我们如何使用librets c#下载房产图片？

我试过这里的代码，但它不工作，显示图片大小为1KB

下面是我试过的代码

 using (librets.GetObjectRequest request = new GetObjectRequest("Property", "Photo"))
                {
                    request.AddAllObjects(CurrentMLS);


                    GetObjectResponse response = session.GetObject(request);

                    foreach (ObjectDescriptor objectDescriptor in response)
                    {
                        string objectKey = objectDescriptor.GetObjectKey();
                        int objectId = objectDescriptor.GetObjectId();
                        string contentType = objectDescriptor.GetContentType();
                        string description = objectDescriptor.GetDescription();

                        Console.Write(objectKey + " object #" + objectId);
                        if (description.Length != 0)
                            Console.Write(", desription: " + description);
                        Console.WriteLine();

                        string outputFileName = photoFilePath+"\\"+objectKey + "-" + objectId + ".jpg";

                        Stream outputStream = File.OpenWrite(outputFileName);
                       
                            const int BUFFER_SIZE = 1024;
                            Stream stream = objectDescriptor.GetDataStream();
                            byte[] buffer = new Byte[BUFFER_SIZE];
                            int bytesRead;
                            while ((bytesRead = stream.Read(buffer, 0, BUFFER_SIZE)) > 0)
                            {
                                outputStream.Write(buffer, 0, bytesRead);
                            }
                       
                        outputStream.Close();
                    }

                }

看起来你不是在按内容类型过滤。如果您信任RETS服务器发送正确格式的内容类型字符串，则可以仅使用以下内容将对象过滤为JPEG：

            string contentType = objectDescriptor.GetContentType();

            // skip objects that don't appear to be JPEGs
            if (contentType != "image/jpeg") { continue; };

关闭原因消息链接令人困惑。我所说的“接近票”的意思是解释发生了什么以及你期望发生什么。在文本编辑器中打开生成的文件
