XmlTextAttribute.DataType プロパティ
アセンブリ: System.Xml (system.xml.dll 内)

Dim instance As XmlTextAttribute Dim value As String value = instance.DataType instance.DataType = value
/** @property */ public String get_DataType () /** @property */ public void set_DataType (String value)
W3C (World Wide Web Consortium) (www.w3.org ) のドキュメント『XML Schema Part 2: Datatypes』で定義されている XML スキーマ (XSD) データ型。


DataType プロパティに XML スキーマの単純データ型を設定すると、生成される XML の書式が影響を受けます。たとえば、このプロパティに "date" を設定すると、生成されるテキストの書式は汎用的な日付スタイル (2001-08-31 など) になります。それとは対照的に、このプロパティに "dateTime" を設定すると、ISO (International Organization for Standardization) のドキュメント 8601、『Representations of Dates and Times』で定義されているような、特定の瞬間を表す書式 (2001-08-15T06:59:11.0508456-07:00) になります。
DataType プロパティの設定による影響は、XML スキーマ定義ツール (Xsd.exe) を使用して、コンパイル済みファイル用の XML スキーマを生成する場合にも及びます。このツールの使用方法については、「XML スキーマ定義ツールと XML シリアル化」を参照してください。
XML スキーマの単純データ型と、それに相当する .NET データ型の表を次に示します。
XML スキーマの base64Binary データ型と hexBinary データ型については、Byte 構造体の配列を使用し、DataType をそれぞれ "base64Binary" または "hexBinary" に設定した XmlTextAttribute を適用します。XML スキーマの time データ型および date データ型については、DateTime 型を使用して、DataType が "date" または "time" に設定されている XmlTextAttribute を適用します。
文字列に割り当てられるすべての XML スキーマ データ型については、DataType プロパティをその XML スキーマ データ型に設定した XmlTextAttribute を適用します。ただし、これで変更されるのはメンバのスキーマだけであり、シリアル化形式は変更されません。
