XmlArrayAttribute.Form プロパティ

定義

XmlSerializer によって生成された XML 要素名が修飾されているかどうかを示す値を取得または設定します。

public:
 property System::Xml::Schema::XmlSchemaForm Form { System::Xml::Schema::XmlSchemaForm get(); void set(System::Xml::Schema::XmlSchemaForm value); };
public System.Xml.Schema.XmlSchemaForm Form { get; set; }
member this.Form : System.Xml.Schema.XmlSchemaForm with get, set
Public Property Form As XmlSchemaForm

プロパティ値

XmlSchemaForm

XmlSchemaForm 値のいずれか 1 つ。 既定値は、XmlSchemaForm.None です。

次の例では、クラスのインスタンスをシリアル化します Enterprises 。 2 つの XML 要素には同じローカル名 (Company) がありますが、プレフィックスは異なります。 この例では、 Form 修飾名が XML インスタンスに確実に存在するようにプロパティを設定 XmlForm.Qualified します。

注釈

このプロパティは Form 、XML 要素名が修飾名か非修飾かを決定します。 このプロパティは Form 、XML の名前空間というタイトルの 1999 World Wide Web Consortium ドキュメント に準拠しています

プロパティが任意の Namespace 値に設定されている場合、例外を Form スローするようにプロパティを XmlSchemaForm.Unqualified 設定しようとしています。

既定の設定では、 XmlSchemaForm.NoneXML ドキュメントの XmlSerializer スキーマをチェックして、名前空間が修飾されているかどうかを判断するように指示します。 スキーマで個々の要素または属性の値が指定されていない場合、XmlSerializer要素または属性が修飾されているかどうかを判断するために、その値とattributeFormDefault値が使用elementFormDefaultされます。 次の XML コードはスキーマを示しています。

<schema elementFormDefault="qualified"   
attributeFormDefault="unqualified"... >  
   <element name="Name"/>  
   <attribute name="Number"/>  
</schema>  

スキーマをXmlSerializer読み取ると、Form要素が修飾されていない間に、Name要素と Number is XmlSchemaForm.Noneの両方NameNumber値が修飾されます。
