私はしばらくこれに苦労していて、本当にいくつかの助けを使うことができました。

サーバーへの画像のストリーミングを可能にし、imageURL（つまり、「http://images.site.com/someimage.jpg」）を返すWCFエンドポイントを設計しようとしています。

現在、私のWCFメソッドの呼び出しは次のようになっています。

for (var i = 0; i <= (Request.Files.Count - 1); i++)
{
client = new SOAPFileTransferServiceClient();
fileinfo = new FileTransferInfo();
m_objFile = Request.Files[i];

if (!(m_objFile == null | string.IsNullOrEmpty(m_objFile.FileName) |  _objFile.ContentLength < 1))
   {

   fileinfo.FileSize = m_objFile.ContentLength;
   fileinfo.FileName = Path.GetFileName(m_objFile.FileName);
   fileinfo.UserID = Context.Request["sid"].ToString();

   client.UploadFile(fileinfo, m_objFile.InputStream);

   if (retParam.param2 == 0)
   imgurl.Add(retParam.param1);

  }

}

私が苦労しているエラーはこれです：

転送モードStreamedは、ReliableSessionBindingElementではサポートされていません。

これまで、メッセージエンコーディング要素の前に追加されたカスタムnetTcpバインディングを作成してみました。また、transerMode属性をstreamedRequestに変更し（marc_sによる提案のおかげで）、要求はストリーミングされますが、応答は許可されません。これでうまくいくようですが、それでも同じエラーが発生します（今回は「転送モードStreamedRequestは...ではありません...」）。

私は考えが足りません。

以下はファイル転送サービス契約です。SOAPエンドポイントに加えてJSONとPOXがあります。また、2つのMEXエンドポイントがあります（1つはmexHttp用、もう1つはnetTcp用）。最後に、http（jsonとpoxの場合）とnetTcp（soapの場合）の両方のベースアドレスがあります。

何か問題がありますか？

<service behaviorConfiguration="transferServiceBehavior" name="MyProject.API.FileTransfer.FileTransferService">
            <endpoint address="json" behaviorConfiguration="WebHttpEPBehavior"
              binding="webHttpBinding" bindingConfiguration="jsonWeb" name="MyJSONFileTransferEP"
              contract="MyProject.API.FileTransfer.IJSONFileTransferService" />
            <endpoint address="pox" behaviorConfiguration="WebHttpEPBehavior"
              binding="webHttpBinding" bindingConfiguration="poxWeb" name="MyPOXFileTransferEP"
              contract="MyProject.API.FileTransfer.IPOXFileTransferService" />
            <endpoint address="httpMex" binding="mexHttpBinding" bindingConfiguration=""
              contract="IMetadataExchange" />
            <endpoint address="soap" behaviorConfiguration="NetTcpEPBehavior"
              binding="customBinding" bindingConfiguration="netTcpCustom"
              name="MySOAPFileTransferEP" contract="MyProject.API.FileTransfer.ISOAPFileTransferService" />
            <endpoint address="nettcpMex" binding="netTcpBinding" bindingConfiguration=""
              contract="IMetadataExchange" />
            <host>
              <baseAddresses>
                <add baseAddress="http://localhost:2544/filetransfer/" />
                <add baseAddress="net.tcp://localhost:2544/filetransfer/" />
              </baseAddresses>
            </host>
          </service>

そして、これがサービス契約で使用される私のカスタムバインディングです：

<customBinding>
    <binding name="netTcpCustom"
             closeTimeout="00:01:00"
             openTimeout="00:01:00"
             receiveTimeout="00:10:00"
             sendTimeout="00:01:00">

      <oneWay />
      <windowsStreamSecurity protectionLevel="None" />
      <mtomMessageEncoding  />
      <tcpTransport maxBufferPoolSize="524288"
                    maxReceivedMessageSize="2147483647"
                    connectionBufferSize="8192"
                    hostNameComparisonMode="StrongWildcard"
                    channelInitializationTimeout="00:01:00"
                    maxBufferSize="2147483647"
                    maxPendingConnections="20"
                    maxOutputDelay="00:00:00.2000000"
                    maxPendingAccepts="5"
                    transferMode="StreamedRequest"
                    listenBacklog="20"
                    portSharingEnabled="false"
                    teredoEnabled="false">
        <connectionPoolSettings groupName="default" leaseTimeout="00:05:00"
            idleTimeout="00:02:00" maxOutboundConnectionsPerEndpoint="20" />
      </tcpTransport>
    </binding>
  </customBinding>

信頼できるセッション要素を削除した場合、StreamedRequestメソッドは機能しますか？あなたはそれと一緒に暮らすことができますか？netTcpを使用している場合は、おそらく企業ファイアウォールの背後にいますよね？したがって、信頼できるセッションオーバーヘッドなしで逃げることができるかもしれません。

また、-WCFには非常に多くのオプションと機能の可能な組み合わせがあります-すべてが理にかなっているわけではなく、すべてが連携して機能するわけではありません-おそらくこれはWCFの制限であり、構成上の問題ではありません。

構成の唯一の奇妙な点は、netTcpカスタムバインディングのmtomMessageEncodingです-はるかに効率的なバイナリエンコーディングを使用してみませんか？
