SoapEnumAttribute コンストラクタ ()

SoapEnumAttribute クラスの新しいインスタンスを初期化します。

名前空間: System.Xml.Serialization
アセンブリ: System.Xml (system.xml.dll 内)

構文

'宣言
Public Sub New
'使用
Dim instance As New SoapEnumAttribute

public SoapEnumAttribute ()

public:
SoapEnumAttribute ()

public SoapEnumAttribute ()

public function SoapEnumAttribute ()

解説

既存の列挙体をオーバーライドするには、SoapEnumAttribute を使用します。新しい SoapEnumAttribute を作成し、プロパティを設定し、このオブジェクトを SoapAttributes の SoapEnum プロパティに代入します。列挙体のメンバごとに、新しい SoapAttributes を作成し、それを SoapAttributeOverrides に追加する必要があります。詳細については、SoapAttributeOverrides クラスの概要を参照してください。

注意

コードでは、SoapEnumAttribute の代わりに SoapEnum という短い語を使用できます。

使用例

XmlSerializer を使用して、FoodType という名前の列挙体を含んでいる Food という名前のクラスをシリアル化する例を次に示します。各列挙体の SoapEnumAttribute を作成し、該当する SoapEnumAttribute を SoapAttributes の SoapEnum プロパティに設定することにより、FoodType 列挙体をオーバーライドしています。この SoapAttributes が、XmlSerializer を作成するために使用される SoapAttributeOverrides に追加されます。
