Poznámky
Následující tabulka uvádí jednoduché datové typy schématu XML s their.NET ekvivalenty.
V případě schématu base64Binary
XML a hexBinary
datových Byte typů použijte pole struktur a podle potřeby použijte SoapAttributeAttribute DataType pole se sadou "base64Binary" nebo "hexBinary". U schématu time
XML a date
datových typů použijte DateTime typ a použijte SoapAttributeAttribute ho DataType se sadou na "datum" nebo "čas".
Pro každý datový typ schématu XML, který je mapován na řetězec, použijte SoapAttributeAttribute s jeho DataType vlastností nastavenou na datový typ schématu XML. Všimněte si, že se tím nezmění formát serializace, pouze schéma člena.
Poznámka
Vlastnost rozlišuje malá a velká písmena, takže ji musíte nastavit přesně na jeden z datových typů schématu XML.
Poznámka
Předávání binárních dat jako elementu XML je efektivnější a pak je předává jako atribut XML.
Další informace o datových typech schémat XML naleznete v dokumentu konsorcia World Wide Consortium s názvem XML Schema Part 2: Datatypes](https://www.w3.org/TR/xmlschema-2/).
