Os tipos simples são definidos por derivação dos tipos simples existentes (tipos de dados internos e tipos simples derivados). Um tipo simples não pode conter elementos e não pode ter atributos.
Xml |
Inicializa uma nova instância da classe XmlSchemaSimpleType. |
Annotation |
Obtém ou define a propriedade |
Base |
Obsoleto.
Obsoleto.
Obsoleto.
Obtém o tipo de objeto pós-compilação ou o tipo de dados XSD (Linguagem de Definição de Esquema XML) interno, elemento simpleType ou elemento complexType. Esta é uma propriedade infoset pós-compilação do esquema. (Herdado de XmlSchemaType) |
Base |
Obtém o valor pós-compilação para o tipo base desse tipo de esquema. (Herdado de XmlSchemaType) |
Content |
Obtém ou define XmlSchemaSimpleTypeUnion, XmlSchemaSimpleTypeList ou XmlSchemaSimpleTypeRestriction. |
Datatype |
Obtém o valor de pós-compilação para o tipo de dados do tipo complexo. (Herdado de XmlSchemaType) |
Derived |
Obtém as informações pós-compilação sobre como esse elemento foi derivado de seu tipo base. (Herdado de XmlSchemaType) |
Final |
Obtém ou define o atributo final da derivação de tipo que indica se mais derivações são permitidas. (Herdado de XmlSchemaType) |
Final |
Obtém o valor de pós-compilação da propriedade Final. (Herdado de XmlSchemaType) |
Id |
Obtém ou define a ID de cadeia de caracteres. (Herdado de XmlSchemaAnnotated) |
Is |
Obtém ou define um valor que indica se esse tipo tem um modelo de conteúdo misto. Essa propriedade só é válida em um tipo complexo. (Herdado de XmlSchemaType) |
Line |
Obtém ou define o número de linha no arquivo ao qual o elemento |
Line |
Obtém ou define a posição da linha no arquivo ao qual o elemento |
Name |
Obtém ou define o nome do tipo. (Herdado de XmlSchemaType) |
Namespaces |
Obtém ou define o XmlSerializerNamespaces a ser usado com esse objeto de esquema. (Herdado de XmlSchemaObject) |
Parent |
Obtém ou define o pai deste XmlSchemaObject. (Herdado de XmlSchemaObject) |
Qualified |
Obtém o nome qualificado para o tipo construído com base no atributo |
Source |
Obtém ou define o local de origem para o arquivo que carregou o esquema. (Herdado de XmlSchemaObject) |
Type |
Obtém o XmlTypeCode do tipo. (Herdado de XmlSchemaType) |
Unhandled |
Obtém ou define os atributos qualificados que não pertencem ao namespace de destino do esquema atual. (Herdado de XmlSchemaAnnotated) |
Equals(Object) |
Determina se o objeto especificado é igual ao objeto atual. (Herdado de Object) |
Get |
Serve como a função de hash padrão. (Herdado de Object) |
Get |
Obtém o Type da instância atual. (Herdado de Object) |
Memberwise |
Cria uma cópia superficial do Object atual. (Herdado de Object) |
To |
Retorna uma cadeia de caracteres que representa o objeto atual. (Herdado de Object) |
