XmlAnyElementAttribute.Namespace プロパティ

[アーティクル]
03/28/2008

XML ドキュメントに生成される XML 名前空間を取得または設定します。

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

プロパティ値

XML 名前空間。

解説

Namespace プロパティを使用すると、XML 属性に一意の名前を設定できます。 Namespace プロパティは、W3C (World Wide Web Consortium) (www.w3.org) のドキュメント『Namespaces in XML』で規定されている、XML 名前空間の作成の規則に準拠しています。

Namespace プロパティにプリフィックス付きの名前を設定するには、XML ドキュメントで使用する名前空間およびプリフィックスを含んだ XmlSerializerNamespaces を作成します。その XmlSerializerNamespaces 内の名前空間のいずれか 1 つを Namespace プロパティに設定します。XML が生成されると、属性名には、指定した名前空間に関連付けられた正しいプリフィックスが付けられます。
