ファイルを転送するためにWCFを使用しています

クライアント側 [WINFORM]

private void Send(TransferEntry Entry, int bufferSize)
    {
        using (FileStream fs = new FileStream(Entry.SrcPath, FileMode.Open, FileAccess.Read))
        {
            byte[] buffer = new byte[bufferSize];
            long sum = 0;
            int count = 0;
            using (Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
            {
                IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 0);
                listener.Bind(endpoint);
                listener.Listen(1);
                client.Receive(listener.LocalEndPoint, Entry.DestPath, Entry.Size, bufferSize);
                //i get an exception here.
                using (Socket socket = listener.Accept())
                {
                    do
                    {
                        count = fs.Read(buffer, 0, buffer.Length);
                        socket.Send(buffer, 0, count, SocketFlags.None);
                        sum += count;
                        worker.ReportProgress((int)((sum * 100) / Entry.Size));
                    } while (sum < Entry.Size);
                }
            }
        }
    }

WCF [サービス]: IFileManager.cs:

[OperationContract]
    void Receive(System.Net.EndPoint endpoint, string destPath, long size, int bufferSize);

FileManagerService.cs:

public void Receive(EndPoint endpoint, string destPath, long size, int bufferSize)
    {
        using (Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
        {
            client.Connect(endpoint);
            using (FileStream fs = new FileStream(destPath, FileMode.Create, FileAccess.Write))
            {
                byte[] buffer = new byte[bufferSize];
                long sum = 0;
                int count = 0;
                do
                {
                    count = client.Receive(buffer, 0, buffer.Length, SocketFlags.None);
                    fs.Write(buffer, 0, count);
                } while (sum < size);
                fs.Flush();
            }
        }
    }

次に、クライアント側でこの例外が発生しました[Winform]：

System.ServiceModel.CommunicationException was unhandled by user code Message=There was an error while trying to serialize parameter http://tempuri.org/:endpoint. The InnerException message was 'Type 'System.Net.IPEndPoint' with data contract name 'IPEndPoint:http://schemas.datacontract.org/2004/07/System.Net' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details.

EndPointパラメータを渡したときにのみこれが発生するのはなぜですか! どうすればそれを機能させることができますか？

サーバーは を予期してEndPointいますが、送信していますIPEndPoint.

ServiceKnownTypeAttributeIPEndPointの使用を期待するようにサービスに指示することで、これを修正できます。
