Exemplos

O exemplo seguinte serializa uma classe chamada Group. O SoapTypeAttribute é aplicado à classe com TypeName o conjunto como "SoapGroupType". O SoapTypeAttribute também é sobreposto, mudando para TypeName "Equipa". Ambas as versões são serializadas, resultando em dois ficheiros: SoapType.xml e SoapType2.xml.

Observações

Se definir um Namespace valor para mais do que um tipo (ou seja, se aplicar o atributo a mais do que uma classe com um valor diferente Namespace para cada uma), a Ferramenta de Definição de Esquema XML (Xsd.exe) gera um ficheiro de esquema separado (.xsd) para cada tipo. Isto porque definir um namespace diferente para cada tipo torna cada tipo distinto dos outros, o que torna necessário que cada tipo seja escrito como uma entidade independente.
