XmlAttributes.XmlType プロパティ
XmlTypeAttribute が適用されているクラスを XmlSerializer がシリアル化する方法を指定するオブジェクトを取得または指定します。
Public Property XmlType As XmlTypeAttribute
[C#]
public XmlTypeAttribute XmlType {get; set;}
[C++]
public: __property XmlTypeAttribute* get_XmlType();public: __property void set_XmlType(XmlTypeAttribute*);
[JScript]
public function get XmlType() : XmlTypeAttribute;public function set XmlType(XmlTypeAttribute);
プロパティ値
クラス宣言に適用された XmlTypeAttribute をオーバーライドする XmlTypeAttribute 。
解説
XmlTypeAttribute を使用して、型が XmlSerializer によってどのようにシリアル化されるかを制御できます。たとえば、既定では、型がシリアル化されるときは、 XmlSerializer はクラス名を XML 要素名として使用します。 XmlTypeAttribute を作成し、それに XmlType プロパティを設定し、 XmlAttributeOverrides オブジェクトを作成することによって、XML 要素名を変更できます。
使用例
[Visual Basic, C#, C++] XmlTypeAttribute オブジェクトを作成し、そのオブジェクトを XmlAttributes オブジェクトの XmlType プロパティに代入する例を次に示します。
