SoapAttributeOverrides クラス

XmlSerializer を使用してオブジェクトをエンコード済みの SOAP としてシリアル化または逆シリアル化するときに、プロパティ、フィールド、クラスの各属性をオーバーライドできるようにします。

この型のすべてのメンバの一覧については、SoapAttributeOverrides メンバ を参照してください。

解説

SoapAttributeOverrides クラスを使用して、 XmlSerializer が一連のオブジェクトをシリアル化する既定の方法をオーバーライドできます。このようにしてシリアル化をオーバーライドすることには 2 つの利点があります。まず、DLL 内のオブジェクトのシリアル化を、そのソースにアクセスできなくても制御および強化できます。次に、複数のシリアル化可能なクラスをまとめて作成し、それらのオブジェクトを異なる方法でシリアル化できます。たとえば、あるクラス インスタンスのメンバを XML 要素としてシリアル化する代わりに XML 属性としてシリアル化して、トランスポート効率の高いドキュメントにできます。

SoapAttributeOverrides を作成したら、 SoapReflectionImporter クラスの ImportTypeMapping メソッドを使用して、 XmlTypeMapping を作成します。生成されたオブジェクトを引数として XmlSerializer コンストラクタに渡します。このようにして作成された XmlSerializer は、 SoapAttributeOverrides に格納されているデータを使用して、オブジェクトのシリアル化方法を制御する属性をオーバーライドします。このようなオーバーライドを実現するために、 SoapAttributeOverrides には、オーバーライド対象のオブジェクト型のコレクションの他、それらの各オブジェクト型に関連付けられている SoapAttributes が格納されます。各 SoapAttributes には、各フィールド、プロパティ、またはクラスのシリアル化方法を制御する適切な属性オブジェクト セットが格納されています。

SoapAttributeOverrides の作成および使用手順は、次のとおりです。

1. SoapAttributes を作成します。
2. オーバーライドされるオブジェクトに対して適切な属性オブジェクトを作成します。たとえば、フィールドまたはプロパティをオーバーライドするには、新しい派生型を使用して SoapElementAttribute を作成します。オプションとして、新しい ElementName を割り当て、基本クラスの属性名または名前空間をオーバーライドできます。
3. 作成した属性オブジェクトを、 SoapAttributes の適切なプロパティまたはコレクションに追加します。たとえば、 SoapAttributes オブジェクトの SoapElement プロパティに、オーバーライドされるメンバの名前を指定した SoapElementAttribute を設定します。
4. SoapAttributeOverrides を作成します。
5. Add メソッドを使用して、 SoapAttributes を SoapAttributeOverrides に追加します。オーバーライドされるオブジェクトが SoapTypeAttribute の場合は、そのオブジェクトの型を指定するだけで済みます。ただし、フィールドまたはプロパティをオーバーライドする場合は、オーバーライドされるメンバの名前も指定する必要があります。
6. SoapReflectionImporter クラスの ImportTypeMapping メソッドを使用して、 XmlTypeMapping を作成します。
7. XmlSerializer を構築するときに、この XmlTypeMapping を XmlSerializer コンストラクタに渡します。
8. 生成された XmlSerializer を使用して、クラス オブジェクトをシリアル化または逆シリアル化します。

使用例

[Visual Basic, C#, C++] Group 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。 GroupName フィールド、 IgnoreThis フィールド、および GroupType 列挙体のメンバのシリアル化がオーバーライドされます。 CreateOverrideSerializer メソッド内では、 SoapAttributeOverrides が作成され、オーバーライド対象のメンバまたは列挙体ごとに、適切なプロパティが設定された SoapAttributes が作成され、それぞれが SoapAttributeOverrides に追加されています。 XmlTypeMapping が SoapAttributeOverrides を使用して作成され、その XmlTypeMapping を使用して、既定のシリアル化をオーバーライドする XmlSerializer が作成されます。
