Comentários
Essa classe destina-se a ser uma implementação leve de um modelo de objeto XML simples para uso dentro do sistema de segurança e não para uso como um modelo de objeto XML geral. Esta documentação pressupõe um conhecimento básico do XML.
O modelo de objeto XML simples para um elemento consiste nas seguintes partes:
A marca é o nome do elemento.
Os atributos são zero ou mais pares de atributo de nome/valor no elemento .
Os filhos são zero ou mais elementos aninhados dentro
<tag>
de e</tag>
.
É altamente sugerido que a representação XML baseada em atributo seja usada para expressar elementos de segurança e seus valores. Isso significa que as propriedades de um elemento são expressas como atributos e valores de propriedade são expressos como valores de atributo. Evite aninhar texto dentro de marcas. Para qualquer <tag>text</tag>
representação, uma representação do tipo <tag value="text"/>
geralmente está disponível. O uso dessa representação XML baseada em atributo aumenta a legibilidade e permite uma portabilidade WMI fácil da serialização de XML resultante.
Um nome de atributo deve ser um caractere ou mais e não pode ser null
. Se a representação de valor baseada em elemento for usada, elementos com uma cadeia de caracteres de texto representada null
no formulário; caso contrário, o <tag/>
texto será delimitado pelos <tag>
tokens e </tag>
. Ambos os formulários podem ser combinados com atributos, que são mostrados se estiverem presentes.
As marcas, atributos e texto de elementos, se presentes, sempre diferenciam maiúsculas de minúsculas. O formulário XML contém aspas e escapes quando necessário. Valores de cadeia de caracteres que incluem caracteres inválidos para uso em XML resultam em um ArgumentException. Essas regras se aplicam a todas as propriedades e métodos.
Observação
Por motivos de desempenho, a validade do caractere só é verificada quando o elemento é codificado no formulário de texto XML e não em todos os conjuntos de uma propriedade ou método. Métodos estáticos permitem a verificação explícita quando necessário.
Construtores
SecurityElement(String) |
Inicializa uma nova instância da classe SecurityElement com a marca especificada. |
SecurityElement(String, String) |
Inicializa uma nova instância da classe SecurityElement com o texto e a marca especificados. |
Propriedades
Attributes |
Obtém ou define os atributos de um elemento XML como pares nome/valor. |
Children |
Obtém ou define a matriz de elementos filho do elemento XML. |
Tag |
Obtém ou define o nome da marca de um elemento XML. |
Text |
Obtém ou define o texto em um elemento XML. |
Métodos
AddAttribute(String, String) |
Adiciona um atributo de nome/valor a um elemento XML. |
AddChild(SecurityElement) |
Adiciona um elemento filho ao elemento XML. |
Attribute(String) |
Localiza um atributo pelo nome em um elemento XML. |
Copy() |
Cria e retorna uma cópia idêntica do objeto SecurityElement atual. |
Equal(SecurityElement) |
Compara dois objetos de elemento XML quanto à igualdade. |
Equals(Object) |
Determina se o objeto especificado é igual ao objeto atual. (Herdado de Object) |
Escape(String) |
Substitui os caracteres XML inválidos em uma cadeia de caracteres com seus equivalentes XML válidos. |
FromString(String) |
Cria um elemento de segurança de uma cadeia de caracteres codificada em XML. |
GetHashCode() |
Serve como a função de hash padrão. (Herdado de Object) |
GetType() |
Obtém o Type da instância atual. (Herdado de Object) |
IsValidAttributeName(String) |
Determina se uma cadeia de caracteres é um nome de atributo válido. |
IsValidAttributeValue(String) |
Determina se uma cadeia de caracteres é um valor de atributo válido. |
IsValidTag(String) |
Determina se uma cadeia de caracteres é uma marca válida. |
IsValidText(String) |
Determina se uma cadeia de caracteres é válida como texto dentro de um elemento XML. |
MemberwiseClone() |
Cria uma cópia superficial do Object atual. (Herdado de Object) |
SearchForChildByTag(String) |
Localiza um filho pelo seu nome de marca. |
SearchForTextOfTag(String) |
Localiza um filho pelo seu nome de marca e retorna o texto contido. |
ToString() |
Produz uma representação de cadeia de caracteres de um elemento XML e seus atributos constituintes, elementos filho e texto. |
