从库中选择图像,我可以上传流,但得到错误"参数无效".在尝试转换为WCF中的图像时.

Android代码创建与REST服务的连接,并将图像上传为Byte []:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);

  if (resultCode == RESULT_OK){
    Uri targetUri = data.getData();

    Bitmap bitmap;
    try {
      bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri));
      ByteArrayOutputStream out = new ByteArrayOutputStream();

      bitmap.compress(Bitmap.CompressFormat.JPEG, 6, out);

      DefaultHttpClient httpClient = new DefaultHttpClient();

      byte[] sendData = out.toByteArray();

      HttpPost postRequest = new HttpPost("http://www.thehost.dk/MobileService/Service.svc/uploadpicture/");
      ByteArrayBody bab = new ByteArrayBody(sendData, "picture.jpg");
      MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
      reqEntity.addPart("image", bab);
      postRequest.setEntity(reqEntity);
      httpClient.execute(postRequest);

WCF C#代码接收流并尝试转换为图像,但收到错误:

    public void UploadPicture(Stream imageData)
    {
        try
        {
            byte[] image = StreamToBytes(imageData); …
