Ejemplos

En el ejemplo siguiente se serializa una clase denominada Group. SoapTypeAttribute se aplica a la clase , con el TypeName establecido en "SoapGroupType". SoapTypeAttribute También se invalida, cambiando a TypeName "Team". Ambas versiones se serializan, lo que da lugar a dos archivos: SoapType.xml y SoapType2.xml.

Comentarios

La SoapTypeAttribute clase pertenece a una familia de atributos que controla cómo serializa XmlSerializer o deserializa un objeto como XML SOAP codificado. El XML resultante se ajusta a la sección 5 del documento World Wide Web Consortium, Protocolo simple de acceso a objetos (SOAP) 1.1. Para obtener una lista completa de atributos similares, vea Atributos que controlan la serialización SOAP codificada.

Para serializar un objeto como un mensaje SOAP codificado, construya mediante XmlSerializer un XmlTypeMapping objeto creado con el ImportTypeMapping método de la SoapReflectionImporter clase .

Solo SoapTypeAttribute se puede aplicar a las declaraciones de clase.

La IncludeInSchema propiedad determina si el tipo de elemento XML resultante se incluye en el documento de esquema XML (.xsd) para la secuencia XML generada. Para ver el esquema, compile la clase en un archivo DLL. Pase el archivo resultante como argumento a la Herramienta de definición de esquemas XML (Xsd.exe). La herramienta genera el esquema XML para la secuencia XML generada cuando una instancia de la clase serializa la XmlSerializer clase .

Establecer un espacio de nombres diferente hace que Xsd.exe escriba un archivo de esquema (.xsd) diferente para la secuencia XML generada cuando se serializa la clase.
