MTOM を WCF クライアントで動作させようとしています。私が消費しようとしている特定の関数は、MTOM でエンコードされた PDF ドキュメントのバイト配列を送信します。SoapUI を使用して、WSDL を使用して API をテストすると問題なく動作します。ただし、クライアントで同じことをしようとすると、次のエラーが発生します。

今、私はいたるところを検索しましたが、おそらくこれを除いて、このエラーに関連するものを見つけることができません: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/73039d75-e078-436b -a8ab-d8c7197a976b
ただし、そのリンクの推奨事項は私には意味がありません。コードのどこにも、応答メッセージが変更可能なオブジェクトとして存在する場所がありません。だから...ここにいます。私が持っているクライアントは非常に単純です。それは、svcutil によって生成されたプロキシ クラスで構成されています。呼び出しを行うための 10 行のコードと app.config ファイル。構成ファイルに証明書情報を追加し、messageEncoding を Mtom に変更しましたが、それ以上はすべて svcutil によって生成されたままです。
クライアント コードは次のようになります (ご覧のとおり、非常に単純です)。
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.ServiceModel;
using System.Text;
namespace Client
{
class Program
{
static void Main(string[] args)
{
try
{
WsApiServicePortTypeClient client = new WsApiServicePortTypeClient();
byte[] doc = client.getRecordDoc("username0000", "1234567");
File.WriteAllBytes(@"C:\TestRecords\wcf-test.pdf", doc);
Console.WriteLine("Ok, check it now.");
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine("ERROR: " + ex.Message + Environment.NewLine
+ ex.GetBaseException().ToString() + Environment.NewLine

Console.ReadLine();
}
}

プロキシ クラス ファイルの CODEGEN メッセージで示されているように、これはコントラクト ラッパーと関係があると考えています。しかし、そのメッセージについてそれを確認するものは何も見つかりません。
どんな助けでも大歓迎です。
