Namespace:
System.Xml.Serialization

Controla o esquema gerado pelo XmlSerializer quando uma instância da classe é serializada como XML codificado em SOAP.

Exemplos

O exemplo a seguir serializa uma classe chamada Group. Ela SoapTypeAttribute é aplicada à classe, com o TypeName conjunto como "SoapGroupType". O SoapTypeAttribute também é substituído, alterando a TypeName para "Equipe". Ambas as versões são serializadas, resultando em dois arquivos: SoapType.xml e SoapType2.xml.

Comentários

A SoapTypeAttribute classe pertence a uma família de atributos que controla como o XmlSerializer serializa ou desserializa um objeto como SOAP XML codificado. O XML resultante está em conformidade com a seção 5 do documento do World Wide Web Consortium, SOAP (Simple Object Access Protocol) 1.1. Para obter uma lista completa de atributos semelhantes, consulte Atributos que controlam a serialização SOAP codificada.

Para serializar um objeto como uma mensagem SOAP codificada, construa o XmlSerializer uso de um XmlTypeMapping método criado com o ImportTypeMapping método da SoapReflectionImporter classe.

O SoapTypeAttribute somente pode ser aplicado a declarações de classe.

A IncludeInSchema propriedade determina se o tipo de elemento XML resultante está incluído no documento de esquema XML (.xsd) para o fluxo XML gerado. Para ver o esquema, compile a classe em um arquivo DLL. Passe o arquivo resultante como um argumento para a Ferramenta de Definição de Esquema XML (Xsd.exe). A ferramenta gera o esquema XML para o fluxo XML gerado quando a classe é serializada por uma instância da XmlSerializer classe.

Definir um namespace diferente faz com que Xsd.exe escreva um arquivo de esquema diferente (.xsd) para o fluxo XML gerado quando a classe é serializada.

Construtores

SoapTypeAttribute()

Inicializa uma nova instância da classe SoapTypeAttribute.
SoapTypeAttribute(String)

Inicializa uma nova instância da classe SoapTypeAttribute e especifica o nome do tipo XML.
SoapTypeAttribute(String, String)

Inicializa uma nova instância da classe SoapTypeAttribute e especifica o nome e o namespace de XML do tipo.

Propriedades

IncludeInSchema

Obtém ou define um valor que indica se deve incluir o tipo nos documentos de esquema XML de codificação SOAP.
Namespace

Obtém ou define o namespace do tipo XML.
TypeId

Quando implementado em uma classe derivada, obtém um identificador exclusivo para este Attribute.

(Herdado de Attribute)
TypeName

Obtém ou define o nome do tipo XML.

Métodos

Equals(Object)

Retorna um valor que indica se essa instância é igual a um objeto especificado.

(Herdado de Attribute)
GetHashCode()

Retorna o código hash para a instância.

(Herdado de Attribute)
GetType()

Obtém o Type da instância atual.

(Herdado de Object)
IsDefaultAttribute()

Quando substituído em uma classe derivada, indica se o valor dessa instância é o valor padrão para a classe derivada.

(Herdado de Attribute)
Match(Object)

Quando substituído em uma classe derivada, retorna um valor que indica se essa instância é igual a um objeto especificado.

(Herdado de Attribute)
MemberwiseClone()

Cria uma cópia superficial do Object atual.

(Herdado de Object)
ToString()

Retorna uma cadeia de caracteres que representa o objeto atual.

(Herdado de Object)

Implantações explícitas de interface

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Mapeia um conjunto de nomes para um conjunto correspondente de identificadores de expedição.

(Herdado de Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Recupera as informações de tipo para um objeto, que pode ser usado para obter as informações de tipo para uma interface.

(Herdado de Attribute)
_Attribute.GetTypeInfoCount(UInt32)

Retorna o número de interfaces de informações do tipo que um objeto fornece (0 ou 1).

(Herdado de Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Fornece acesso a propriedades e métodos expostos por um objeto.

(Herdado de Attribute)

Aplica-se a
