图像未正确上传到 Azure 存储

Question

我正在尝试将图像上传到 Azure 存储。图片确实上传到给定路径，但上传的图片似乎已上传 incompletely/cropped。我在不同的路径上传不同尺寸的图片，但它们都遇到了同样的问题。

我尝试将这些图像保存在本地文件系统上，它们保存得很好。

 public static void saveImage(string fileName, Stream fileContent, string contentType)
        {
            
            fileContent.Seek(0, SeekOrigin.Begin);
            CloudBlockBlob blob = null;

            blob = _blobImageContainer.GetBlockBlobReference(fileName);
            
            byte[] bytes = getByteArray(fileContent);
            bool isCompressableImage = isCompressable(fileName);
            if (isCompressableImage)
            {
                bytes = getCompressedArray(bytes);
            }
            blob.UploadFromByteArrayAsync(bytes, 0, bytes.Length).Wait();
            blob.Properties.ContentType = contentType;
            if (isCompressableImage)
            {
                blob.Properties.ContentEncoding = "gzip";
            }
            blob.SetPropertiesAsync().Wait();
        }

 private static byte[] getByteArray(Stream input)
        {
            byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }

 private static byte[] getCompressedArray(byte[] bytes)
        {
            using (MemoryStream comp = new MemoryStream())
            {
                using (GZipStream gzip = new GZipStream(comp, CompressionLevel.Optimal))
                {
                    gzip.Write(bytes, 0, bytes.Length);
                }
                bytes = comp.ToArray();
            }
            return bytes;
        }

这是正在上传的图片与原始图片的对比示例。

只有部分图片可见，其余部分不可见

正如 Manan Kapoor and Gaurav Mantri 之间讨论的那样，添加要点作为答案以帮助可能面临类似问题的其他社区成员。

The problem was in the way the fileContent stream was being generated.

if (response.StatusCode == HttpStatusCode.OK)
{
Stream receiveStream = response.GetResponseStream();
using (BinaryReader br = new BinaryReader(receiveStream))
{
b = br.ReadBytes(500000);
br.Close();
}
}
