indexadores, campos privados ni propiedades de solo lectura.

En el textWriter parámetro , especifique un objeto que derive de la clase abstracta TextWriter . Las clases que derivan de TextWriter incluyen:

Cuando se invoca el Serialize método, los campos públicos y las propiedades de lectura y escritura de un objeto se convierten en XML. Los métodos, los indexadores, los campos privados y las propiedades de solo lectura no se serializan.

Use el stream parámetro para especificar un objeto que deriva de la clase abstracta Stream , que está diseñada para escribir en secuencias. Las clases que derivan de la Stream clase incluyen:

• BufferedStream

• FileStream

• MemoryStream

• NetworkStream
