SoapElementAttribute.DataType プロパティ

[アーティクル]
03/28/2008

生成された XML 要素の XML スキーマ定義言語 (XSD: XML Schema Definition Language) データ型を取得または設定します。

Public Property DataType As String
[C#]
public string DataType {get; set;}
[C++]
public: __property String* get_DataType();public: __property void set_DataType(String*);
[JScript]
public function get DataType() : String;public function set DataType(String);

プロパティ値

XML スキーマデータ型の 1 つ。

解説

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 SoapElementAttribute を適用します。XML スキーマの time データ型と date データ型については、 DateTime 型を使用して、 DataType を "date" または "time" に設定した SoapElementAttribute 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 スキーマ型に設定した SoapElementAttribute を適用します。これにより、メンバのスキーマだけが変更され、シリアル化形式は変更されなくなります。

メモこのプロパティでは大文字と小文字が区別されるため、XML スキーマデータ型を正しく設定する必要があります。

メモバイナリデータは、XML 属性として渡すよりも XML 要素として渡す方が効率的です。

XML データ型の詳細については、W3C (World Wide Web Consortium) (www.w3.org) のドキュメント『XML Schema Part 2: Datatypes』を参照してください。

使用例

[Visual Basic, C#, C++] Vehicle という名前のフィールドが含まれている Transportation という名前のクラスのインスタンスをシリアル化する例を次に示します。このフィールドには、 SoapElementAttribute が適用されています。このフィールドがシリアル化されると、その XML 要素名は "Vehicle" ではなく "Wheels" になります。 SerializeOverride メソッドは、 SoapElementAttribute を作成し、 SoapAttributes の SoapElement プロパティに、作成した SoapElementAttribute を設定します。この SoapAttributes が、 XmlTypeMapping を作成するために使用される SoapAttributeOverrides に追加されます。作成された XmlTypeMapping を使用して XmlSerializer が構築され、 Transportation クラスのインスタンスが再びシリアル化されます。 SoapElementAttribute を使用してシリアル化がオーバーライドされるため、生成された XML 要素の名前は "Wheels" ではなく "Truck" になります。
