android - Android による WCF へのイメージのストリーミング

Question

WCF を実行しているサーバーに画像ファイルを送信するためのこの Android コードがあります。しかし、内部サーバー エラー (コード 500) が返されます。私が持っているコード全体は、構成とその他を含むこれらです...

<bindings>
  <webHttpBinding>
    <binding maxReceivedMessageSize="60000" maxBufferSize="60000" transferMode="Streamed" />
  </webHttpBinding>
</bindings>


      <serviceMetadata httpGetEnabled="true" />
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<services>

  <service name="AndroidWcfService.FileUploaderService">
    <endpoint address="" binding="webHttpBinding" contract="AndroidWcfService.IFileUploaderService" />
  </service>
</services>

そしてこれはインターフェースコードです

 [OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "UploadFile", //"/{pointId}/{ticket}",
      BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat =     WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]       
    int UploadFile(Stream image);

実装

 public int UploadFile(Stream image)
    {
        try
        {
            byte[] f = new byte[10000];

            int bytesRead, totalBytesRead = 0;
            do
            {
                bytesRead = image.Read(f, 0, f.Length);
                totalBytesRead += bytesRead;
            } while (bytesRead > 0);

            byte[] t = new byte[totalBytesRead];
            Array.Copy(f, t, totalBytesRead);

            var fileName = string.Format("{0}.png", DateTime.Now.Ticks);

            fileName = Path.Combine(Environment.CurrentDirectory, fileName);
            var s = File.Create(fileName);
            s.Write(t, 0, totalBytesRead);
            s.Flush();
            s.Close();


            return 1000;
        }
        catch (Exception ex)
        {
            Logger.WriteEntry("UploadFile err:" + ex.Message);
            if (ex.InnerException != null) Logger.WriteEntry("UploadFile err inner exception:" +
                ex.InnerException.Message);
        }
        return -1000;
    }

Androidコードは

 public void uploadFile(File file) {

    HttpClient httpClient = new DefaultHttpClient();

    HttpPost postRequest = new HttpPost("http://test.com:16024/FileUploaderService.svc/UploadFile");
    ResponseHandler<String> responseHandler = new BasicResponseHandler();

    // Indicate that this information comes in parts (text and file)
    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

    try {

        // Create a JSON object to be used in the StringBody
        JSONObject jsonObj = new JSONObject();

        // Add some values
        jsonObj.put("filename", file.getName());

        // Add the JSON "part"
        reqEntity.addPart("entity", new StringBody(jsonObj.toString()));
    } catch (JSONException e) {
        Log.v("App", e.getMessage());
    } catch (UnsupportedEncodingException e) {
        Log.v("App", e.getMessage());
    }

    FileBody fileBody = new FileBody(file);// , "application/octet-stream");
    reqEntity.addPart("image", fileBody);

    try {
        postRequest.setEntity(reqEntity);

        // Execute the request "POST"
        HttpResponse httpResp = httpClient.execute(postRequest);

        // Check the status code, in this case "created"
        if (((HttpResponse) httpResp).getStatusLine().getStatusCode() == HttpStatus.SC_CREATED) {
            Log.v("App", "Uploaded sucessfully!");
        }
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

ここで何が問題なのですか?
