という名前Vehicleのフィールドを含む、というTransportation名前のクラスのインスタンスをシリアル化する例を次に示します。The following example serializes an instance of a class named Transportation that contains a field named Vehicle. フィールドSoapElementAttributeにが適用されます。A SoapElementAttribute is applied to the field. フィールドをシリアル化すると、XML 要素名は "車両" ではなく "車輪" になります。When the field is serialized, the XML element name is "Wheels" instead of "Vehicle". メソッドSerializeOverrideは、をSoapElementAttribute作成し、 SoapElementのプロパティをSoapAttributesSoapElementAttribute設定します。The SerializeOverride method creates a SoapElementAttribute and sets the SoapElement property of a SoapAttributes to the SoapElementAttribute. は、の作成SoapAttributeOverrides XmlTypeMappingに使用されるに追加されます。 SoapAttributesThe SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlTypeMapping. はをTransportation使用して構築され、クラスのインスタンスは再びシリアル化されます。 XmlSerializer XmlTypeMappingAn XmlSerializer is constructed with the XmlTypeMapping, and an instance of the Transportation class is again serialized. は、 SoapElementAttributeシリアル化をオーバーライドするために使用されるため、生成される XML 要素名は "車輪" ではなく "トラック" になります。Because the SoapElementAttribute is used to override the serialization, the generated XML element name is now "Truck" instead of "Wheels".

注釈

クラスSoapElementAttributeは、がオブジェクトをエンコード済みのXmlSerializer SOAP XML としてシリアル化または逆シリアル化する方法を制御する属性のファミリに属しています。The SoapElementAttribute class belongs to a family of attributes that controls how the XmlSerializer serializes or deserializes an object as encoded SOAP XML. 生成される XML は、World Wide Web コンソーシアムドキュメント「 Simple Object Access Protocol (SOAP) 1.1」のセクション5に準拠しています。The resulting XML conforms to section 5 of the World Wide Web Consortium document, Simple Object Access Protocol (SOAP) 1.1. 類似する属性の完全な一覧については、「エンコード済み SOAP シリアル化を制御する属性」を参照してください。For a complete list of similar attributes, see Attributes That Control Encoded SOAP Serialization.

オブジェクトをエンコードXmlTypeMapping済みの SOAP メッセージとしてシリアル化するにXmlSerializerは、 SoapReflectionImporterクラスのImportTypeMappingメソッドを使用して作成されたを使用してを構築する必要があります。To serialize an object as an encoded SOAP message, you must construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

をパブリックフィールドXmlSerializer に適用して、フィールドをエンコード済みのSOAPXML要素としてシリアル化するようににSoapElementAttribute指示します。Apply the SoapElementAttribute to a public field to direct the XmlSerializer to serialize the field as an encoded SOAP XML element.
