SoapAttributeAttribute.DataType 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定 XmlSerializer 所產生之 SOAP 屬性的 XML 結構描述定義語言 (XSD) 資料型別。
public:
property System::String ^ DataType { System::String ^ get(); void set(System::String ^ value); };public string DataType { get; set; }member this.DataType : string with get, setPublic Property DataType As String屬性值
XML 架構資料類型。
例外狀況
您指定的 XML 結構描述資料型別無法對應至 .NET 資料型別。
範例
下列範例會序列化類別，其中包含套用 的 SoapAttributeAttribute 數個欄位。 屬性 DataType 是針對 GroupNumber 和 Today 欄位設定的。

備註
下表列出具有 their.NET 對等專案的 XML 架構單一資料型別。
對於 XML 架構 base64Binary 和資料類型，請使用 結構的陣列 Byte ，並視情況將 設定為 「base64Binary」 或 「hexBinary」 套用 SoapAttributeAttributeDataType 。 hexBinary 對於 XML 架構 time 和資料類型，請使用 DateTime 型別，並將 設定為 「date」 或 「time」 的 套用 SoapAttributeAttributeDataType 。 date
針對對應至字串的每個 XML 架構資料類型，套用 SoapAttributeAttribute 其 DataType 屬性設定為 XML 架構資料類型的 。 請注意，這不會變更序列化格式，只會變更成員的架構。
注意
屬性會區分大小寫，因此您必須將它完全設定為其中一個 XML 架構資料類型。
注意
將二進位資料當做 XML 元素傳遞會更有效率，然後將它當做 XML 屬性傳遞。
如需 XML 架構資料類型的詳細資訊，請參閱名為 XML 架構第 2 部分：資料類型的萬維協會檔 (https://www.w3.org/TR/xmlschema-2/) 。
