例

次の例は、HTTP-POST を使用して XML Web サービス ユーティリティを呼び出すための Wsdl.exe ユーティリティによって生成されるプロキシ クラスです。 Wsdl.exe は、プロキシ クラスがHttpPostClientProtocolから継承することを指定すると共に、ReturnFormatterとParameterFormatterの正しい型を自動的に提供します。

注釈

XML Web サービス クライアントが HTTP-GET を使用して XML Web サービス メソッドを呼び出す場合は、ReturnFormatterを XmlReturnReader に設定し、ParameterFormatterUrlParameterWriterに設定する必要があります。 HTTP-POST を使用して XML Web サービスを呼び出す XML Web サービス クライアントは、 ReturnFormatter を XmlReturnReader に設定し、 ParameterFormatter を HtmlFormParameterWriter に設定する必要があります。
