SoapAttributeAttribute.DataType Proprietà
Definizione
Importante
Alcune informazioni sono relative alla release non definitiva del prodotto, che potrebbe subire modifiche significative prima della release definitiva. Microsoft non riconosce alcuna garanzia, espressa o implicita, in merito alle informazioni qui fornite.
Ottiene o imposta il tipo di dati XSD (XML Schema Definition Language) dell'attributo SOAP generato mediante la classe XmlSerializer.
public:
property System::String ^ DataType { System::String ^ get(); void set(System::String ^ value); };
public string DataType { get; set; }
member this.DataType : string with get, set
Public Property DataType As String
Valore della proprietà
Tipo di dati XML Schema.
Eccezioni
Non è possibile eseguire il mapping del tipo di dati XML Schema al tipo di dati .NET.
Esempio
Nell'esempio seguente viene serializzata una classe che contiene diversi campi a cui viene applicato un oggetto SoapAttributeAttribute . La DataType proprietà viene impostata per i GroupNumber
campi e Today
.

Commenti
Nella tabella seguente sono elencati i tipi di dati semplici di XML Schema con their.NET equivalenti.
Per xml Schema base64Binary
e hexBinary
tipi di dati, usare una matrice di Byte strutture e applicare un SoapAttributeAttribute oggetto con l'oggetto DataType impostato su "base64Binary" o "hexBinary", a seconda delle esigenze. Per xml Schema time
e date
tipi di dati, usare il DateTime tipo e applicare con SoapAttributeAttribute il DataType valore impostato su "date" o "time".
Per ogni tipo di dati XML Schema mappato a una stringa, applicare con la SoapAttributeAttribute relativa DataType proprietà impostata sul tipo di dati XML Schema. Si noti che questo non modifica il formato di serializzazione, ma solo lo schema per il membro.
Nota
La proprietà fa distinzione tra maiuscole e minuscole, pertanto è necessario impostarla esattamente su uno dei tipi di dati XML Schema.
Nota
Il passaggio di dati binari come elemento XML è più efficiente e quindi passarlo come attributo XML.
