次のスレッドにリストされているのと同じ問題があります。
クライアントがSOAPActionを送信しないWSDLの最初のWCFサーバー
同じスレッドにリストされている手順を実行しました(以下にも表示されています)
1)MicrosoftWCFの例をダウンロードします。WF_WCF_Samples \ WCF \ Extensions \ Interop \ RouteByBody \ CS\serviceからプロジェクトに次のファイルを追加します
DispatchByBodyOperationSelector.cs
DispatchByBodyBehaviorAttribute.cs
2)次の属性をインターフェース(ServiceContractの隣)に追加します
XmlSerializerFormat
DispatchByBodyBehavior
3)サービスインターフェースに以下を追加します
[OperationContract(Action = "")]
public void DoNothing()
{
}
4)私のサービスでは、WrapperNameとWrappernamespaceはすべてのメッセージでnullです。DispatchByBodyBehaviorAttributeに移動し、ApplyDispatchBehavior()を編集して、これを確認するために次の行を追加する必要がありました。
if (qname.IsEmpty) {
qname = new XmlQualifiedName(operationDescription.Messages[0].Body.Parts[0].Name, operationDescription.Messages[0].Body.Parts[0].Namespace);
}
現在、「このメッセージは読み取られたため、操作をサポートできません」というエラーメッセージが表示されます。トレースをオンにして、スタックトレースをキャプチャしました(以下)。これをどのように解決できるかについて誰かが何か考えを持っているなら、コメントを投稿していただければ幸いです。助けてくれてありがとう!
