例

次のコード例では、MessageContractAttribute を使用して要求メッセージおよび応答メッセージの両方の SOAP エンベロープ構造を制御し、応答メッセージの SOAP ヘッダーを作成するために MessageHeaderAttribute を使用し、要求メッセージおよび応答メッセージの両方の本文を指定するために MessageBodyMemberAttribute を使用しています。 このコード例には、送信時の各メッセージの例が含まれています。

注釈

MessageBodyMemberAttribute 属性を使用して、データ メンバーが SOAP 本文の中にシリアル化されることを指定し、一部のシリアル化項目を制御します。

Order プロパティを使用して、既定のアルファベット順が適切ではない本体の各部分の順序を指定します。

その他のプロパティは、基本クラスである System.ServiceModel.MessageContractMemberAttribute から継承されます。

既定の SOAP エンベロープ自体を変更せずに SOAP 本文の内容のシリアル化を制御する方法の詳細については、「、サービス コントラクトでのデータ転送の指定」、および「データ コントラクトの使用」を参照してくださいSystem.Runtime.Serialization.DataContractAttribute。

詳細については、「メッセージ コントラクトの使用」を参照してください。
