例

次の例では、 という名前 Groupのクラスをシリアル化します。 および フィールドと IgnoreThis 列挙体のGroupNameメンバーのGroupTypeシリアル化がオーバーライドされます。 メソッドでは、 CreateOverrideSerializerSoapAttributeOverrides が作成され、オーバーライドされたメンバーまたは列挙ごとに、 SoapAttributes が適切なプロパティ セットで作成され、 SoapAttributeOverridesに追加されます。 XmlTypeMappingは をSoapAttributeOverrides使用して作成され、XmlTypeMapping既定のシリアル化をオーバーライドする をXmlSerializer作成するために使用されます。

SoapAttributeOverridesクラスを使用すると、 オブジェクトXmlSerializerのセッ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。 この方法でのシリアル化のオーバーライドには、2 つの用途があります。最初に、ソースにアクセスできない場合でも、DLL で見つかったオブジェクトのシリアル化を制御および拡張できます。2 つ目は、シリアル化可能なクラスのセットを 1 つ作成できますが、複数の方法でオブジェクトをシリアル化できます。 たとえば、クラス インスタンスのメンバーを XML 要素としてシリアル化する代わりに、それらを XML 属性としてシリアル化できるため、転送するドキュメントの効率が高くなります。

を作成した後、 SoapAttributeOverridesクラスの メソッドをImportTypeMapping使用して をSoapReflectionImporter作成XmlTypeMappingします。 結果のオブジェクトを引数としてコンストラクターに XmlSerializer 渡します。 結果として得られる XmlSerializer は、 に SoapAttributeOverrides 含まれ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。 これを実現するために、 SoapAttributeOverrides には、オーバーライドされるオブジェクト型のコレクションと、オーバーライドされた各オブジェクト型に SoapAttributes 関連付けられた が含まれます。 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のセットが含まれています。

を作成して使用 SoapAttributeOverrides するプロセスは次のとおりです。

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適した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 SoapElementAttribute使用して を作成します。 必要に応じて、基底クラスの属性名または名前空間をオーバーライドする新しい ElementName を割り当てることができます。

3. 属性オブジェクトを適切な SoapAttributes プロパティまたはコレクションに追加します。 たとえば、 オブジェクトの プロパティを SoapElementSoapAttributes に SoapElementAttribute 設定し、オーバーライドされるメンバー名を指定します。

4. SoapAttributeOverrides を作成します。

5. メソッドを SoapAttributes 使用して、 SoapAttributeOverrides を に Add 追加します。 オーバーライドされるオブジェクトが の SoapTypeAttribute場合は、オーバーライドされたオブジェクトの型のみを指定する必要があります。 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たメンバーの名前も指定する必要があります。

6. クラスの XmlTypeMapping メソッドを ImportTypeMapping 使用して を SoapReflectionImporter 作成します。

7. を構築するときに、 XmlSerializerを XmlTypeMapping コンストラクターに XmlSerializer 渡します。

8. 結果の 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。
